Description

BACKGROUND OF THE INVENTIONField of the InventionThe present invention relates to a value management server, a value management method, and a program that manages the values of goods so that devices and / or components owned by each company are set as goods that can be used by other companies.Prior ArtConventionally, for example, in a factory or the like that employs an industrial machine such as a machine tool or an industrial robot, when a device or a component that is a part of the device (hereinafter, the device and / or the component is also referred to as the part) constituting the industrial machine is defective, for example, the part is ordered. For example, Patent Document 1 discloses a component ordering system for ordering a component of an in-factory device from a component supplier outside the factory online. Patent Document 2 discloses an automatic component ordering method of an injection molding machine for ordering consumables and a consumable component of the molding machine in a time-dependent and reliable manner.For a part of parts having a relatively high possibility that the part will not be able to be used, a consumable and the like, spare articles (hereinafter, the spare articles are also referred to as spare parts) are stored in a factory or the like beforehand, and when they cannot be used, the spare parts stored are used.Patent Document 3 describes a method for distributing usage of at least one hand-held power tool and / or of at least one piece of equipment, wherein at least one time parameter of the at least one hand-held power tool and / or of the at least one piece of equipment and at least one location parameter of the at least one hand-held power tool and / or of the at least one piece of equipment are machine-processed in such a way that the at least one location parameter is used for locating and the at least one time parameter is used for indicating a temporal availability of the at least one hand-held power tool and / or of the at least one piece of equipment.Patent Document 1: JP 2003-173 379 APatent Document 2: JP 2005-258 585 APatent Document 3: DE 10 2017 205 344 A1SUMMARY OF THE INVENTIONGenerally, a part is not ordered until the part cannot be used. Therefore, it takes time to deliver the part, and thus a device cannot be operated in the meantime. If the spare part has been previously possessed, even if the part cannot be used, the spare part is used, and thus it is possible to operate the apparatus quickly. However, since a storage location is required for the spare part, it is nonrealistic to have spare articles for all parts. When spare parts for some parts are owned, it is problematic to determine which parts to own spare parts. Further, when a part whose spare part is not owned cannot be used, the part is ordered and waiting is made until the part is delivered.An object of the present invention is to provide a value management server, a value management method, and a program in which parts (devices and / or components) possessed as goods from a company serving as an economical entity are registered as goods that can be used by other companies in which the values of the goods are managed, and thus within a range of the sum total of the values of all of the goods registered by the company, the goods registered by the other companies can be used.This object is achieved by the subject matters of the independent claims.According to the present invention, it is possible to register a value management server, a value management method, and a program in which parts, devices, and / or components owned as goods by a company serving as an economical entity are registered as goods that can be used by other companies in which the values of the goods are managed, and thus within a range of the sum total of the values of all of the goods registered in the companies, the goods registered in the other companies can be used.BRIEF DESCRIPTION OF THE DRAWINGSFIG. 1 is an overall system configuration view of a spare part sharing system in the present embodiment and a block diagram of a server; FIG. 2 is a diagram showing an example of the storage unit of the server in the present embodiment; FIG. 3 is a diagram for illustrating a method of calculating the total values of spare parts in the present embodiment; FIG. 4 is a diagram for illustrating a basic concept of value management and the execution of spare parts in the spare part sharing system in the present embodiment; FIG. 5 is a flowchart showing the main processing of the server in the present embodiment; FIG. 6 is a diagram showing a display example in a terminal in the present embodiment; FIG. 7 is a flowchart showing the spare part registration processing of the server in the present embodiment; FIG. 8 is a diagram showing a display example in the terminal in the present embodiment; FIG. 9 is a diagram showing a display example in the terminal in the present embodiment; FIG. 10 is a diagram showing a display example in the terminal in the present embodiment; FIG. 11 is a flowchart showing the branch processing of the server in the present embodiment; and FIG. 12 is a diagram for illustrating the storage unit update processing in the