Description

[Technical field]

[0001] The present invention relates to a maintenance support system, a maintenance support method, and a program. [Background technology]

[0002] In recent years, an increasing number of companies are working on carbon neutrality and circular economy, and it is becoming increasingly important to create environmental value, not just costs. In order to improve environmental value, it is also important to promote the reuse of products, to use recycled parts made from parts recovered from discarded products, or to use recycled materials made by returning discarded products to their original materials and reusing them.

[0003] The home appliance and automobile industries have a large volume of products distributed in the market, have established laws and regulations regarding recycling, and are leading the way in environmental response. On the other hand, in areas such as production equipment where the volume of products distributed is small, there are many cases where redesign technology for recycled parts and systems for reproduction are not in place, and there are issues with contributing to the circular economy.

[0004] Patent Document 1 discloses a device for managing support information required for reuse of products. Specifically, Patent Document 1 describes that "In the product information management server SV, attribute information, usage history information, maintenance history information, and CO2 emission information of battery modules manufactured by multiple storage battery manufacturers are collected, correlated with each other, and stored in a DB. Then, when an information viewing request is received, reuse support information is generated based on the attribute information, usage history information, maintenance history information, and CO2 emission information of the corresponding battery module, and the generated reuse support information is transmitted to the requester."

[0005] [Patent Document 1] JP 2021-189568 A Summary of the Invention [Problem to be solved by the invention]

[0006] In order to achieve carbon neutrality and a circular economy, it is important to make efforts to extend the lifespan of products, and this can be done by carrying out maintenance such as appropriate part replacement, etc. Also, if products that have reached the end of their lifespan can be disassembled and the reusable parts and assemblies can be reused in other products, the amount of new products manufactured can be reduced, which contributes to carbon neutrality and a circular economy.

[0007] The technology of Patent Document 1 discloses providing reuse support information for reusing battery modules. However, the technology of this document does not take into consideration supporting the reconditioning and remanufacturing of products and parts (refurbishment). Therefore, the technology of this document has room for improvement in addressing the above-mentioned problems.

[0008] The present invention has been made in consideration of the above problems, and aims to promote the extension of product life and reduction of production volume by presenting information useful for deciding whether to perform maintenance such as repairs, thereby contributing to a circular economy, etc. [Means for solving the problem]

[0009] The present application includes a number of means for solving at least part of the above problems, examples of which are as follows: A maintenance support system according to one aspect of the present invention for solving the above problems is a maintenance support system having one or more processors and one or more memory resources, wherein the memory resources store a maintenance support program, and by executing the maintenance support program, the processor determines a repair amount corresponding to a degree of deterioration and a repair cost corresponding to a repair process for a part or assembly to be maintained, generates maintenance support information including the repair amount, the repair cost, and the repair process, and outputs the maintenance support information to a specified device. Effect of the Invention

[0020] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0021] The maintenance support system 100 according to this embodiment performs processing to support the maintenance of parts and assemblies (hereinafter referred to as "parts, etc.") mounted on a product (e.g., equipment). Specifically, the maintenance support system 100 calculates the repair amount of parts, etc. that have deteriorated (e.g., worn out) with the use of the product, the repair cost according to the repair process, etc., and presents it to the user as information to support maintenance.

[0022] By presenting the user with information that is useful for determining whether or not to perform such repair and maintenance, the maintenance support system 100 can promote the extension of product lifespans and the reduction of production volumes, thereby contributing to a circular economy, etc.

[0023] <Overview of the maintenance support system 100> 1 is a diagram showing an example of a schematic configuration of a maintenance support system 100 according to this embodiment. The maintenance support system 100 acquires various information used in processing from an external device 10, and stores the information in a corresponding database in a memory resource 30. The maintenance support system 100 also executes a maintenance support process, and obtains the repair amount and the cost of the repair process for the parts to be maintained. The maintenance support system 100 also outputs (transmits) the obtained information to a predetermined computer (for example, including the maintenance support system 100 used by a user or the external device 10).

[0024] The maintenance support system 100 and the external device 10 are connected to each other via a communication cable or a predetermined communication network N (for example, the Internet, a LAN (Local Area Network), or a WAN (Wide Area Network)).

[0025] <<External device 10>> The external device 10 is a computer that provides various types of information to the maintenance support system 100. Specifically, the external device 10 provides (transmits) to the maintenance support system 100 various types of latest information, such as regulatory information and maintenance record information on parts and products in which the parts and products are used.

[0026] Moreover, the external device 10 is a computer that displays information generated by the maintenance support system 100 (for example, information for supporting maintenance, such as the repair amount and cost of parts, etc.).

[0027] In addition, the external device 10 that provides information to the maintenance support system 100 and the external device 10 that displays the information generated by the maintenance support system 100 may be the same computer or may be different computers.

