Description

Technical Field

[0001] The present disclosure relates to a management device, a management method, a management program, and a management system for managing facilities.

Background Art

[0002] In the transaction of a power transmission line, which is one of the facilities, generally, a manufacturing company creates an estimate in response to a request from a company that wishes to make a purchase (hereinafter referred to as a customer company). The power transmission line is a concept that includes an uncoated wire such as a bare wire or an insulated wire, a CV (cross-linked polyethylene insulated vinyl sheath cable), and an OF cable. The customer company examines the contents of the estimate and places an order. The manufacturing company places an order for each part required for the production of the ordered product, the quantity, the time required from the order to the delivery of each part (hereinafter referred to as the delivery lead time), the time required for manufacturing, and the schedule on which the construction contractor can perform the wire laying work, etc., and places an order for each part so as to meet the delivery date (designated delivery date) of the ordered product.

[0003] Here, when there is no stock of the parts required for the production of the ordered product, the production will be carried out according to the part or material with the longest delivery lead time, and there is a possibility that the request for a short delivery period cannot be met.

[0004] Therefore, a technique has been proposed in which a safety stock is set for parts or materials with a long delivery lead time to secure stock, and if the quantity is within the range of the safety stock, production can be carried out without being affected by the delivery lead time of the parts (see, for example, Patent Document 1).

Summary of the Invention

Problems to be Solved by the Invention

[0006] However, when the inventory level is set low, since there is no surplus inventory, it is possible to reduce the costs for the manufacturer to manufacture and store the inventory. However, when there is an order exceeding the inventory level, it becomes difficult to respond within the delivery lead time, and it is impossible to meet the request for a short delivery time, which will affect the operation of the customer company. On the other hand, when the inventory quantity is set high, it is possible to provide equipment in response to an order from the customer company without affecting the operation of the customer company. However, when the order situation continues to be below the inventory quantity, the inventory will be held for a long time, making it difficult to reduce the costs for the manufacturer to manufacture and store the inventory. As a result, it may not be possible to maintain the social infrastructure, or the maintenance cost of the social infrastructure may increase.

[0007] An object of the present invention is to provide a management device, a management method, a management program, and a management system that can maintain the social infrastructure by suppressing the influence on the operation of the customer company and suppressing the costs for the manufacturer to manufacture and store the equipment, and can suppress the maintenance costs.

MODE FOR CARRYING OUT THE INVENTION

[0029] Hereinafter, the configurations and operations of a management device, a management method, a management program, and a management system for managing facilities according to the present embodiment will be described in detail with reference to the drawings. Note that the present invention is not limited by the contents described in the following embodiments. In addition, the constituent elements described below include those that can be easily assumed by those skilled in the art and those that are substantially the same. Furthermore, the constituent elements described below can be combined as appropriate.

[0030] (Regarding the Configuration of the Management System) FIG. 1 is a diagram showing the configuration of a management system 100 including a server 2 and a management device 1 for managing the inventory of the facilities according to this embodiment. In the management system 100, the customer terminal device 3 and the management device 1 are interconnected via a network NW1. In this embodiment, when referring to the "customer terminal device 3", it may refer to a plurality of customer terminal devices 3a, 3b, ···, 3n individually or a plurality of customer terminal devices 3a, 3b, ···, 3n as a whole. Note that, although it is better to have more customers, the effects of this embodiment can also be achieved by one company.

[0031] Further, the management device 1 is an apparatus operated by a company (hereinafter referred to as the equipment manufacturing and management company) or an organization that manufactures the equipment and manages the inventory of the equipment. The equipment is a member laid on a building, a road, etc., regardless of indoors or outdoors, and examples thereof include electric wires (including communication wires and power lines), utility poles, power-related equipment (insulators, transformers, connection parts, etc.), optical fibers, and optical fiber-related equipment (closures). In this embodiment, an electric wire will be described as a representative example of the equipment. The customer terminal device 3 is an apparatus operated by a company or an organization that receives the equipment manufactured by the equipment manufacturing and management company.

[0032] In the management system 100, the construction contractor terminal device 4 and the management device 1 are interconnected via a network NW2. In this embodiment, when referring to the "construction contractor terminal device 4", it may refer to a plurality of construction contractor terminal devices 4a, 4b, ···, 4n individually or a plurality of construction contractor terminal devices 4a, 4b, ···, 4n as a whole. The construction contractor terminal device 4 is an apparatus operated by a company or an organization that lays the equipment manufactured by the equipment manufacturing and management company.

[0033] In the management system 100, a management device 1 and a server 2 are connected. In the present embodiment, when referring to the "server 2", it may individually indicate a plurality of servers 2a, 2b, 2c or may indicate the plurality of servers 2a, 2b, 2c as a whole. Note that the plurality of servers 2a, 2b, 2c may be configured by one server. Also, the server 2 may be configured to be interconnected with the management device 1 via the network NW1 or the network NW2.

[0034] Also, in the configuration example shown in FIG. 1, the network NW1 and the network NW2 are shown as separate networks, but the present invention is not limited to this configuration, and they may be the same network.

[0035] (Configuration of the management device) As shown in FIG. 1, the management device 1 includes a first registration unit 11, a first calculation unit 13, a determination unit 14, a first ordering unit 15, a calculation unit 16, and a presentation unit 17.

[0036] The first registration unit 11 registers customer information including at least information about the facilities used by the customer. Here, the customer information will be described. The customer uses the customer terminal device 3 to fill in the necessary items in a predetermined registration form provided by the management device 1. Also, the customer transmits the registration form with the necessary items filled in to the management device 1. The first registration unit 11 generates customer information based on the content of the registration form received from the customer terminal device 3.

[0037] FIG. 2 is a diagram schematically showing customer information I1. The customer information I1 is generated for each customer ID that uniquely identifies the customer, and includes information such as a facility ID which is an ID (identification) for uniquely identifying the facility, the laying date of this facility, the service life of the facility, and the manufacturing date of the facility. The first registration unit 11 stores the generated customer information I1 in the server 2a.

[0038] Based on the information about the facilities included in the customer information I1, the first calculation unit 13 obtains the total number for each type of facility, and calculates the first inventory quantity for each type of facility based on the total number.

[0039] Here, the operation of the first calculation unit 13 will be described. The first calculation unit 13 accesses the server 2a, reads out the customer information I1, and generates facility information based on the read customer information I1. FIG. 3 is a diagram schematically showing the facility information I2 for each facility (inventory) that needs to be replaced. The facility information I2 is generated for each type of facility. In the example shown in FIG. 3, the facility information I2_1 for electric wires (for power), the facility information I2_2 for electric wires (for communication), and the facility information I2_n for optical fibers are shown as facilities, but it is not limited thereto. Also, the facility information I2 shows the number of units that need to be replaced for each customer ID. The total number (total number of units) of facilities that need to be replaced is the value obtained by summing up the number of units for each facility. The facility information I2 is stored in the server 2a, for example.

