Summary of the Invention

Problems to be Solved by the Invention

[0004] However, since the invention of Patent Document 1 calculates the planned value from the average of the actual values, for example, when there is a chronic delay from past actual results, it becomes difficult to confirm the occurrence of delays in the actual results of the comparison target, and accurate evaluation cannot be performed.

[0005] The present invention has been made in view of such circumstances. The purpose is to accurately evaluate whether the actual value of the lead time is appropriate.

Means for Solving the Problems

[0006] To solve the above problems, the invention of claim 1 is an automatic appropriate lead time calculation device 10, which, for example as shown in Figures 1 to 8, includes an acquisition unit 113 that acquires the standard lead time for each process related to design work and construction work, the addition or subtraction value of the lead time in the process corresponding to the design conditions and construction conditions, and the actual value of the adoption rate of the design conditions and construction conditions, and the actual value of the adoption rate of the design conditions and construction conditions acquired by the acquisition unit 113 in the process corresponding to the design conditions and construction conditions Lead time The system includes a calculation unit 111 that calculates an appropriate lead time 251b by adding or subtracting a predetermined value obtained by multiplying the addition or subtraction value to the standard lead time of the corresponding process.

[0007] According to the invention described in claim 1, the appropriate lead time 251b is calculated by weighting the adjustment values ​​according to the design conditions or construction conditions based on the actual adoption rates of the design conditions and construction conditions, and then adding or subtracting these values ​​from the standard lead time of the corresponding process. Therefore, the actual lead time can be compared with the appropriate lead time 251b calculated based on the actual adoption rates of the design conditions and construction conditions that increase or decrease the required lead time, making it possible to evaluate more accurately whether the actual lead time is appropriate.

[0008] The invention described in claim 2 is, for example, the appropriate lead time automatic calculation device 10 described in claim 1, as shown in Figure 1, wherein the acquisition unit 113 acquires actual values ​​of the adoption rate of a portion of a predetermined group.

[0009] According to the invention described in claim 2, for example, data from only a predetermined location can be acquired, and a more accurate optimal lead time 251b can be calculated.

[0010] The invention described in claim 3 is, for example, as shown in Figure 1, an automatic appropriate lead time calculation device 10 according to claim 1 or 2, wherein the acquisition unit 113 acquires actual values ​​of a portion of the adoption rate over a predetermined period.

[0011] According to the invention described in claim 3, for example, it is possible to exclude data that is too old, and to calculate a more accurate appropriate lead time 251b.

[0012] The invention described in claim 4 is, for example, as shown in Figures 1 to 3, an appropriate lead time automatic calculation device 10 according to claim 1 or 2, comprising: a storage unit 12 having a standard lead time database 121 in which the standard lead time is stored and a standard condition database 122 in which the adjustment values ​​are stored; and a setting unit 112 capable of changing the standard lead time in the standard lead time database 121 and / or the adjustment values ​​in the standard condition database 122.

[0013] According to the invention described in claim 4, the standard lead time in the standard lead time database 121 and / or the addition / subtraction values ​​in the standard condition database 122 can be changed depending on the location where it is installed. Therefore, the automatic appropriate lead time calculation device 10 can be operated flexibly according to the location where it is installed and the users who use it.

[0014] The invention described in claim 5 is, for example, as shown in Figures 1 and 7, an appropriate lead time automatic calculation device 10 as described in claim 1 or 2, wherein the acquisition unit 113 acquires actual values ​​of the lead time required for design work and construction work, and includes a display control unit 114 that compares and displays the actual values ​​of the lead time acquired by the acquisition unit 113 with the appropriate lead time 251b calculated by the calculation unit 111.

[0015] According to the invention described in claim 5, by comparing and displaying the actual lead time with the appropriate lead time 251b, problems in the business process can be visualized more clearly, making it easier to consider future improvement plans.

[0016] The invention described in claim 6 is, for example, as shown in Figure 1, an automatic appropriate lead time calculation system 100 comprising an automatic appropriate lead time calculation device 10 according to claim 1 or 2, and a user terminal 20 that transmits a calculation instruction for the appropriate lead time 251b to the automatic appropriate lead time calculation device 10.