[0028] <Details of Maintenance Support System 100> The maintenance support system 100 is a processor system that executes various processes by the processor 20 reading the program 210 and various information stored in the memory resource 30. Specifically, the maintenance support system 100 executes a maintenance support process for generating maintenance support information. The details of this process will be described later.

[0033] The NI 40 is a communication device that performs information communication with the external device 10. The NI 40 performs information communication with the external device 10 via a communication network N. Note that, unless otherwise specified below, information communication between the maintenance support system 100 and the external device 10 is assumed to be performed via the NI 40.

[0034] The UI 50 is an input device that inputs operator instructions to the maintenance support system 100, and an output device that outputs information generated by the maintenance support system 100.

[0035] Furthermore, the output device may be, for example, a display, a printer, a voice synthesizer, etc. Unless otherwise specified below, it is assumed that the operator's operations on the maintenance support system 100 (for example, inputting and outputting information, and issuing instructions to execute processing, etc.) are performed via the UI 50.

[0036] Furthermore, the configurations, functions, processing means, etc. of the maintenance support system 100 may be partly or entirely realized in hardware, for example by designing them as integrated circuits. The maintenance support system 100 may also be partly or entirely realized in software, or may be realized by a combination of software and hardware. The maintenance support system 100 may use hardware having fixed circuits, or may use hardware having at least some of its circuits that are changeable.

[0037] Furthermore, the maintenance support system 100 can also be realized by an operator performing some or all of the functions and processes realized by each program.

[0038] The programs executed by the maintenance support system 100 may be stored in a non-volatile storage medium that can be read by the system. The programs stored in the non-volatile storage medium may be directly read by the maintenance support system 100, or a processor system for program distribution may read the programs from the medium and then transmit (distribute) the programs from the processor system for program distribution to the maintenance support system 100. Examples of non-volatile storage media include the non-volatile memory described as the memory resource 30, but other optical disk media may also be used.

[0039] <<Regulation Information DB (Database) 110>> The regulation information DB 110 is a database that stores regulation information, which includes information on materials used in parts and the like, and various regulations on parts and products.

[0040] 2 is a diagram showing an example of the regulation information. As shown in the figure, the regulation information includes various types of information on regulations, such as regulations on materials used, regulations on emissions of environmental pollutants, regulations on noise, regulations on energy consumption, and regulations on ensuring safety.

[0041] The regulatory information includes not only currently applied regulations, but also regulations that are set to be applied in the future. For example, materials that will become unusable in one year or other regulatory content are also registered.

[0042] <<Maintenance record information DB120>> The maintenance record information DB 120 is a database that stores maintenance record information, which includes records of maintenance performed on parts and the like.

[0043] 3 is a diagram showing an example of maintenance record information. As shown in the figure, the maintenance record information includes various types of information related to maintenance, such as a product code, an item code, a dimension record, a usage history record, a replacement part record, and a replacement frequency record.

[0044] The product code is information that uniquely identifies a product that contains a part, etc. The item code is information that uniquely identifies a part, etc. The dimension record is information that indicates the dimensions of the part, etc. that were recorded during maintenance. In other words, the dimension record records the dimensions of the part, etc. in a deteriorated state.

[0048] 4 is a diagram showing an example of sales information. As shown in the figure, the sales information includes various types of information related to sales, such as delivered devices, the number of devices delivered, control numbers, device prices, and maintenance prices.

[0049] The delivered equipment is information about equipment delivered to a business destination (e.g., product code, product type, etc.), and is registered with, for example, the delivery date. The number of units delivered and the management number are information indicating the number of units delivered and the management number of the delivered equipment, respectively. The equipment price and maintenance price are information indicating the selling price of the delivered equipment and the cost incurred during maintenance, respectively.

[0050] <<Product design information DB140>> The product design information DB 140 is a database that stores product design information, which includes information about the design of a product, including parts, etc.

[0051] Fig. 5 is a diagram showing an example of product design information. As shown in the figure, the product design information includes various information related to product design, such as product codes, item codes, drawings, part design dimensions, assembly design dimensions, design tolerance dimensions, product life, product performance, materials, and specified maintenance frequency.

[0052] The product code is information that uniquely identifies a product. The item code is information that uniquely identifies each part, etc., mounted on the product. The drawing is information that indicates a drawing of a product including parts, etc.

[0053] Moreover, the part design dimensions and the assembly design dimensions are information indicating the design dimensions of the parts, etc. The design tolerance dimensions are information indicating the design tolerance of the parts, etc., that is, the allowable range of variation in size.

[0054] Furthermore, product life and product performance are information indicating the product's life and specifications based on the specifications, respectively.