[0040] The first inventory quantity is a number less than the total number of facilities that need to be replaced. Specifically, the first calculation unit 13 may be configured to calculate the first inventory quantity by using a table or a function that calculates the first inventory quantity based on the total number N of electric wires that need to be replaced.

[0041] Also, the rule for calculating the first inventory quantity may be changed according to the type of facility. For example, when the total number (number of units) of electric wires (used for signal transmission) is 600, the first calculation unit 13 may reduce it by 50% (the first inventory quantity is 300), or reduce it by 90% (the first inventory quantity is 60), etc. Also, when the total number (number of units) of electric wires (used for power transmission) is 600, the first calculation unit 13 may reduce it by 40% (the first inventory quantity is 360), or reduce it by 80% (the first inventory quantity is 120), etc. There is a social demand to shorten the delivery lead time after disconnection for both electric wires (used for signal transmission) and electric wires (used for power transmission). Here, for example, electric wires (used for signal transmission) can sometimes be temporarily restored using a mobile wireless vehicle, etc. Therefore, the inventory quantity may be determined while considering those situations.

[0042] The determination unit 14 compares the first inventory quantity calculated by the first calculation unit 13 with the actual inventory quantity of the equipment, and determines whether the actual inventory quantity of the equipment is insufficient. As described above, the first inventory quantity is calculated based on the total number N of electric wires that will need to be replaced in the future. Therefore, generally, as the total number N increases, the first inventory quantity also increases, and as the total number N decreases, the first inventory quantity also decreases. However, the increase rate or decrease rate of the total number N and the increase rate and decrease rate of the first inventory quantity are not the same. For example, even when the total number N increases from 600 to 900 (the increase rate is +150%), the first inventory quantity does not increase by 150%. That is, it is possible to reduce the resources that should be secured to maintain the infrastructure.

[0043] FIG. 4 is a diagram schematically showing a table T1 indicating the inventory quantity for each piece of equipment. The table T1 indicating the actual inventory quantity of the equipment is stored in the server 2b and is updated so as to always show the latest inventory quantity. In the example shown in FIG. 4, a table T1_1 indicating the inventory quantity of electric wires (power), a table T1_2 indicating the inventory quantity of electric wires (communication), and a table T1_n indicating the inventory quantity of optical fibers are shown, but it is not limited thereto.

[0044] When the determination unit 14 determines that the actual inventory quantity of the equipment is insufficient, the first ordering unit 15 places an order for the manufacture of the insufficient equipment. In response to the order from the first ordering unit 15, the company that manages the management device 1 starts manufacturing the equipment.

[0045] The calculation unit 16 calculates the payment amount for each customer registered by the first registration unit 11 based on the cost related to the replacement of the equipment. Specifically, the calculation unit 16 calculates the payment amount for each customer registered by the first registration unit 11 based on the information indicating the service life for each type of equipment calculated by the second calculation unit 12, which will be described in detail later, based on the cost related to the replacement of the equipment. The cost related to the replacement of the equipment includes costs such as the cost of manufacturing the replacement, the cost of storing the substitute, the cost of transporting the replacement to the site, and the cost of installing the replacement. In addition, the cost related to the replacement of the equipment may also include the cost related to the pre - handling before the replacement of the equipment. Also, the payment amount may be paid in a lump sum or in installments. Hereinafter, the money paid in installments is referred to as the accumulated amount.

[0046] For example, if the service life of a certain piece of equipment is 20 years and the cost related to the replacement of the equipment is set at 120 million yen, the monthly accumulated amount will be 500,000 yen. Also, if the service life of a certain piece of equipment is 20 years and the cost related to the replacement of the equipment is set at 12 million yen, the monthly accumulated amount will be 50,000 yen.

[0047] The presentation unit 17 presents the payment amount calculated by the calculation unit 16 to the customer. Specifically, the presentation unit 17 notifies the corresponding customer terminal device 3 via the network NW1 of the information related to the payment amount. For example, in the case of the accumulated amount for which the payment amount is paid in installments, the customer deposits the accumulated amount into the designated bank account by the designated due date every month.

[0048] In this way, the management device 1 can receive the payment related to the equipment from the customer in advance, and use this payment amount as the original capital to manufacture the equipment, so that the manufacturing and storage costs of the equipment by the manufacturing company can be suppressed.

[0049] Also, when the determination unit 14 determines that the actual inventory of the equipment is insufficient, the management device 1 orders the manufacturing of the equipment by the first ordering unit 15, so that a certain inventory can be secured and the impact on the operation of the customer company due to the inventory shortage can be suppressed.

[0050] As described above, the management device 1 can suppress the impact on the operation of the customer company and can also suppress the costs for the manufacturing and storage of the equipment by the manufacturing company. As a result, it is possible to maintain the social infrastructure and suppress the maintenance costs thereof.

[0051] (Regarding the operation of the second calculation unit) The management device 1 includes a second calculation unit 12. The second calculation unit 12 accesses the server 2a, reads out the customer information I1, and calculates information indicating the service life for each type of equipment based on the information regarding the equipment included in the read customer information I1 (for example, the service life of the equipment, the manufacturing date of the equipment, etc.).

[0052] The information indicating the service life for each type of equipment is information indicating the service life of the equipment, or information indicating an extension or shortening of the service life of the equipment. The service life of the equipment may be indicated, for example, as "20 years later" or "30 years later", or may be indicated as "20 to 30 years later" or "30 to 35 years later". The details of the calculation procedure for the service life of the equipment will be described later.

[0053] The information indicating an extension or shortening of the service life of the equipment may be indicated, for example, as "service life + service life × 20%", "service life - service life × 20%", or "service life ± service life × 20%". For example, if the service life of the equipment was 20 years, but the actual replacement period was 15 years, it is assumed that the service life was shortened (shortened by 25%) due to the environmental conditions at the location where the equipment was installed. In this case, the second calculation unit 12 calculates "20 years - 5 years (20 years × 25%)" as the information indicating an extension or shortening of the service life of the equipment.

[0054] The first calculation unit 13 obtains the total number for each type of equipment based on the information regarding the equipment included in the customer information I1. The first calculation unit 13 calculates the first inventory number for each type of equipment based on the total number and the information indicating the service life for each equipment calculated by the second calculation unit 12.

[0055] The first calculation unit 13 calculates the first inventory quantity by M / N based on the total number N of wires that need to be replaced and the service life (average value of the service life) M of the wires calculated by the second calculation unit 12. For example, when the total number of wires that need to be replaced is 600 and the service life (average value of the service life) of the wires calculated by the first calculation unit 13 is 20 years, the second calculation unit 12 sets 30 (=600 / 20) as the first inventory quantity in the first year.