server in the present embodiment.DETAILED DESCRIPTION OF THE INVENTIONEmbodimentAn outline of an embodiment of the present invention will be described first. The present embodiment relates to a system for managing the values of goods so that parts (devices and / or components) serving as (owned by) goods owned by a plurality of companies (economic entities) and relating to an industrial machine including a machine tool or an industrial robot are set as goods that can be used by other companies. More specifically, the present embodiment relates to a system (hereinafter referred to as a "spare parts sharing system") that manages spare parts (goods) owned (owned) by a plurality of companies (economic entities) and that mediates, in the rental of the spare parts between the companies based on values of the managed spare parts.The configuration of a spare part sharing system 100 in the present embodiment will be described. FIG. 1 is an overall configuration view of the spare part sharing system 100 in the present embodiment and a block diagram of a server 1. the spare part sharing system 100 includes the server 1 (serving as a value management server) and terminals 4 ( 4A, 4B, 4C,... ). The server 1 is operated and managed by a predetermined operation company. The terminals 4 (4A, 4B, 4C,... ) are terminals owned by individual companies. The companies having the terminals are companies using industrial machines such as a machine tool or an industrial robot. The terminal 4A is a terminal of a company A, and the terminals 4B and 4C are terminals of a company B and a company C, respectively. Although in the spare part sharing system 100 of this company, one or more terminals may be used, only one terminal is shown in FIG. 1. In the following discussion, when the terminals 4A, 4B, 4C,... are not distinguished, description will be simply described as the terminals 4.The server 1 and the terminals 4 are connected to each other via a network N so as to be able to communicate with each other. The network N is, for example, the Internet, a VPN (Virtual Private Network), or a public telephone network. There is no limitation to a specific communication method in the network N used for a wired connection or a wireless connection, and the like.[Server 1]The server 1 will then be described. FIG. 2 is a diagram showing an example of a storage unit 20 of the server 1 in the present embodiment. FIG. 3 is a diagram for illustrating a method of calculating the total values of spare parts in the present embodiment. The server 1 collects and manages information on spare parts possessed by the individual companies so as to mediate between the companies when the spare parts are being taught. The replacement parts refer to devices and / or components owned by each company that serve as replacement articles. The devices and / or components are, for example, a pulse encoder, a motor 5 kw, a wrist unit, a circuit board, and an IC chip, and are used in industrial machines such as a machine tool and an industrial robot. The server 1 shown in FIG. 1 includes a control unit 10, the storage unit 20, and a communication unit 30. the control unit 10 may be a CPU (Central Processing Unit) and executes various types of programs stored in the storage unit 20 and that control the server 1 to collectively control the server 1.The storage unit 20 will be described first, before the control unit 10. the storage unit 20 is a storage device such as a hard disk or a semiconductor storage element that stores programs, data, and the like necessary for the operation of the server 1. The storage unit 20 includes a program storage unit 21, a parts data storage unit 22, an enterprise data storage unit 23, a parts price storage unit 24, and a rental parts management unit 25. The machining program storage unit 21 stores programs 21 pfor executing the individual functional units of the control unit 10.The parts data storage unit 22 is a storage region in which information on the spare parts owned by the companies is stored. As shown in FIG. 2, the part data storage unit 22 stores a registration number, a business code (serving as identification information of the business entity), an address code, and a part code serving as the identification information of the commodity), a quantity, and a Darlhens flag so as to associate them with each other. The registration numbers are numbers indicating the order in which parts are registered in the part data storage unit 22, and are serial numbers provided in the order of registration from 1, for example. The company code is identification information for identifying the company, and differs from company to company. The address code is identification information for identifying the address of a factory or the like that the spare part actually has. The part code is identification information for identifying the spare part. The spare part can be identified by the address code and the part code. The size is the number of spare parts input when the spare part is registered. The Details flag indicates whether or not the spare part is lent, and is set to "0" at the time of registration. Then, when the spare part is lent, the lent flag is set to "1". Except when