Product performance also includes information related to regulatory information, such as the product's emissions of environmental pollutants (e.g., CO2, etc.), noise levels, energy consumption, and safety assurance levels derived from the specifications. Materials are information indicating the materials used in parts, etc. Specified maintenance frequency is information indicating the recommended frequency of maintenance for the product and each part, etc.

[0055] For a product that has undergone a design change, such as a minor change, the product design information DB 140 stores information on both the old design before the design change and the new design after the design change.

[0056] <<Product manufacturing information DB150>> The product manufacturing information DB 150 is a database that stores product manufacturing information, which includes information about the manufacturing of products, including parts, etc.

As shown in the figure, the product manufacturing information includes various information related to product manufacturing, such as product code, item code, manufacturing process, manufacturing lead time, lead time by repair process, manufacturing cost, cost by repair process, and manufacturing quality variation.

[0058] The product code is information that uniquely identifies a product. The item code is information that uniquely identifies each part, etc., mounted on the product. The manufacturing process is information that indicates the manufacturing method of the product, and for example, the manufacturing process and the manufacturing process for each process are registered.

The cost by repair process is information indicating the cost for each repair process of parts, etc. The manufacturing quality variation is information indicating the manufacturing accuracy of products, parts, etc., and information indicating the range of variation in the shape and size of products, parts, etc. relative to design dimensions, for example, is registered.

[0060] Furthermore, for a product that has undergone a design change, such as a minor change, the product manufacturing information DB 150 stores both manufacturing information for the old design and manufacturing information for the new design.

[0061] The information stored in each of these databases is updated successively based on the latest information acquired via the external device 10.

[0062] <<Maintenance Support Program 211>> The maintenance support program 211 is a program that presents information useful for determining whether or not to perform maintenance. Specifically, the maintenance support program 211 executes a maintenance support process. More specifically, the maintenance support program 211 determines whether or not a part to be maintained complies with various regulations, and obtains useful information such as the amount of repair and the cost of repair in the case of repair, and presents the information to the user.

[0063] The maintenance support system 100 has been described above in detail.

[0064] <Maintenance support processing> 7 is a flow diagram showing an example of a maintenance support process executed by the maintenance support system 100. The maintenance support system 100 starts the process when, for example, an execution instruction is received from an operator. The maintenance support process is executed by the processor 20 that has read the maintenance support program 211.

[0065] When the process starts, the processor 20 accepts input of the product code of the product to be maintained and the item codes of the target parts, etc. (step S10). Specifically, the processor 20 accepts input of the item codes of the parts, etc. that are determined to need to be replaced during maintenance of the target product and the product code of the target product from the operator.

[0066] Next, the processor 20 determines whether the target product and the target parts can be used continuously (step S20). Specifically, the processor 20 identifies the materials used in the target parts and the product performance (specifications) related to the regulation information from the product design information. The processor 20 also compares the identified information with the regulation information, and determines whether the target product and the target parts can be used continuously depending on whether the target product and the target parts fall under various regulations registered in the regulation information.

[0067] The user of the maintenance support system 100 may determine whether or not continued use is possible and input the determination. Specifically, the processor 20 identifies, for example, the material used in the target part and the product performance related to the regulatory information from the product design information, and displays it on the display together with the maintenance information. The processor 20 also executes the determination process based on the input from the user who has determined whether or not continued use is possible.

[0068] If it is determined that continued use is possible (Yes in step S20), the processor 20 transitions the process to step S30. On the other hand, if it is determined that continued use is not possible (No in step S20), the processor 20 transitions the target product and target parts to a prescribed disposal process or recycling process (step S90). Note that, by executing the disposal process or recycling process, the target product, target parts, etc. are disposed of or recycled in a prescribed manner and reused.

[0069] In step S30, the processor 20 identifies the degree of deterioration of the target part, etc. Specifically, the processor 20 identifies the degree of deterioration of the target part, etc. (3 mm) based on the difference between the design value (e.g., thickness 8 mm) of the target part, etc. (e.g., gear) in the product design information and the dimensional record (e.g., thickness 5 mm) in the maintenance record information.

[0070] Next, the processor 20 identifies the tolerances of the target parts, etc., based on the latest product design information (step S40). Specifically, for products without design changes of the target parts, etc., the processor 20 identifies the tolerances of the target parts, etc. (e.g., ±0.2 mm) using the current product design information. For products with design changes of the target parts, etc., the processor 20 identifies the tolerances of the old design (e.g., ±0.2 mm) and the tolerances of the new design (e.g., ±0.1 mm) using the old and new product design information.

[0071] Next, the processor 20 executes an evaluation for reconditioning (step S50). Specifically, the processor 20 identifies a repair process for the target part, etc. (for example, a predetermined process for repairing the thickness of a gear), a cost required for the repair process, a lead time for the identified repair process, and a value of manufacturing quality variation of the target part, etc., from the product manufacturing information.