[0056] Also, the first calculation unit 13 may calculate the first inventory quantity based on dividing the service life and based on the total number of wires belonging to those service lives. For example, the i-th group is set every 10 years. Let it be the first group (0 to 10 years), the second group (11 to 20 years), and the third group (21 to 30 years). Also, regarding the number of wires Ni belonging to each group, assume that it is 100 as N1 in the first group, 300 as N2 in the second group, and 200 as N3 in the third group. Assuming that each group holds a ratio R of 1 / 10 as inventory, it may be 10 (N1×R) in the first group, 30 (N2×R) in the second group, and 20 (N3×R) in the third group, respectively.

[0057] Also, the first calculation unit 13 may calculate the first inventory quantity by using a table for calculating a predetermined first inventory quantity based on the total number N of wires that need to be replaced and the service life (average value of the service life) M of the wires calculated by the second calculation unit 12. For example, when the total number of wires that need to be replaced is 600 and the service life (average value of the service life) of the wires calculated by the first calculation unit 13 is 20 years, it may be a 50% reduction (the first inventory quantity is 300), and when the total number of wires that need to be replaced is 600 and the service life (average value of the service life) of the wires calculated by the first calculation unit 13 is 40 years, it may be a 90% reduction (the first inventory quantity is 60), etc.

[0058] (Procedure for calculating service life_1) The second calculation unit 12 calculates the service life based on, for example, the "service life" and "manufacture date" included in the customer information I1 shown in FIG. 2. Here, the service life will be described. For facilities laid in these buildings including structures, generally, a design service life (such as 10 to 20 years) is defined. Also, the service life may be indicated by the number of years such as "20 years" or "30 years", or may be indicated by a period such as "20 years to 30 years" or "30 years to 40 years".

[0059] The second calculation unit 12 obtains the replacement time from the service life and the manufacture date, and calculates the service life from the replacement time and the calculation date. For example, when the service life is "30 years", the manufacture date of the facility is "October 9, 1998", and the calculation date is "October 10, 2020", the second calculation unit 12 obtains the replacement time as "October 2028" and calculates the service life as "(remaining) 8 years".

[0060] (Procedure for calculating service life_2) As described above, for facilities laid in these buildings including structures, generally, a design service life (such as 10 to 20 years) is defined. However, due to the laying environment and usage conditions of the facilities, etc., the facilities deteriorate more than expected and this service life changes. For example, as deterioration factors of electric wires which are an example of facilities, electrical factors such as overvoltage and overcurrent, water ingress into the electric wire, mechanical factors (vibration, impact, compression, bending, etc.), thermal factors (decrease in physical properties due to high or low temperature), ultraviolet rays and salt adhesion (decrease in physical properties), deterioration by microorganisms, poor construction, etc. can be considered. Also, when a plurality of these deterioration factors are combined, the deterioration of the facilities is further promoted, and replacement may be required before the service life. Also, even for the same facility, if the laying environment and usage conditions, etc. are different, the deterioration states are individually different and the service lives are different.

[0061] In particular, in the case of long structures such as electric wires and optical fibers (for example, 10 m or more, more preferably 100 m or more), even if they are integral objects, the structure, laying environment, or usage conditions may vary depending on the part, resulting in different degradation states. For example, in a power transmission line, the structure of the terminal part and the wire part is different. Also, when the wire part is laid over a long distance (for example, several km), even in the same wire part, parts with different laying environments or usage conditions may occur. As a result, the service life and degradation state will vary depending on the part.

[0062] Therefore, the second calculation unit 12 is configured to calculate the service life of the facility based on the laying environment or usage conditions. Specifically, the second calculation unit 12 uses a prediction model generated based on information on the facility provided from an external device, and calculates (actually, predicts) the service life of the facility based on the information on the facility included in the customer information I1. The information on the facility provided from the external device is, for example, information on the facility (delivery time, product name, lot, laying year, used material, etc.), environmental information around the facility (water, humidity, temperature, etc.), information on the reference facility (fact that it broke in 20 years, product name, lot, laying year, used material, etc.), and environmental information around the reference facility (water, humidity, temperature, etc.).

[0063] FIG. 5 is a diagram showing the configuration of the second calculation unit 12. The second calculation unit 12 includes a learning unit 51, a data processing unit 52, and an analysis and prediction unit 53.

[0064] The learning unit 51 performs learning based on a plurality of data stored in the server 2, and generates a plurality of prediction models from the results of the learning. In this embodiment, the case where the prediction model is generated using machine learning, deep learning, etc. will be described, but it is not limited to this, and it may be generated using regression calculation.

[0065] Here, the operation of the learning unit 51 will be described. The learning unit 51 performs learning based on a plurality of data stored in the server 2, and generates a prediction model regarding the deterioration factors and service life of the equipment from the learning results. In the server 2, the first information I3, the second information I4, and the third information I5 are associated with each equipment ID. The first information I3, the second information I4, and the third information I5 are information provided by those who operate and manage the equipment (for example, the administrator of the customer terminal device 3).

[0066] FIG. 6 is a diagram schematically showing an example of the first information I3. FIG. 7 is a diagram schematically showing an example of the second information I4. FIG. 8 is a diagram schematically showing an example of the third information I5.

[0067] As shown in FIG. 6, the first information I3 includes information such as the equipment ID, the manufacturing date indicating the year, month, and day when the equipment was manufactured, the manufacturing company name indicating the company that manufactured the equipment, the specification information indicating the rated voltage, rated temperature, etc. of the equipment, the laying date indicating the year, month, and day when the equipment was laid, the laying contractor name indicating the contractor that laid the equipment, the worker name indicating the name of the worker who actually laid the equipment, and the environmental information (information such as temperature, humidity, and weather) indicating the environment when the equipment was laid. Note that the items included in the first information I3 are not limited to the items shown in FIG. 6.

[0068] The equipment ID is given the same ID for the same equipment based on the shape (flat type, round type, etc.), use (for communication, for power, etc.), material name (vinyl, polyethylene, etc.), size, etc. of the equipment.

[0069] Also, the equipment ID may be given a unique ID for each manufacturing company. In this case, the management device 1 edits the equipment ID so that the same ID is given to equivalent products based on a predetermined conversion table or the like.

[0070] As shown in FIG. 7, the second information I4 is information in which information on changes in the environment around the facility and information on changes in the environment inside the facility (hereinafter sometimes referred to as sensing information) obtained by various sensors for each facility ID are configured in time series. The sensing information includes the temperature, humidity, internal pressure, water immersion amount, temperature of the cable main body, bending condition, tension condition, and stress of the cable inside the facility housing. Note that FIG. 7 schematically shows the second information I4 of "facility ID: 0000000a" as a representative.