all the registered set of spare parts are lent simultaneously, it is likely that a part of the registered set of spare parts are lent and that their remaining set are not lent. In such a case, as will be described later, when the spare part is lent, for example, a branch number of the registration number is provided for the registration number of the spare part, thereby preferentially dividing a record of the size of spare parts lentent.The business data storage unit 23 is a storage region in which the information of the individual companies is stored. The information of the individual companies stored in the company data storage unit 23 is registered in advance when the individual companies start to employ the spare part sharing system 100. As shown in FIG. 2, the company data storage unit 23 stores the company code, the company name, and n (n is a natural number) addresses so as to associate them with each other. In addition, the business data storage unit 23 may store contact information (telephone number, e-mail address) and the like. The addresses are, for example, the locations of the company's main quarry, individual offices having spare parts, factories, and the like. The parts price storage unit 24 is a storage region in which prices of spare parts are stored. The parts price storage unit 24 is registered in advance. As shown in FIG. 2, the parts price storage unit 24 stores the parts code and the price so as to be associated with each other. The prices are, for example, market prices. The prices stored in the parts price storage unit 24 are also referred to as basic prices in the following description.The part-of-reading management unit 25 is a storage region in which information on the reading of the data part stored in the part data storage unit 22 is stored. As shown in FIG. 2, the rental part management unit 25 stores a date and time, a registration number, a rental company code, and a quantity so as to be associated with each other. Date and time is date and time that are input when the replacement part is given as a rental. The registration number corresponds to the registration number of the parts data storage unit 22. The amount is the number of spare parts that are lent.The storage unit 20 also stores a spare part table (an address table and the like). The spare part table is a table in which the names of the spare parts and the part codes are associated with each other. In the spare parts table, various types and specifications (such as specifications, failure occurrence rates, and management cost) of the spare parts can be stored. The address table is a table in which the addresses and the address codes are associated with each other. The individual storage units described above are examples.The individual functional units included in the control unit 10 shown in FIG. 1 will then be described. The control unit 10 includes a part registration unit 11, a ratio calculation unit 12, a value calculation unit 13, a first output unit 14, a second output unit 15, a notification unit 16, and a rental processing unit 17 (serving as an IOU reception unit and an IOU assignment unit). The parts registration unit 11 receives spare part information input from the terminal 4, uses the tables such as the spare part table and the address table described above, and the business data storage unit 23 so as to convert the spare part information into codes, and stores it in the parts data storage unit 22.The ratio calculation unit 12 calculates a ratio corresponding to the total amount of the same spare part as a spare part registered in the part registration unit 11 in all the spare parts stored in the part data storage unit 22, and stores it in the storage unit 20. As the ratio corresponding to the total amount of the same spare part as the spare part registered by the part registration unit 11, for example, a value obtained by multiplying the total amount of the spare part by 0.01 may be adopted. As described later, this ratio is subtracted from the value of the spare part, and thus it is possible to provide a configuration in which, as the total amount of the spare part is increased, the total value is decreased.The value calculation unit 13 calculates the value of each spare part registered by the part registration unit 11. Specifically, for example, as the value calculation unit 13, a value calculation unit that multiplies the market price of the spare part by a failure occurrence rate can be used. In this way, the value of a spare part having a high failure occurrence rate can be calculated to be high for the reason that the frequency of use of the spare part is high. In contrast, the value of a spare part having a low failure occurrence rate can be calculated to be low for the reason that the frequency of use of the spare part is low. Therefore, the value more appropriate for the real situation can be calculated.As another example of the value calculation unit 13, a value calculation unit in which management costs for storing the spare part are taken into account at the market price may be employed. For example, the management costs do not differ between a spare part that needs to be stored in a clean room and a spare part that