[0017] According to the invention described in claim 6, each user can calculate an appropriate lead time 251b via their own user terminal 20 and compare it with their actual lead time.

[0018] The invention described in claim 7 is, for example, as shown in Figures 1 to 8, an automatic method for calculating appropriate lead time using an automatic appropriate lead time calculation device, comprising acquisition steps S1 and S2 for acquiring the standard lead time for each process related to design work and construction work, the addition or subtraction value of the lead time in the process corresponding to the design conditions and construction conditions, and the actual value of the adoption rate of the design conditions and construction conditions, and the actual value of the adoption rate of the design conditions and construction conditions acquired in acquisition steps S1 and S2 for the process corresponding to the design conditions and construction conditions Lead time The system includes a calculation step S5 in which a predetermined value obtained by multiplying the addition / subtraction value is added to or subtracted from the standard lead time of the corresponding process to calculate the appropriate lead time 251b.

[0019] According to the invention described in claim 7, the appropriate lead time 251b is calculated by weighting the adjustment values ​​according to the design conditions or construction conditions based on the actual adoption rates of the design conditions and construction conditions, and then adding or subtracting these values ​​from the standard lead time of the corresponding process. Therefore, the actual lead time can be compared with the appropriate lead time 251b calculated based on the actual adoption rates of the design conditions and construction conditions that increase or decrease the required lead time, allowing for a more accurate evaluation of the actual lead time.

[0020] The invention according to claim 8 is a program, for example, as shown in FIGS. 1 to 8, which causes a computer of the appropriate lead time automatic calculation device 10 to obtain the standard lead time for each process related to the design work and the construction work, the addition and subtraction value of the lead time in the process corresponding to the design conditions and the construction conditions, and the actual value of the adoption ratio of the design conditions and the construction conditions. An acquisition unit 113, and the actual value of the adoption ratio of the design conditions and the construction conditions acquired by the acquisition unit 113 is multiplied by the addition and subtraction value in the process corresponding to the design conditions and the construction conditions to obtain a predetermined value, which is added to or subtracted from the standard lead time of the corresponding process, and functions as a calculation unit 111 that calculates the appropriate lead time 251b. Lead time It functions as a calculation unit 111 that adds to or subtracts from the standard lead time of the corresponding process the predetermined value obtained by multiplying the actual value of the adoption ratio of the design conditions and the construction conditions by the addition and subtraction value in the process corresponding to the design conditions and the construction conditions to calculate the appropriate lead time 251b.

[0021] According to the invention described in claim 8, the computer calculates the appropriate lead time 251b by weighted-averaging the addition and subtraction values corresponding to the design conditions or the construction conditions based on the actual values of the adoption ratios of the design conditions and the construction conditions, and then adding to or subtracting from the standard lead time of the corresponding process. Therefore, it is possible to compare the actual value of the lead time with the appropriate lead time 251b calculated based on the actual adoption of the design conditions and the construction conditions that increase or decrease the required lead time, and it becomes possible to more accurately grasp the actual value of the lead time.

Effect of the Invention

[0022] According to the present invention, it is possible to more accurately evaluate whether the actual value of the lead time is appropriate.

Brief Description of the Drawings

[0024] Hereinafter, an automatic lead time calculation device according to an embodiment of the present invention will be described in detail with reference to the drawings. However, the scope of the invention is not limited to the illustrated example. In the following description, components having the same function and configuration will be denoted by the same reference numerals, and their descriptions will be omitted.

[0025] [Overall Configuration of the Automatic Calculation System for Optimal Lead Time] Figure 1 shows the overall configuration of the appropriate lead time automatic calculation system (hereinafter referred to as the system) 100 according to the present invention. For example, the system 100 comprises a server 10, which is an appropriate lead time automatic calculation device, and a user terminal 20. The server 10 and the user terminal 20 are connected to each other by a network N.

[0026] Network N may include various communication network lines such as telephone lines, fiber optics, mobile communication networks, satellite communication lines, CATV (Community Antenna Television) lines, or other dedicated lines, as well as Internet service providers (i.e., the Internet) that connect them. Network N may also be a collective communication network in which various communication networks such as LAN (Local Area Network), WAN (Wide Area Network), WiFi (Wireless Fidelity), Bluetooth (registered trademark), or NFC (Near Field Communication) are connected in a manner that enables communication with each other. Furthermore, the form of connection may be wired, wireless, or a mixture of wired and wireless.