[0071] The sensing information is information such as the temperature, humidity, vibration frequency, bending condition, tension condition, and stress of the cable around the facility. Note that the sensing information is not limited to the temperature, humidity, vibration frequency, bending condition, tension condition, and stress of the cable around the facility, and may include the solar radiation amount, ultraviolet ray amount, acidity of precipitation, etc. around the facility.

[0072] Various sensors for detecting temperature, humidity, vibration, water immersion, etc. are arranged around the facility. The various sensors sense temperature, etc. at predetermined timings. The predetermined timings are, for example, every 10 minutes, every 30 minutes, every hour, etc. The timing of data sensing and the timing of data transmission do not have to be the same. Also, it is desirable to obtain the data online using wired or wireless means, but the data may also be obtained offline using a robot or by hand. Furthermore, an environmental evaluation test piece that does not use an electronic circuit may be used. That is, for example, a sensor that changes color when it touches water may be arranged and the change in its color may be analyzed offline.

[0073] Also, the second information I4 may be composed of data obtained by averaging the data sensed by various sensors for each predetermined period. For example, in the case of air temperature, it may be shown by the average value in the morning and the average value in the afternoon every day, or it may be shown by the minimum air temperature and the maximum air temperature.

[0074] Further, the second information I4 may be composed of all data sensed by various sensors. In this case, the management device 1 may perform processing such as averaging each data included in the second information I4 at predetermined intervals.

[0075] As shown in FIG. 8, the third information I5 is information including an equipment ID, date and time information indicating the date and time when the deterioration state of the equipment was confirmed, information such as the deterioration state of the equipment, etc. Note that the items included in the third information I5 are not limited to the items shown in FIG. 8.

[0076] The deterioration state of the equipment is information that serves as a guide for equipment repair and replacement. The deterioration state in the case of an electric wire covered by the equipment will be described. For example, when the electric wire is disconnected and replaced, it is set as the "A" state, when there is a change (such as discoloration, deterioration, corrosion, dust adhesion, etc.) in the appearance of the electric wire (sheath (outer skin)), it is the "B" state, and when there is no change in the appearance of the electric wire, it is the "C" state, etc.

[0077] Note that the data related to the equipment may include information other than the first information I3, the second information I4, and the third information I5. For example, it may also include information related to maintenance records (equipment inspection records, failure repair records), etc. Means for inputting data related to the equipment include a keyboard, a camera, a video, various sensors, etc. Further, the data input from a keyboard or the like may be secondary data obtained by calculation and processing and used as data related to the equipment.

[0078] For example, the learning unit 51 extracts the equipment ID for which the deterioration state of the equipment is in the "A" state based on the third information I5.

[0079] The learning unit 51 extracts information that can be a degradation factor from the information associated with the extracted equipment ID. The information that can be a degradation factor means data related to high-quality equipment. For example, the laying contractor name, the operator name, the information on the environment when the equipment was laid, which is included in the first information I3, the sensing information, the period until the degradation state of the equipment reaches the "A" state, etc., which are included in the second information I4. The period until the degradation state of the equipment reaches the "A" state can be calculated, for example, from the laying date included in the first information I3 and the date and time information included in the third information I5.

[0080] The laying contractor name, the operator name, and the information on the environment when the equipment was laid are information that can be the cause of construction defects. For example, the equipment laid by operator A may have a shorter service life than the equipment laid by other operators in some cases. In such a case, the name of this operator A corresponds to the information that is the characteristic of the degradation factor.

[0081] The sensing information can be information such as water ingress into the wire, the presence of water around the wire, mechanical factors (vibration, impact, compression, bending, etc.), thermal factors (decrease in physical properties due to high temperature or low temperature), and other environmental factors (humidity, solar radiation). In particular, it is desirable to measure the influence of water.

[0082] Based on the extracted information that can be a degradation factor, the learning unit 51 learns the characteristics of each degradation factor, and from the learned results, generates a prediction model regarding the degradation factor and the service life for each piece of equipment.

[0083] In addition, the learning unit 51 may be configured to automatically evaluate a prediction model generated once at a predetermined timing and perform a process of updating based on this evaluation. Specifically, when the learning unit 51 detects a decrease in accuracy for a certain prediction model, it automatically updates this prediction model. For example, the learning unit 51 may detect a decrease in accuracy triggered by a decrease in the number of times the prediction model is used. By being configured in this way, the learning unit 51 can maintain the prediction accuracy (the quality of the prediction model). Further, information regarding the decrease in this prediction accuracy may be notified to the administrator of the management device 1 and the person who provided the information of the first information I3, the second information I4, and the third information I5 (for example, the administrator of the customer terminal device 3).

[0084] The data processing unit 52 processes the customer information I1 registered by the first registration unit 11. For example, the data processing unit 52 processes the customer information I1 to identify the facility ID, the environmental information where the facility is laid, and the like.

[0085] The analysis and prediction unit 53 uses the prediction model generated by the learning unit and predicts the service life of the facility according to the environment where the facility is laid based on the result processed by the data processing unit 52.

[0086] In addition, the second calculation unit 12 may be configured to calculate the service life of the facility without using the prediction model as described above. For example, a dummy sample is arranged near a facility (electric wire) that is actually laid, and is collected after a predetermined period (for example, one year) has elapsed. The second calculation unit 12 may be configured to analyze the collected dummy sample and calculate the service life of the facility (electric wire) laid near where the dummy sample was arranged based on the analysis result. The dummy sample is assumed to be more susceptible to environmental influence and more likely to deteriorate than the laid facility (electric wire).

[0087] Furthermore, as a basis for comparison, the durability period may be presented to the customer by presenting both the information of the electric wire serving as the teacher data and the information of the customer's electric wire. That is, the information of the electric wire serving as the teacher, the surrounding environment information of the electric wire serving as the teacher, the information of the customer's electric wire, or the surrounding environment information of the customer's electric wire may be presented to the customer. For example, the average humidity for one year around the electric wire serving as the teacher and the average humidity for one year around the customer's electric wire may be presented to relatively present the deterioration of the customer's electric wire. That is, it may be quantitatively shown that the humidity is "higher on average per year", "equivalent", or "lower on average per year" than the electric wire serving as the teacher. The surrounding environment information of the electric wire may be inferred from the measurement values of the sensors in the vicinity of the electric wire stored in an external server.

[0088] (Regarding the first operation of the calculation unit) The calculation unit 16 may be configured to determine the accumulation period based on the information indicating the durability period for each type of facility calculated by the second calculation unit 12, and calculate the payment amount based on the accumulation period and the cost related to the replacement of the facility. Hereinafter, the payment amount will be described as the installment accumulation amount.

[0089] FIG. 9 is a diagram schematically showing a typical model of the accumulation amount calculated by the calculation unit 16. FIG. 9(a) is a diagram schematically showing an example of a model for calculating the accumulation amount when the durability period of the facility is 20 years later.