is stored in a warehouse. Since additional management costs are required for the spare part to be stored in a clean room, the value of the spare part can be calculated to be high. The value calculation unit 13 is not limited to these examples. The market price of an asset can be set as the value of the asset without being changed. Based on the specifications and the like of a spare part, a calculation method can be arbitrarily set.As described above, in the value calculation unit 13, the "total value" that is a relative value can be calculated in consideration of the total amount of the same spare part as the spare part registered in the part registration unit 11. The value at which the total amount of the same spare part is taken into account is specifically referred to as a "total value". In contrast, the above-described value determined by the specifications and the like of the spare part itself is referred to as a "base value". In the following description, when the "base value" and the "total value" are not distinguished, they are simply referred to as the "value".Specifically, as the value calculation unit 13 that calculates the "total value", the following example may be mentioned. In the value calculation unit 13, for example, assuming that the base value is A and that the total amount of the spare part is B, the following formula is used as a predetermined formula, and thus the total value X, which is the value of a registered spare part, can be calculated.Here, "B×0.01" is the ratio calculated by the ratio calculation unit 12 and stored in the storage unit 20. (Formula 1) is an example, and the formula for calculating the total value X, which is the value of a registered replacement part, is not limited to this formula. The formula can be set as necessary according to specifications and the like of an article.FIG. 3 shows examples of the total value X calculated by the above-described (formula 1) for the individual substitutes.For example, in a "pulse encoder" which is one of the spare parts, the base value A is 10 and the total amount B is 200. Then, the value calculation unit 13 calculates the total value X of the "pulse encoder" by applying to (Formula 1) so that the total value X is 8.0. In a "wrist unit" which is one of the substitutes, the base value A is 100 and the total amount B is 2. then the value calculation unit 13 calculates the total value X of the "wrist unit" by applying to (Formula 1) so that the total value X is 100.0. As described above, as the total amount B increases, the total value X decreases with respect to the base value A. This is because the total value X of a rare spare part is set unchanged with respect to the base value A, while the total value X of a spare part registered in a large amount is set lower than the base value A. The value calculation unit 13 described above that calculates the "total value" is not limited to this example. As long as the total value of the rare substitute increases, another calculation method may be employed.The first output unit 14 outputs the value calculated by the value calculation unit 13 to the terminal device 4 which inputs the spare part information. The first output unit 14 may output the value of the spare part registered by the part registration unit 11. The first output unit 14 may also output a usable value obtained by summing up the values of individual spare parts including already registered spare parts registered by the company as a usable value possessed by the company. The second output unit 15 outputs information on the spare parts stored in the parts data storage unit 22 to all the terminals 4. The information output by the second output unit 15 is information registered in the spare part sharing system 100 and related to the spare parts that can be lended by individual companies.When the notification unit 16 receives a use request from a company (hereinafter, also referred to as a darhensee company) who desires to use a spare part, that is, which desires to receive the darhens of a spare part, the notification unit 16 provides notification to the terminal 4 of a company (hereinafter, also referred to as a "darhensee company") who owns the spare part and which gives it. Here, the notification unit 16 receives the use request within the range of a usable value owned by the phonograph company. When the rental of the spare part is established, the borrow processing unit 17 between the terminal 4 performs processing such as support for creating an IOU and delivery thereof. The communication unit 30 is a communication control device that transmits and receives data to and from the terminal 4.[Terminal 4]The terminal 4 is, for example, a personal computer (PC) owned by each company. The terminal 4 may be a portable terminal such as a tablet terminal or a smartphone. The terminal 4 includes a control unit, a storage unit, an input unit, a display unit, a communication unit, and the like (all of which are not shown). Each company uses the terminal 4 to communicate with the server 1, thereby performing various kinds of processing such as registration of spare parts, request for spare parts, and conferment of spare parts, which will be described later.The devices included in the spare part sharing system 100 described above may be individually realized by hardware, software, or a combination thereof. Here, the realization by software means that a computer reads and executes programs (applications) so as to achieve the realization. As a specific example, the server 1 may be realized by incorporating programs (application) for realizing the present embodiment into a common server.