[0027] (server) Server 10 is provided at each location to which each user of System 100 belongs. Server 10 is equipped with the necessary functions for System 100. In this embodiment, Server 10 comprises a control unit 11, a storage unit 12, and a communication unit 13. The various parts of Server 10 are connected by a bus 14.

[0028] The server 10 may be provided as a physical device or as an inanimate object in a cloud environment. Furthermore, if the server 10 is provided as a physical device, it may be equipped with a publicly known display unit and operation unit so that various processes can be performed in the vicinity of the server 10.

[0029] {control unit} The control unit 11 consists of a CPU (Central Processing Unit), RAM (Random Access Memory), and other components. The CPU reads various programs stored in the memory unit 12, loads them into the RAM, executes various processes according to the loaded programs, and centrally controls the operation of each part of the server 10.

[0030] In particular, the control unit 11 functions as a calculation unit 111, a setting unit 112, an acquisition unit 113, and a display control unit 114 when the CPU executes a program.

[0031] <Calculation Section> The calculation unit 111 calculates the appropriate lead time 251b (see Figure 7) based on the standard lead time for each process obtained by the acquisition unit 113 from the standard lead time database 121, the adjustment values ​​obtained from the standard condition database 122, and the adoption rates of each design condition and construction condition obtained from the actual condition database 124, in response to instructions received from the user terminal 20. The details of this automatic calculation process for the appropriate lead time by the calculation unit 111 will be described later.

[0032] <Setting Section> The setting unit 112 sets (changes) the standard lead time in the standard lead time database 121 and the addition / subtraction values ​​in the standard condition database 122 in accordance with instructions received from the user terminal 20.

[0033] <Acquisition Department> The acquisition unit 113 acquires the necessary data from various databases stored in the storage unit 12, as described above, in response to instructions received from the user terminal 20.

[0034] <Display Control Section> The display control unit 114 transmits a display control signal to the user terminal 20, causing the display unit 25 of the user terminal 20 to display the desired information.

[0035] {Storage section} The storage unit 12 includes an HDD (Hard Disk Drive) and non-volatile semiconductor memory, etc. The storage unit 12 stores various programs and data executed by the control unit 11. At least a portion of the various programs may be stored in the ROM (Read Only Memory) of the control unit 11. The storage unit 12 also stores a standard lead time database 121, a standard condition database 122, an actual lead time database 123, and an actual condition database 124.

[0036] <Standard Lead Time Database> As shown in Figure 2, the standard lead time database 121 stores standard lead times, which are the standard lead times required to complete each stage of the design and construction process.

[0037] <Standard Conditions Database> As shown in Figure 3, the standard conditions database 122 stores each design condition and construction condition with associated additions or subtractions of lead time for the corresponding process. For example, in the example in Figure 3, if "Subdivision" is set as the design condition for the item "Contract Category" and "Planning" is set as the design condition for "Product," it indicates that predetermined values ​​E and G are added to or subtracted from the lead time required to complete the "Contract ~ Plan Confirmation" process.

[0038] Although not shown in Figure 3, the design and construction conditions set in the standard conditions database 122 to adjust the lead time of the corresponding process according to the settings include, for example, whether the contract is for individual sales or condominiums, whether it is a free product or a planned product, whether it is three stories or less, whether there is storage and skip-level construction, whether it is a detached house or not, whether the use is a private residence, an apartment building or a row house, whether it is a single-family home or a multi-family home, whether the wall panel length is above a specified value, whether the floor area of ​​the components is above a specified value, whether the price per tsubo is above a specified value, whether the fire resistance classification is fire-resistant according to ministerial ordinance, whether it is a snowy region or not, whether demolition is required, whether ground reinforcement is required, and the delivery method.