[0090] For example, when the durability period of the facility is 20 years later and the total cost related to the replacement of the facility is set to 120 million yen, the calculation unit 16 calculates the accumulation amount per month as 500,000 yen. Note that the calculation unit 16 may not have a configuration in which the accumulation amount per month is equal. For example, the calculation unit 16 may change the accumulation amount up to the 10th year and the accumulation amount after the 10th year.

[0091] FIG. 9(b) is a diagram schematically showing an example of a model for calculating a reserve fund when the useful life of the equipment is the last 5 years. Also, when the useful life of the equipment is the last 5 years and the total cost of the replacement equipment is set at 120 million yen, the calculation unit 16 calculates the reserve fund at 2 million yen per month. Note that the calculation unit 16 may be configured such that the reserve fund per month is not equal, as described above. For example, the calculation unit 16 may change the reserve fund up to the third year and the reserve fund after the third year.

[0092] Also, after the reserve fund reaches the full amount (total cost of the replacement equipment), due to factors such as soaring fuel costs and labor costs, the cost of transporting the replacement equipment to the site and the cost of installing the replacement equipment may increase. Therefore, as shown in FIGS. 9(a) and 9(b), a configuration may be adopted in which a certain cost is still collected even after the reserve fund reaches the full amount.

[0093] With such a configuration, the management device 1 can receive a part of the cost of the replacement equipment from the customer in advance as a reserve fund on a regular basis, and can manufacture the equipment using this reserve fund as a source of funds. Therefore, it is possible to suppress the manufacturing and storage costs of the equipment by the manufacturing company. Also, the customer company can plan to accumulate the cost of the replacement equipment.

[0094] FIG. 9(c) is a diagram schematically showing an example of a model for calculating a reserve fund when the equipment breaks down before the useful life of the equipment. Even when the equipment breaks down before the useful life of the equipment, since the management device 1 has a reserve fund accumulated until the breakdown, it can settle with the customer company with a small payment, and since it can provide the replacement equipment in a timely manner, it does not affect the operation of the customer company.

[0095] (Regarding the second operation of the calculation unit) The calculation unit 16 may be configured to determine the accumulation period based on the information indicating the service life for each type of facility calculated by the second calculation unit 12, and calculate the payment amount based on the accumulation period and the cost related to the preliminary response before replacement of the replacement facility for the equipment. Hereinafter, the payment amount will be described as the installment payment for installment payment.

[0096] The cost related to the preliminary response before replacement of the replacement facility for the equipment refers to the cost for emergency response or long-term response. In the case of emergency response, an electric wire as an emergency response item that is easy to install or can absorb differences in customer specifications is replaced. This emergency response item enables a quick emergency response by, for example, reducing weight or making it easier to bend by relaxing the current capacity and long-term reliability compared to long-term response items. Also, the period of using the emergency response item is restricted by the amount of power used and the usage time by the customer. Furthermore, during the period of using the emergency response item, a long-term response item with enhanced current capacity and long-term reliability is manufactured. The installment payment may be calculated from the costs required for these initial responses.

[0097] (Regarding the third operation of the calculation unit) The calculation unit 16 may be configured to determine the accumulation period based on the information indicating the service life for each type of facility calculated by the second calculation unit 12, and calculate the payment amount (installment payment) based on the accumulation period and the diagnosis of initial defects at the time of equipment replacement.

[0098] After replacement, in order to diagnose the initial defects of the replaced equipment, it is necessary to install sensors for acquiring the laid environmental information, perform image analysis of the laid equipment, etc. The payment amount (installment payment) may be calculated from the costs required for the diagnosis of initial defects at the time of replacement of these equipment.

[0099] Further, the calculation unit 16 may be configured to calculate the cost related to the replacement of the equipment based on the manufacturing cost of the equipment manufactured by the order of the first ordering unit 15, and recalculate the payment amount based on the calculated cost related to the replacement of the equipment. In the case of this configuration, the presentation unit 17 presents the recalculated payment amount to the customer by the calculation unit 16. Note that the payment amount may be paid in a lump sum or in installments. The money paid in installments is referred to as a savings amount.

[0100] FIG. 10 is a diagram schematically showing an example of a model for calculating the savings amount before and after recalculation. For example, in the case of an electric wire using copper as a raw material, the copper price varies depending on the timing of purchasing copper. Therefore, if copper is purchased during a period when the copper price is low and the electric wire is manufactured, the manufacturing cost of the electric wire can be kept low. Also, the fuel cost and labor cost vary depending on the time. Therefore, if the electric wire is transported and installed during a period when the fuel cost and labor cost are low, the cost of transporting the replacement to the site and the cost of installing the replacement can be kept low.

[0101] For example, as shown in FIG. 10(a), when the useful life of a certain equipment is 20 years and the cost related to the replacement of the equipment (accumulated amount P1) is set to 120 million yen, the monthly savings amount is 500,000 yen.

[0102] Then, when 10 years have passed and the copper price and labor cost have decreased, as shown in FIG. 10(b), the calculation unit 16 re-sets the cost related to the replacement of the equipment (accumulated amount P2) after the 10th year to 100 million yen. Also, since 600 million yen has been accumulated by the 10th year, the remaining amount is 40 million yen. Therefore, the monthly savings amount after the 10th year is approximately 330,000 yen. Note that in the above description, an example in which the savings amount is recalculated at the 10th year for a useful life of 20 years is shown, but the present invention is not limited to this example, and the savings amount may be recalculated at regular intervals (for example, every 3 years, etc.) or at irregular intervals.

[0103] With such a configuration, when the cost related to the replacement of the equipment changes, the management device 1 can recalculate the reserve fund and notify the customer company of the recalculated reserve fund, thereby reducing the burden of the reserve fund on the customer company. Note that the management device 1 may be configured to refund the difference to the customer company when the reserve fund reaches the full amount without changing it within the service life even if the reserve fund is recalculated.

[0104] (Regarding the manufacturing time of the equipment) As shown in FIG. 1, the management device 1 may be configured to include a second determination unit 28 that determines the timing of purchasing materials (raw materials) when manufacturing the equipment. According to this configuration, the first ordering unit 15 instructs to purchase the materials for manufacturing the equipment at the timing determined by the second determination unit 28.

[0105] As described above, in the case of an electric wire using copper as a raw material, the copper price varies depending on the timing of purchasing copper. Therefore, if copper is purchased at a time when the copper price is low and the electric wire is manufactured, the manufacturing price of the electric wire can be kept low.

[0106] The second determination unit 28 determines the timing of purchasing materials (raw materials) when manufacturing the equipment, for example, based on the average value of the copper price over the past N (N is an integer of 1 or more) months. Also, the second determination unit 28 may be configured to determine the timing of purchasing materials (raw materials) when manufacturing the equipment based on the information of a website that predicts the price movement of the copper price.