[0072] In addition, the processor 20 identifies the manufacturing process for manufacturing the target part etc. without repair, the cost involved in the manufacturing process, the manufacturing lead time, and the value of the manufacturing quality variation of the target part etc. from the product manufacturing information.

[0073] Next, the processor 20 executes the re-maintenance design (step S60). Specifically, the processor 20 calculates the repair amount of the target part, etc. (in this example, the repair amount is 3 mm when repairing the thickness of 5 mm in the deteriorated state to the design value of 8 mm) and the repair tolerance, which is the difference between the tolerance of the old design and the tolerance of the new design (in this example, ±0.1 mm), and sets these as the re-maintenance design.

[0074] Next, the processor 20 generates maintenance support information including these pieces of information (step S70) and outputs (displays) it on the display (step S80). Note that, when a user operates the maintenance support system 100 via the external device 10, the maintenance support system 100 may cause the external device 10 to display the maintenance support information.

[0075] After outputting the maintenance support information, the processor 20 ends the processing of this flow.

[0076] 8 is a diagram showing an example of a display screen of the maintenance support information. As shown in the figure, the maintenance support information includes a rework design in the case of repair and a manufacturing design in the case of remanufacturing without repair, and each design is displayed so as to be compared.

[0077] The contents of the maintenance support information are not limited to the items exemplified in FIG. 8, and it is also possible to display any combination of items desired by the user.

[0078] The maintenance support process has been described above.

[0079] In this way, by displaying the maintenance support information, the maintenance support system 100 can provide useful information that the user can use as a consideration when deciding whether or not to repair a part or the like.

[0080] In particular, the user can determine in advance whether or not reconditioning is possible by comparing the repair amount and repair tolerance with the quality variation. The user can also determine whether or not reconditioning can be completed within a specified maintenance period based on the repair lead time. The user can also confirm the cost of reconditioning in advance. In addition, in cases where reconditioning is difficult for a part, the user can also determine whether or not to remanufacture it.

[0081] In this way, the user can make an appropriate decision regarding the implementation of maintenance based on the displayed maintenance support information. As a result, the maintenance support system 100 can promote the extension of product life and the reduction of production volume, thereby contributing to a circular economy, etc.

[0082] <Modification> Repaired parts, etc. are not necessarily returned to the product that is the subject of maintenance for use. The maintenance support system 100 according to the modified example assumes a case in which the repaired parts, etc. are used in a product that is incorporated into a product with a higher maintenance priority, and presents useful information regarding the priority (hereinafter referred to as "maintenance priority information") to the user.

[0083] Specifically, the processor 20 identifies the product (device) in which the target parts, etc. to be maintained are used and the period of use based on the delivered device in the sales information, the maintenance record information, and the product design information. Note that the products in which the target parts, etc. are used include the target products described in the above embodiment.

[0084] In addition, the processor 20 uses the product design information of the identified product to identify replacement guidelines for parts, etc. based on a specified maintenance frequency. In addition, the processor 20 determines the priority of maintenance for replacing target parts, etc. used in the product with repaired parts, etc., based on the period of use and the replacement guidelines.

[0085] The processor 20 also generates maintenance priority information including the determined priority and displays it on the display. Note that the generation and output of the maintenance priority information may be performed, for example, after the above-mentioned step S80.

[0086] 9 is a diagram showing an example of maintenance priority information. As shown in the figure, the maintenance priority information includes items such as product name, usage period, replacement guideline, and priority.

[0087] The maintenance support system 100 according to such a modified example also presents information useful for determining whether to perform maintenance such as repairs to the user. As a result, the maintenance support system 100 can promote the extension of product life and the reduction of production volume, thereby contributing to a circular economy, etc.

[0088] In particular, by checking the items of the maintenance priority information, the user can decide to use the repaired parts, etc., for products with higher priority, etc. This allows the repaired parts, etc., to be used for appropriate products as needed, thereby extending the life of the products.

[0089] The present invention is not limited to the above-mentioned embodiments and modifications, and includes various other embodiments and modifications. For example, the above-mentioned embodiments have been described in detail to clearly explain the present invention, and the present invention is not necessarily limited to those having all of the configurations described. In addition, it is possible to replace a part of the configuration of one embodiment with the configuration of another embodiment or modification, and it is also possible to add the configuration of another embodiment to the configuration of one embodiment. In addition, it is possible to add, delete, or replace a part of the configuration of each embodiment with another configuration.

[0090] In addition, in the above explanation, the control lines and information lines are those that are considered necessary for the explanation, and not all control lines and information lines in the product are necessarily shown. In reality, it can be considered that almost all components are connected to each other. [Explanation of symbols]