[0039] Furthermore, the standard lead time in the standard lead time database 121 and the adjustment values ​​in the standard condition database 122 may, in their initial state, be the standard values ​​of the company that introduced the system 100. However, these values ​​generally differ depending on the location where the system 100 is operated. Therefore, these values ​​may be appropriately set (changed) by the setting unit 112 depending on the location where it is operated. Of course, these values ​​may also be set from scratch by the setting unit 112.

[0040] <Actual Lead Time Database> As shown in Figure 4, the Actual Lead Time Database 123 stores the actual lead times 251a, which are the actual lead times required for each stage of the design and construction work in each project. The Actual Lead Time Database 123 also stores the average lead time required for each stage, based on each actual lead time 251a.

[0041] <Performance Condition Database> As shown in Figure 5, the performance conditions database 124 stores the design conditions and construction conditions set for each project. The performance conditions database 124 also stores the adoption rate of each design condition and construction condition based on the data.

[0042] Furthermore, the actual lead time database 123 and the actual conditions database 124 may be a single database if their primary keys are the same, as shown in Figures 4 and 5.

[0043] {Communications Department} Returning to Figure 1, the communication unit 13 is composed of communication modules and the like. The communication unit 13 sends and receives various signals and data to and from the user terminal 20 connected via the network N. Furthermore, the information sent from the communication unit 13 to the user terminal 20 can be transmitted with multiple pieces of information linked together.

[0044] (User terminal) User terminal 20 is a terminal device owned and used by each user, such as a desktop PC. Note that user terminal 20 may also be a portable information terminal such as a smartphone, tablet, or laptop computer (so-called notebook computer, ultrabook, etc.).

[0045] Each user terminal 20 communicates data to the server 10 using the network N (specifically, the communication line of the user terminal 20 or a wireless LAN, etc.). The user terminal 20 includes a control unit 21, a storage unit 22, a communication unit 23, an input unit 24, and a display unit 25, etc. The various parts of the user terminal 20 are connected by a bus 26.

[0046] {control unit} The control unit 21 is a processor (computer) that includes a CPU, ROM, RAM, etc., and comprehensively controls the operation of each part of the user terminal 20. The CPU reads programs such as applications stored in the memory unit 22, loads them into RAM, and executes various processes by running those programs.

[0047] {Storage section} The storage unit 22 is equipped with non-volatile semiconductor memory and stores programs such as applications, as well as various data. The user terminal 20 also has a web browser or program installed that can display the lead time comparison screen 251 (see Figure 7, described later).

[0048] {Communications Department} The communication unit 23 is composed of a communication interface and the like. The communication unit 23 sends and receives data to and from the server 10 via the network N using a predetermined communication protocol.

[0049] {Input section} The input unit 24 receives operation input from the user. The input unit 24 transmits an operation signal to the control unit 21 in accordance with the operation input. The input unit 24 is equipped with an input device such as a keyboard, mouse, or physical buttons.

[0050] {Display section} The display unit 25 is equipped with a display device such as a liquid crystal display. The display unit 25 displays various information screens, etc., under the control of the control unit 21. The input unit 24 and the display unit 25 may be integrated with a display device such as a liquid crystal panel and an input device such as a touch panel superimposed on the display screen of the display device.

[0051] [Lead time comparison process] An example of the operation of the lead time comparison process, including the automatic calculation of appropriate lead times, by the system 100 described above will be explained using the flowchart shown in Figure 6. The lead time comparison process is started based on an execution instruction from the user terminal 20 to the server 10.

[0052] Upon receiving an instruction to execute the lead time comparison process, the control unit 11 first acquires the actual lead time values ​​(step S1). For example, the acquisition unit 113 acquires the average value for a predetermined location from the actual lead times 251a stored in the actual lead time database 123 as the actual lead time value.

[0053] Next, the acquisition unit 113 acquires the adoption rates of each design condition and construction condition, which have been previously stored in the performance condition database 124, as actual values ​​of the adoption rates (step S2). Then, the acquisition unit 13 acquires the affiliation information of the user from the user terminal 20 that has received an instruction to execute the lead time comparison process, and based on this affiliation information, acquires the adoption rate at a predetermined location from the actual values ​​of the adoption rates acquired in step S2 (step S3).