[0107] (Regarding the first configuration of the two - side platform) As shown in FIG. 1, the management device 1 includes a reception unit 18, a subtraction unit 19, and a second ordering unit 20. The reception unit 18 receives a request for equipment replacement from a customer registered in the first registration unit 11. Specifically, when the reception unit 18 receives a request for equipment replacement from the customer terminal device 3, it accesses the server 2a to read the customer information I1 and confirms that the received customer is registered. Also, when the reception unit 18 receives a replacement request before the service life of the equipment, the calculation unit 16 calculates the payment amount based on the remaining amount.

[0108] The subtraction unit 19 subtracts the number of facilities to be exchanged received by the reception unit 18 from the actual inventory of facilities. Specifically, the subtraction unit 19 accesses the server 2b and updates the table indicating the inventory so as to subtract the number of facilities to be exchanged from the actual inventory of facilities.

[0109] When the second order placement unit 20 receives a facility replacement request from the reception unit 18, it places an order for the replacement of the facility with the construction contractor. Specifically, the second order placement unit 20 places an order with the construction contractor terminal device 4 managed by the construction contractor via the network NW2. The construction contractor receives the facility, transports the facility to the site according to the ordered content, and installs the facility.

[0110] In this way, when the management device 1 receives a replacement request from the customer company, it subtracts the inventory of facilities and also places an order for construction with the contractor who installs the facilities, so that it can perform the intermediary procedure while managing the inventory.

[0111] (Regarding the second configuration of the two - side platform) As shown in FIG. 1, the management device 1 includes a second registration unit 21 and a first determination unit 22. The case where there are multiple construction contractors and the cases where there is one replacement facility and multiple replacement facilities will be described.

[0112] The second registration unit 21 registers at least the information I6 about the construction contractor including information about past construction. Specifically, the second registration unit 21 generates the information I6 about the construction contractor including information on which construction contractor constructed which facility, and saves the information I6 about this construction contractor in the server 2c.

[0113] FIG. 11 is a diagram schematically showing an example of information I6 regarding a construction contractor. The information I6 regarding the construction contractor includes items such as a contractor ID uniquely assigned to the construction contractor, an equipment ID, a construction date indicating the year, month, and day of construction, and an evaluation by the customer (information regarding past construction). The evaluation by the customer is an evaluation by the customer company after construction. Note that the items included in the information I6 regarding the construction contractor are merely examples and are not limited to these items.

[0114] When a plurality of construction contractors are registered and the reception unit 18 receives an exchange request for one piece of equipment, the first determination unit 22 determines the priority order of the construction contractors based on the information regarding past construction included in the information I6 regarding the construction contractor. Specifically, the first determination unit 22 accesses the server 2c, reads out the information I6 regarding the construction contractor, and determines the priority order of the construction contractors for each piece of equipment from past construction records and the like.

[0115] Also, when a plurality of construction contractors are registered and the reception unit 18 receives an exchange request for a plurality of pieces of equipment, the first determination unit 22 determines the priority order of the construction contractors based on the information regarding past construction included in the information I6 regarding the construction contractor, and determines the priority order of the equipment to be constructed based on the information indicating the priority order of the equipment.

[0116] FIG. 12 is a diagram schematically showing an example of information I7 indicating the priority order of equipment. The information I7 indicating the priority order of equipment shows the construction location and the priority order.

[0117] When a plurality of construction contractors are registered and the reception unit 18 receives an exchange request for one piece of equipment, the second ordering unit 20 selects a construction contractor based on the priority order of the construction contractors determined by the first determination unit 22, and orders the selected construction contractor to exchange the equipment.

[0118] In addition, the second ordering unit 20 has a plurality of construction contractors registered therein. When the reception unit 18 receives a replacement request for a plurality of facilities, the second ordering unit 20 selects a construction contractor based on the priority order of the construction contractors determined by the first determination unit 22, and orders the selected construction contractor to replace the facilities determined based on the priority order of the facilities determined by the first determination unit 22.

[0119] In this way, when there are a plurality of construction contractors, the management device 1 determines the construction contractors based on the priority order based on the past construction performance of the construction contractors. Therefore, since the construction contractors are determined based on the past construction performance and evaluation, etc., by applying the management device 1, the construction contractors who perform solid construction will have a higher evaluation and can continuously receive orders.

[0120] In addition, when there are a plurality of facilities to be replaced, the management device 1 preferentially selects the facilities with a higher priority. Therefore, the management device 1 can give top priority to the construction of the facilities at the locations with a higher priority.

[0121] Next, the case where there is only one construction contractor and the case where there is one replacement facility and the case where there are a plurality of replacement facilities will be described. The second registration unit 21 registers information I6 regarding a construction contractor including at least information regarding past construction. When there is only one construction contractor registered and the reception unit 18 receives a replacement request for one facility, the first determination unit 22 determines the construction contractor.

[0122] In addition, when there is only one construction contractor registered and the reception unit 18 receives a replacement request for a plurality of facilities, the first determination unit 22 determines the construction contractor and determines the priority order of the facilities to be constructed based on the information indicating the priority order of the facilities.

[0123] When there is only one construction contractor registered and the reception unit 18 receives a replacement request for one facility, the second ordering unit 20 orders the construction contractor determined by the first determination unit 22 to replace the facility.

[0124] In addition, the second ordering unit 20 has only one registered construction contractor. When the reception unit 18 receives replacement requests for a plurality of facilities, it orders the construction contractor determined by the first determination unit 22 to replace the facilities determined based on the priority order of the facilities determined by the first determination unit 22.

[0125] In this way, when there is only one construction contractor and there are a plurality of facilities to be replaced, the management device 1 preferentially selects the facilities with higher priority and places an order with this construction contractor. Therefore, the management device 1 can give top priority to the construction of the facilities in the location with higher priority.

[0126] (Regarding the third configuration of the two - side platform) As shown in FIG. 1, the management device 1 includes a notification unit 23, a first reception unit 24, a first transmission unit 25, a second reception unit 26, and a second transmission unit 27.

[0127] When the reception unit 18 receives a facility replacement request, the notification unit 23 selects a plurality of construction contractors based on the priority order of the construction contractors determined by the first determination unit 22, and notifies the selected plurality of construction contractors of the construction specifications. Specifically, the notification unit 23 notifies (sends) the construction specifications to the construction contractor terminal devices 4 managed by the selected plurality of construction contractors via the network NW2.

[0128] The first reception unit 24 receives estimates from a plurality of construction contractors. The construction contractor confirms the content of the construction specifications, creates an estimate for the construction work, and transmits the estimate created using the construction contractor terminal device 4 to the management device 1.

[0129] The first transmission unit 25 transmits the estimate to the customer who has received the facility replacement request by the reception unit 18. The customer examines the content of the received estimate and selects one construction contractor.