[Schematic Description]A basic path of thinking about value management and the rental of spare parts in the spare part sharing system 100 will then be described. FIG. 4 is a diagram for illustrating a basic concept of value management and spare parts learning in the spare part sharing system 100 of the present embodiment. It is assumed that the company A, the company B, and the company C shown in FIG. 4 all have registered own spare parts in the server 1. The control unit 10 of the server 1 calculates the values of individual spare parts registered, and sets certain values to a usable value for the company by multiplying the values by the amounts of the spare parts registered by each company. Fig. 4 shows the usable values of the spare parts registered by the individual companies.In a divided region 31, value regions 32, 33, and 34 of the individual companies are shown. The values of all spare parts registered by the company A are shown as a usable value in the value region 32. The values of all spare parts registered by the company B are shown as a usable value in the value region 33, and the values of all spare parts registered by the company C are shown as a usable value in the value region 34. Here, the calculated values do not identify the spare parts. By the sizes of the value regions 32, 33, and 34, the sizes of the usable values are found. Each company may receive the rental of spare parts possessed by the other companies within the range of the usable value of the spare parts registered by the company. For example, since the usable value of the company A is larger than the usable value of all spare parts registered by the company B, if the company A receives the rental of all the spare parts registered by the company B, the company A may receive the rental of all spare parts. However, on the other hand, if the company B receives the rental of all the spare parts registered by the company A, the company B may receive the rental of spare parts only within the range of the usable value of the spare parts registered by the company B from the spare parts registered by the company A.The usable values of the individual companies indicated by the value regions 32, 33, and 34 are not proportional to the number of registered spare parts. As described above, when the base price of the registered spare part is increased, the value tends to be increased. Further, a configuration may be employed in which as the failure occurrence rate of the part increases, the frequency of use thereof increases, and thus the value thereof increases. Further, a configuration may be adopted in which as the management cost of the part increases, the value thereof increases. As the value, the "total value" is applied, and thus, when the registered spare parts are not registered by other companies, the spare parts are rare, whereby the value thereof can be increased. The values are increased, and thus the usable value obtained by summing these values is increased.[Description of Processing]The processing in the server 1 will then be described. FIG. 5 is a flowchart showing the main processing of the server 1 in the present embodiment. FIGS. 6 and 8 to 10 are diagrams showing display examples in the terminal 4 in the present embodiment. FIG. 7 is a flowchart showing the spare part registration processing of the server 1 in the present embodiment. FIG. 11 is a flowchart showing the branch processing of the server 1 in the present embodiment. FIG. 12 is a diagram for illustrating storage unit update processing in the server 1 in the present embodiment.The server 1 and the terminal 4 are first connected to each other so as to communicate with each other, for example, in the terminal 4, the user of the terminal 4 inputs log-in information from the initial screen, which is not shown, so as to start the log-in, and thus, in S 10 of FIG. 5, the control unit 10 of the server 1 receives a log-in request.In S 11, the control unit 10 performs authorization, and when the authorization is achieved, the control unit 10 (the first output unit 14) outputs, for example, a menu screen 50 shown in FIG. 6 to the terminal 4. The menu screen 50 includes a log-in display region 50 a, a value display region 50 b, and buttons 50 cto 50 e. The log-in display region 50 aindicates that the company A logs in. The value display region 50 bdisplays, as the usable value, the values of all spare parts registered by the company A. The keys 50c to 50e are keys which receive a selection operation so as to perform the subsequent processing. The key 50c is used when a replacement part is registered. The key 50d is used when it is desired that the execution of a spare part is received. The key 50e is used when log-out is performed.In S 12 of FIG. 5, the control unit 10 