[0054] Next, the calculation unit 111 calculates a predetermined weighted average (weighted) value by multiplying the adoption rate of each design condition and construction condition at a predetermined site, which was acquired by the acquisition unit 113 in step S3, by the corresponding addition / subtraction values ​​of the process acquired by the acquisition unit 113 from the standard condition database 122 (step S4). Then, the calculation unit 111 calculates the appropriate lead time 251b by adding or subtracting the calculated predetermined value to the standard lead time of each corresponding process stored in the standard lead time database 121 (step S5). Steps S2 and S5 constitute the automatic calculation process for the appropriate lead time.

[0055] As a concrete example, we will explain based on the case of calculating the appropriate lead time 251b for the "contract to plan confirmation" process. In this example, we will assume that the actual values ​​for the adoption rate of "contract work" and "subdivision" in the performance condition database 124 at a designated location, obtained in step S3, are 60%.

[0056] The calculation unit 111 calculates a predetermined value α (0.6 × E = α) by multiplying the adoption rate of "condominiums" (0.6) in the standard condition database 122 shown in Figure 3 by the addition / subtraction value "E" for the "contract ~ plan finalization" process corresponding to the design condition.

[0057] The calculation unit 111 then adds the calculated predetermined value α to the standard lead time "A" for the "contract to plan confirmation" process stored in the standard lead time database 121 shown in Figure 2. By performing the same process for other design conditions, the appropriate lead time 251b for the "contract to plan confirmation" process is calculated. Note that any decimal values ​​may be rounded up or otherwise processed as per the calculation unit 111.

[0058] When the calculation unit 111 calculates the appropriate lead time 251b, the display control unit 114 displays a lead time comparison screen 251 on the display unit 25 of the user terminal 20, as shown in Figure 7. This screen compares the actual lead time value acquired by the acquisition unit 113 in step S1 with the appropriate lead time 251b calculated by the calculation unit 111 in step S3 (step S6). The user compares the displayed actual lead time value and the appropriate lead time 251b. For example, if the actual lead time value is larger and a delay has occurred, the user considers the cause and possible solutions.

[0059] [Summary, Others] Although the above description focused on the application of the present invention to design work, the present invention can be applied substantially similarly to construction work.

[0060] According to the system 100 described above, a predetermined value obtained by multiplying the actual adoption rate of design conditions and construction conditions by the addition / subtraction values ​​in the process corresponding to those design conditions and construction conditions is added to or subtracted from the standard lead time of the corresponding process, and the appropriate lead time 251b is calculated from the sum of the lead times after the addition / subtraction process. Therefore, it is possible to compare the appropriate lead time 251b, which is calculated based on the actual adoption rate of design conditions and construction conditions that increase or decrease the required lead time, with the actual lead time value, and to evaluate more accurately whether the actual lead time value is appropriate.

[0061] Furthermore, according to the system 100 of this embodiment, the number of days spent on design and construction work can be evaluated more accurately, leading to improvements in work processes. This enables design and construction personnel to work within a manageable timeframe, creating opportunities for decent work. Therefore, it can contribute to achieving the Sustainable Development Goals (SDGs) (Goal 8).

[0062] In the above example, a configuration in which one server 10 comprises a control unit 11 and a storage unit 12 was used, but the server is not limited to this. That is, the server 10 is not limited to a single device, but may be configured by connecting multiple devices to each other.

[0063] Furthermore, although the above example illustrates a configuration in which input is received from the user terminal 20, the server 10 may also be equipped with an operation input unit and a display unit, allowing the user to input directly.

[0064] Furthermore, although the above example illustrates a case where system 100 consists of a server 10 and a user terminal 20, it is not limited to this. That is, system 100 may consist of a single user terminal 20 comprising a control unit 21 that functions as a calculation unit 111, a setting unit 112, an acquisition unit 113, and a display control unit 114, and a storage unit 22 equipped with a standard lead time database 121, a standard condition database 122, an actual lead time database 123, and an actual condition database 124. In this configuration, it is not necessary to have an actual condition database 124 in which the design conditions and construction conditions adopted in a series of design and construction operations are stored in association with each project; it is sufficient if the adoption rate of the design conditions and construction conditions at a predetermined point in time is stored in the storage unit 22. Alternatively, the display control unit 114 may display an adoption rate input screen 252 on the display unit 25, which has an input unit 252a into which actual values ​​of the adoption rate of the design conditions and construction conditions can be input, as shown in Figure 8. On the adoption rate input screen 252, the acquisition unit 113 acquires the actual value of the adoption rate calculated by the user and entered into the input unit 252a. Based on this actual value, the calculation unit 113 sequentially calculates predetermined values ​​and appropriate lead times 251b, and the display control unit 114 displays these calculated values.