[0130] The second receiving unit 26 receives the selection result by the customer who has received the estimate sent by the first transmitting unit 25. The second transmitting unit 27 transmits the selection result to a plurality of construction contractors who have received the estimate by the first receiving unit 24. The second transmitting unit 27 also transmits the selection result to the construction contractors who have not been selected. The second ordering unit 20 orders the replacement of the equipment to the construction contractor selected by the customer based on the selection result.

[0131] In this way, when the management device 1 receives an order for equipment construction from a customer, based on the priority, it transmits the construction specification to a plurality of construction contractors, transmits the estimate received from each construction contractor to the customer, and orders the replacement of the equipment to the construction contractor selected by the customer. Therefore, the customer can select a preferred construction contractor from among the plurality of construction contractors selected based on the priority.

[0132] (Regarding the configuration of having an inventory of power transmission lines for backward compatibility) Here, if an inventory of power transmission lines different for each specification is held, the inventory quantity increases. The power transmission line is a concept that includes uncoated wires such as bare wires and insulated wires, CV (cross-linked polyethylene insulated vinyl sheath cable) cables, OF (Oil-filled cable) cables, etc. A CV cable is a power cable that uses cross-linked polyethylene as an insulating material. An OF cable is a cable in which a passage for insulating oil is provided in the cable, and an appropriate hydraulic pressure is applied by a gravity tank or pressure tank provided at the end to prevent the generation of bubbles due to temperature changes. Also, when comparing a CV cable and an OF cable, which are types of power transmission lines, the CV cable is a higher-level cable.

[0133] Also, the specifications of the power transmission line include size (thickness), type, allowable current, allowable voltage, etc. The size differs between single wires and stranded wires. The size of the stranded wire is, for example, 400 sq (cross-sectional area of 400 mm 2 ), 250 sq (cross-sectional area of 250 mm 2 ), 200 sq (cross-sectional area of 200 mm 2) etc. Also, the larger the size of the power transmission line, the higher the specification. In the above example, in order of higher specification, 400 sq (cross-sectional area is 400 mm 2 ), 250 sq (cross-sectional area is 250 mm 2 ), 200 sq (cross-sectional area is 200 mm 2 ). The allowable current is, for example, 7 A, 12 A, 17 A, etc. according to the size of the power transmission line. Also, the larger the size of the power transmission line, the greater the allowable power. The allowable voltage is about 600 V to 500 kV. Also, the higher the voltage that can be transmitted on the power transmission line, the higher the specification. Also, the power transmission lines are upward compatible. That is, a 400 sq power transmission line can be used as an alternative to a 250 sq power transmission line.

[0134] For example, if a power transmission line with a large size (hereinafter referred to as an upper transmission line) is prepared, it can be applied not only to a power transmission line with the same large size but also to a power transmission line with a small size (hereinafter referred to as a lower transmission line). Therefore, if the upper transmission line is held, the inventory quantity can be suppressed. Also, when connecting power transmission lines with different specifications, a connector called a different type connection part is used.

[0135] On the other hand, the upper transmission line is more expensive than the lower transmission line. Therefore, as described above, when changing from the lower transmission line to the upper transmission line during the replacement of the power transmission line, it causes a price increase (upgrade) and the cost of replacement increases.

[0136] Therefore, while holding inventory in the upper transmission line, a power transmission line with specifications suitable for replacement is manufactured at an appropriate timing (for example, a timing before the replacement date based on the service life). For example, in the case of operation based on the service life (that is, when replacement does not occur before the service life), since a power transmission line with the same specifications as the power transmission line in use can be prepared, replacement can be performed without causing an upgrade. Further, if the power transmission line in use is damaged and replacement is necessary before the service life, by utilizing the upper transmission line in inventory, although an upgrade will occur, the impact on the operation of the customer company can be suppressed.

[0137] The specific configuration and operation will be described below. The facility is a power transmission line for transmitting power. There are multiple specifications for the power transmission line. The second calculation unit 12 calculates the service life for each specification of the power transmission line based on the information on the facility included in the customer information or by using a prediction model generated based on the information on the facility provided by an external device and based on the information on the facility included in the customer information.

[0138] For example, the second calculation unit 12 calculates the service life of the 400 sq power transmission line, 250 sq power transmission line, and 200 sq power transmission line for all customers respectively.

[0139] The first calculation unit 13 obtains the total number for each specification of the power transmission line based on the information on the facility included in the customer information, and calculates the first inventory quantity for each specification of the power transmission line based on the total number and the service life for each specification of the power transmission line calculated by the second calculation unit 12.

[0140] For example, the first calculation unit 13 calculates that the inventory quantity of the 400 sq power transmission line is "20 pieces", the inventory quantity of the 250 sq power transmission line is "50 pieces", and the inventory quantity of the 200 sq power transmission line is "200 pieces".

[0141] The determination unit 14 compares the first inventory quantity calculated by the first calculation unit 13 with the actual inventory quantity of the power transmission line, and determines whether the actual inventory quantity of the power transmission line is insufficient.

[0142] When it is determined by the determination unit 14 that the inventory of the actual power transmission line is insufficient, the first ordering unit 15 calculates the replacement date from the service life for each specification of the power transmission line calculated by the second calculation unit 12, calculates the manufacturing start date considering the time required for manufacturing the power transmission line from the replacement date, and orders the manufacturing of the power transmission line based on the manufacturing start date.

[0143] For example, when the service life of the 250 sq power transmission line calculated by the second calculation unit 12 is 25 years, the first ordering unit 15 calculates the replacement date as "December 10, 2020" based on the construction date (December 10, 1995). When the time required for manufacturing the power transmission line is 6 months, the first ordering unit 15 orders the manufacturing of the 250 sq power transmission line on "June 10, 2020".

[0144] Also, as described above, a power transmission line (upper transmission line) composed of a higher specification is compatible with a power transmission line (lower transmission line) composed of a lower specification. The first inventory includes at least one power transmission line composed of a higher specification. The higher specification means that the allowable voltage that can be transmitted by the power transmission line is large, the size of the power transmission line is large, or the type of the power transmission line is higher. The types of power transmission lines include OF cables, CV cables with a water-blocking layer, CV cables without a water-blocking layer, etc. When connecting these cables with different types, they are connected by a heterogeneous connection part. The first inventory also includes heterogeneous connection parts (at least two) for connecting a power transmission line composed of a higher specification and a lower power transmission line.

[0145] With such a configuration, the management device 1 manufactures a power transmission line with a specification suitable for replacement at an appropriate timing (for example, a timing before the replacement date based on the service life) while holding inventory in the upper power transmission line. Therefore, in the case of operation based on the service life, a power transmission line with the same specification as the power transmission line in use can be prepared, so that replacement can be performed without causing an upgrade. Also, if the power transmission line in use is damaged and replacement is necessary before the service life, although an upgrade will occur by utilizing the upper power transmission line in inventory, the impact on the operation of the customer company can be suppressed.