determines whether or not to register a spare part. When the button 50 cis selected on the menu screen 50 described above, the control unit 10 determines that the replacement part is registered. When the spare part is registered (S 12: YES), the control unit 10 sends the processing to S 13. On the other hand, when the spare part is not registered (S 12: NO), the control unit 10 transfers the processing to S 14. In S 13, the control unit 10 (the parts registration unit 11) performs spare part registration processing.Here, the spare part registration process will be described with reference to FIG. 7. In S 30 of FIG. 7, for example, the control unit 10 outputs a spare part registration screen 51 shown in FIG. 8 to the terminal 4. The spare part registration screen 51 includes a log-in display region 51 a, a detail input region 51 b, a connection unit 51 c, and buttons 51 dand 51 e. The log-in display region 51 aindicates that the company A logs in. The detail input region 51 bis a region in which the name, the amount, and the storage location of the spare part are input. The detail input region 51 bmay be configured such that the spare part and the storage location can be easily input by selecting from a pull-down list, for example. The connection unit 51 cis used when a plurality of details need to be input. When the connection unit 51 cis selected, a record is added in the detail input region 51 bin a downstream direction, and thus the input of another spare part can be performed. The keys 51d and 51e are keys that receive a selection operation so as to perform the subsequent processing. The key 51d is used when the replacement part is registered. The key 51e is used when the spare part is not registered.In S 31 of FIG. 7, the control unit 10 determines whether or not to add the record. For example, when the selection of the connection unit 51 cis received on the spare part registration screen 51 shown in FIG. 8, the control unit 10 determines that the record is added. When the record is added (S 31: Yes), the control unit 10 transmits the processing to S 32. On the other hand, when the record is not added (S 31: NO), the control unit 10 transfers the processing to S 33. In S 32, the control unit 10 performs record addition processing for adding the record to the detail input region 51 b. A configuration may be adopted in which addition of a plurality of data sets can be performed. In S 38, the control unit 10 determines whether or not to record the spare part input in the detail input region 51 b. For example, when the selection of the key 51 dshown in FIG. 8 is received, the control unit 10 determines that the spare part is recorded. When the spare part is recorded (S 33: Yes), the control unit 10 transfers the processing to S 34. On the other hand, when the spare part is not recorded (S 33: NO), the control unit 10 concludes the present processing and transfers the processing to S 18 in FIG. 5.In S 34, the control unit 10 (the parts registration unit 11) performs registration processing. Specifically, the control unit 10 registers the information on the spare part input to the detail input region 51 bshown in FIG. 8 in the part data storage unit 22, Here, the control unit 10 acquires a part code corresponding to the name and an address code corresponding to the input storage space from the tables not shown, and registers them. In S 35, the control unit 10 (the value calculation unit 13) calculates the value of the registered spare part. When the "total value" is applied as the value as described above, for example, the control unit 10 adds the total amount of individual spare parts registered in the original total amount and then applies the result (Formula 1) so as to calculate the total value.In S 36, for example, the control unit 10 (the first output unit 14) outputs a registration screen 52 shown in FIG. 9 to the terminal 4. The registration screen 52 includes a log-in display region 52 a, a value display region 52 b, and a button 52 c. The log-in display region 52 aindicates that the company A logs in. The value display region 52 bdisplays, as the forward movements value, the values of all spare parts registered by the company A. As compared with the menu screen 50 of FIG. 6, the value of the spare parts displayed in the value display region 52 bis increased by the value resulting from the registration of the spare part. The key 52c receives a selection operation so as to perform the subsequent processing. The button 52c is used when the registration screen 52 is confirmed. Thereafter, the control unit 10 concludes the present processing and transfers the processing to S 18 of FIG. 5.A description will be given with reference back to FIG. 5. In S 14 of FIG. 5, the control unit 10 determines whether or not to make a request about the spare part. When receiving the selection of the button 50 din the menu screen 50 shown in FIG. 6, the control unit 10 determines that the request about the spare part is made. When the request about the spare part is made (S 14: Yes), the control unit 10 transfers the processing to S 15. On the other hand, when the request about the spare part is not made (S 14: NO), the control unit 10 transfers the