[0065] Furthermore, while the setting unit 112 is described above as being able to change the standard lead time and adjustment values, it is not limited to this. That is, the setting unit 112 may also be able to change various settings in the standard condition database 122, such as whether any design condition or construction condition is related to the lead time of any process.

[0066] Furthermore, Figure 3 illustrates a configuration in which the standard condition database 122 adds or subtracts a predetermined value from the standard lead time of the corresponding process only when one of the design conditions is selected; in other words, the standard lead time in the standard lead time database 121 is the lead time when the other of the design conditions is selected, but the system is not limited to this configuration.

[0067] Furthermore, while the above example illustrates a configuration in which the calculation unit 111 adds or subtracts a predetermined value to the standard lead time of a corresponding process according to a single design condition, it is not limited to this. That is, the calculation unit 111 may be configured to add or subtract a predetermined value when, for example, multiple design conditions or construction conditions satisfy a predetermined condition. Alternatively, if multiple design conditions or construction conditions are set as settings related to the lead time in a single process, and multiple design conditions or construction conditions are satisfied, the calculation unit 111 may be configured to add or subtract only the predetermined value with the largest absolute value. In addition, the calculation unit 111 only needs to add or subtract a predetermined value to the standard lead time as a result, and may multiply by a predetermined coefficient during the process.

[0068] Furthermore, in steps S1 to S3, the acquisition unit 113 acquires the average value of lead times based on each actual lead time 251a stored in the actual lead time database 123, and the adoption rate of each design condition and construction condition based on each data stored in the actual condition database 124, but this is not limited to this. For example, due to legal revisions or changes in trends, the adoption trends of design conditions and construction conditions may differ significantly between the past and the present. In such cases, if the acquisition unit 113 acquires the average value and adoption rate that include data from past projects, there is a risk that the comparison results in step S6 will be incorrect. For this reason, for example, the actual lead time database 123 and the actual condition database 124 may be made to store the average value and adoption rate based on a portion of the data for a predetermined period, and the acquisition unit 113 may be made to acquire this data.

[0069] Furthermore, in step S1, an example was given in which the acquisition unit 113 acquires the average value of multiple actual lead times 251a stored in the actual lead time database 123 as the actual lead time value. However, the system is not limited to this, and it is also possible to acquire the actual lead time value by, for example, extracting a single actual lead time 251a.

[0070] Furthermore, Figure 4 illustrates a case where the actual lead times 251a of different locations are stored in the actual lead time database 123, and the acquisition unit 113 acquires the actual value of the adoption rate for a predetermined location in step S3. However, if, for example, a server device 10 is provided for each location, only the actual lead time 251a of one location may be stored in the actual lead time database 123. In this configuration, the actual value of the adoption rate acquired in step S2 becomes the actual value of the adoption rate at that location, so step S3 can be omitted.

[0071] Furthermore, while Figure 7 illustrates a configuration in which the lead time comparison screen 251 simply displays the actual lead time and the appropriate lead time 251b side by side, the system is not limited to this. For example, the display control unit 114 may highlight those actual lead times that exceed the appropriate lead time 251b. Examples of highlighting include changing the background color, changing the font size, font or color, or assigning a predetermined code. Also, while Figure 7 illustrates a case where lead times are compared and displayed for each process, the system is not limited to this. It may also display a breakdown of the tasks that make up each process to enable more detailed analysis.

[0072] Furthermore, while the above example illustrates a configuration for using the present invention in calculating lead time, it is not limited to this. That is, the present invention can be appropriately applied to calculating man-hours, the number of people required for a task, and so on. [Explanation of symbols]