[0146] Also, when the manufacturing start date of other power transmission lines has not yet arrived, there may be a case where there is only one upper transmission line in inventory. Therefore, the cost for the manufacturing company to store the equipment can be further suppressed.

[0147] (Regarding the management method) Next, a management method for suppressing the impact on the operation of the customer company and suppressing the costs for the manufacturing and storage of equipment by the manufacturing company will be described. FIG. 13 is a flowchart showing the procedure of the management method.

[0148] In step ST1, the first registration unit 11 registers customer information I1 including at least information on the equipment used by the customer (first registration step).

[0149] In step ST2, the first calculation unit 13 obtains the total number for each type of equipment based on the information on the equipment included in the customer information I1, and calculates the first inventory number for each type of equipment based on the total number (first calculation step).

[0150] In step ST3, the determination unit 14 compares the first inventory number calculated in the first calculation step with the actual inventory number of the equipment, and determines whether the actual inventory number of the equipment is insufficient (determination step).

[0151] In step ST4, when it is determined in the determination process that the actual inventory of equipment is insufficient, the first ordering department 15 places an order for the production of the insufficient equipment (first ordering process).

[0152] In step ST5, the calculation unit 16 calculates the payment amount based on the cost of the equipment substitutes for each customer registered in the first registration process (calculation process).

[0153] In step ST6, the presentation unit 17 presents the payment amount calculated in the calculation process to the customer (presentation process).

[0154] In this way, since the management method can receive payments related to equipment from customers in advance and use this payment as a source of funds to manufacture equipment, it is possible to suppress the costs of equipment manufacturing and storage by the manufacturing company.

[0155] Also, when it is determined in the determination process that the actual inventory of equipment is insufficient, the management method places an order for the production of equipment in the first ordering process, so it is possible to secure a certain amount of inventory and suppress the impact on the operation of the customer company due to inventory shortages.

[0156] (Regarding the management program) The management program that suppresses the impact on the operation of the customer company and suppresses the costs for equipment manufacturing and storage by the manufacturing company mainly consists of the following processes and is executed by a computer 500 (hardware).

[0157] Process 1: A process of registering customer information I1 including at least information on the equipment used by the customer Process 2: A process of obtaining the total number for each type of equipment based on the information on the equipment included in the customer information I1 and calculating the first inventory number for each type of equipment based on the total number Process 3: A process of comparing the first inventory number calculated in the first calculation process with the actual inventory of equipment and determining whether the actual inventory of equipment is insufficient Step 4: If it is determined in Step 3 that the actual inventory of equipment is insufficient, place an order for the manufacture of the insufficient equipment Step 5: For each customer registered in Step 1, calculate the payment amount based on the cost of the replacement equipment Step 6: Present the accumulated amount calculated in Step 5 to the customer

[0158] Here, the configuration and operation of the computer 500 will be described with reference to the drawings. FIG. 14 is a diagram showing the configuration of the computer 500. As shown in FIG. 14, the computer 500 is configured by connecting a processor 501, a memory 502, a storage 503, an input / output I / F 504, and a communication I / F 505 on a bus A. Through the cooperation of these components, the functions and / or methods described in the present disclosure are realized.

[0159] A display and a pointing device (e.g., a mouse or a keyboard) are connected to the input / output I / F 504. The communication I / F is an interface compliant with a predetermined communication standard and communicates with devices (e.g., the customer terminal device 3 and the construction contractor terminal device 4) via the network NW1 and the network NW2, either wired or wirelessly. The communication I / F corresponds to the presentation unit 17, the reception unit 18, the notification unit 23, the first reception unit 24, the first transmission unit 25, the second reception unit 26, and the second transmission unit 27.

[0160] The memory 502 is composed of a RAM (Random Access Memory). The RAM is composed of a volatile memory or a non-volatile memory.

[0161] The storage 503 is composed of a ROM (Read Only Memory). The ROM is composed of a non-volatile memory and is realized, for example, by an HDD (Hard Disc Drive) or an SSD (Solid State Drive). The storage 503 corresponds to the server 2 described above. Various programs such as the management program realized in the above-described Steps 1 to 6 are stored in the storage 503.

[0162] For example, the processor 501 controls the overall operation of the computer 500. The processor 501 is an arithmetic unit that loads an operating system and various programs for realizing various functions from the storage 503 into the memory 502 and executes the instructions included in the loaded programs.

[0163] Specifically, when the processor 501 receives a user operation, it reads out a program (for example, the management program according to the present invention) stored in the storage 503, expands the read program in the memory 502, and executes the program. Further, when the processor 501 executes the management program, the functions of the first registration unit 11, the second calculation unit 12, the first calculation unit 13, the determination unit 14, the first order placement unit 15, the calculation unit 16, the subtraction unit 19, the second order placement unit 20, the second registration unit 21, the first determination unit 22, and the second determination unit 28 are realized.

[0164] Here, the configuration of the processor 501 will be described. The processor 501 is realized by, for example, a CPU (Central Processing Unit), an MPU (Micro Processing Unit), a GPU (Graphics Processing Unit), various other arithmetic units, or a combination thereof.

[0165] Further, in order to realize the functions and / or methods described in the present disclosure, a part or all of the functions such as the processor 501, the memory 502, and the storage 503 may be configured by a processing circuit 601 which is dedicated hardware. FIG. 15 is a diagram showing the configuration of the processing circuit 601 of the computer 600. The processing circuit 601 is, for example, a single circuit, a composite circuit, a programmed processor, a parallel programmed processor, an ASIC (Application Specific Integrated Circuit), an FPGA (Field-Programmable Gate Array), or a combination thereof.

[0166] Also, although the processor 501 has been described as a single component, it is not limited to this, and it may be composed of a set of a plurality of physically separate processors. In this specification, the program described as being executed by the processor 501 or the instructions included in the program may be executed by a single processor 501, or may be executed distributively by a plurality of processors. Further, the program executed by the processor 501 or the instructions included in the program may be executed by a plurality of virtual processors.

[0167] In this way, by executing the management program on the computers 500 and 600, it is possible to receive payment for the equipment from the customer in advance and use this payment as a capital to manufacture the equipment, so that the costs of manufacturing and storing the equipment by the manufacturing company can be suppressed.

[0168] Also, by executing the management program on the computers 500 and 600, when it is determined in step 3 (determination step) that the actual inventory of the equipment is insufficient, an order for manufacturing the equipment is placed in step 4 (first ordering step), so that a certain inventory can be secured and the impact on the operation of the customer company due to inventory shortage can be suppressed.

[0169] As described above, some embodiments of the present application have been described in detail based on the drawings, but these are examples, and the present invention can be implemented in other forms in which various modifications and improvements are made based on the knowledge of those skilled in the art, including the aspects described in the disclosure column of the present invention.