processing to S 18.In S 15, the control unit 10 (the first output unit 14, the second output unit 15) outputs, for example, a divided part screen 53 shown in FIG. 10 to the terminal 4. The divided part screen 53 includes a log-in display region 53 a, a value display region 53 b, a value display region 53 c, and buttons 53 dand 53 e. The log-in display region 53 aindicates that the company A logs in. The detail list region 53 bdisplays, as a list, all spare parts registered as shared spare parts (shared goods) by the individual companies on an individual basis for the names and the storage locations. In this example, as the storage locations, only city, district, town and town are displayed, and thus, places cannot be identified. In the detail list region 53 b, the number of spare parts desired to be used can be input. The value display region 53 cdisplays the value that can be used by the company (in this case, the company A) logging in. The keys 53d and 53e are keys that receive a selection operation so as to perform the subsequent processing.The user of the terminal 4 checks whether or not the spare part desired to be lent is present from the list of the detail list region 53b, and when the spare part desired to be lent is present, the user checks the amount and the storage space. Here, the user preferably searches for a spare part in a storage place close to the facility that wants to receive the rental of the spare part. The replacement part is delivered from the storage location to a destination specified by the Darhense company. Therefore, in order to reduce cost and time for delivery, it is preferable to look for a storage location close to the destination specified by the possessor company. Then, when the record of the spare part desired to be lent is found, the user of the terminal 4 inputs the amount of the spare part to be lent into the record in the number of spare parts desired to be used, and selects the key 53d. Here, the user of the terminal 4 checks, with reference to the usable value displayed in the value display region 53 c, whether or not the value of the substitute part desired to be used falls within the range of the usable value, and inputs the use request. A configuration may be employed in which the control unit 10 determines whether or not the value is usable based on the value of the spare part where the number of spare parts desired to be used is input and the usable value, and only when the value is usable, the button 53 dis released.In S 16 of FIG. 5, the control unit 10 determines whether or not to receive the rental of the spare part, that is, whether or not the spare part is desired to be used. When the selection of the button 53 dshown in FIG. 10 is received, the control unit 10 determines that the rental of the spare part is received. When the rental of the spare part is received (S 16: Yes), the control unit 10 transfers the processing to S 17.On the other hand, when the rental of the spare part is not received (S 16: NO), the control unit 10 transfers the processing to S 18. The case where the use is not desired refers to, for example, a case where the selection of the button 53 eshown in FIG. 10 is received. In S 17, the control unit 10 performs a thiehen processing.Here, the thirhens processing will be described with reference to FIG. 11. In S 40 of FIG. 11, the control unit 10 performs the storage unit update processing. Specifically, the control unit 10 updates the performance flag of the record which is the performance target from "0" to "1" of records stored in the part data storage unit 22. If the amount in the record is plural and is larger than the amount to be leased, if the rental flag of the record which is the rental destination is updated from "0" to "1", all spare parts are leased, and it is not preferable to do so. Therefore, as shown in FIG. 12, one record 60 is divided into two records 60a and 60b. Then, a branch number is provided to the newly generated record 60b, and the amount to be leased is subtracted from the registered amount in the original record 60a. As shown in FIG. 12, the control unit 10 adds a record 61 to the thirtieth part management unit 25 and inputs predetermined values into individual items.In S 41 of FIG. 11, the control unit 10 (the notification unit 16) notifies the possessor company of information that the possessor is received. The control unit 10 may provide the notification such as by e-mail, and may display as a notification item on the menu screen of the spare part sharing system 100 or the like. In S 42, the control unit 10 (the borrow processing unit 17) transmits, for example, a template of an IOU to the rental company. In the template of the IOU, articles for identifying companies such as the names of the Darhensor company and the Darhenser company are not described. This is because the names of companies and the like are hidden for both companies so as to ensure secretization. The Phonograph company uses the template of the IOU that it has received so as to create an IOU and sends it to the server 1.In S 43, the control unit 10 determines whether or not the IOU is received from the rental company. When the IOU is received (S 43: Yes), the control unit 10 transfers the processing to S 44. On the other hand, when the IOU is not received (S 43: No), the control unit 10 remains in the present processing until the reception of the IOU. In S 44, the control unit 10 (the borrow processing unit 17) generates the IOU so as to give it to the phonograph company. Thereafter, the control unit 10 transfers the processing to S 18 of FIG. 5.In S 18 of FIG. 5, the control unit 10 receives an operation of logging out so as to determine whether or not log-out is to be performed. When the log-out is performed (S 18: Yes), the control unit 10 completes the current processing. On the other hand, when the log-out is not performed (S 18: NO), the control unit 10 transfers the processing to S 11.The rental company receiving the rental is obligated to purchase the same part as the rental spare part to return it. In this manner, the rental flag of the parts data storage unit 22 is changed to "0", and thus the rental state is canceled as by clearing the corresponding entry from the rental parts management unit 25.As described above, in the spare part sharing system 100, the server 1 manages the spare parts of the individual companies and mediates in the branch processing. Therefore, each enterprise employs the replacement part sharing system 100 to be able to receive from other enterprises the rental of the replacement parts that are not owned by the enterprise. Thus, the enterprise may receive and wait for the spare parts earlier than the enterprise orders. The above-described mechanism is established, and thus it is possible to provide an opportunity to register the spare parts owned by each company in the server 1. The rental can be performed within the range of the usable value of the spare parts registered by each company, and thus it is possible for each company to be provided with an opportunity to have a certain number of spare parts.When the "total value" is applied as the value of the spare part, it corresponds to the total amount of the same spare part as the registered spare part of all spare parts registered spare parts. Therefore, the total value of the spare part in which a small number of spare parts are registered can be increased.Further, since concealing for brake control of the IOU is secured, the rental of a spare part can be performed without noticing internal information related to processing of a product in each company.The programs used in the present invention are stored with various kinds of non-transitory computer readable media and can be supplied to a computer. The non-transitory computer readable media include various types of tangible storage media. Examples of the non-transitory computer readable media include magnetic recording media (for example, a flexible disk, a magnetic tape, and a hard disk drive), magneto-optical recording media (for example, a magneto-optical disk), CDROM (Read Only Memory), CD-R, a CD-R / W, and semiconductor memories (for example, a mask ROM), and a PROM (Programmable ROM), an EPROM (Erasable PROM), a flash ROM, and a RAM (Random Access Memory)). The programs may also be provided to a computer having various types of transitory computer readable media. Examples of the transitory computer readable media include an electrical signal, an optical signal, and electromagnetic waves. The transitory computer readable media may supply the programs to a computer via a wired communication path such as an electric wire, or an optical fiber, or a wireless communication path.Although the above-described embodiment is a preferred embodiment of the present invention, the scope of the present invention is not limited to only the above-described embodiment, and various modifications are made without departing from the spirit of the present invention, so that the present invention can be practiced.(Variation 1)Although in the above-discussed embodiment, the description is given of the example in which the user who wants to receive the rental of a spare part desires to use the spare part stored in a storage place close to a place in which the spare part is needed by the company of the user, there is no limitation to this configuration. For example, a configuration may be employed in which the place where the spare part is required by the user's company is input by selection, and thus a spare part stored in a storage place is selected close thereto by the server, or is output to a position where the spare part is easily seen.(Variation 2)Although in the description of the embodiment discussed above, the enterprise serving as the business entity employing the spare part sharing system 100 is an enterprise using an industrial machine, there is no limitation to this description. For example, specialists such as a system integrator and an MTB may be included.EXPLANATION OF REFERENCE NUMERALS1 Server 4 Terminal 10 Control unit 11 Parts registration unit 12 Ratio calculation unit 13 Value calculation unit 14 First output unit 15 Second output unit 16 Notification unit 17 Borrow processing unit 20 Storage unit 20 pProgram 22 Parts data storage unit 23 Business data storage unit 24 Parts price storage unit 25 Thiehens parts management unit 100 Spare parts sharing system
