For example, in FIG. 6, the part ID "3" of the design ID "3" is associated with the equipment information 33, and it is found that new equipment needs to be introduced when the base is "Factory B". It can be seen that the quality (Q) at that time is "99%" from past results. Note that the item "quality (Q)" may be set based on past performance even if it is not necessary to introduce new equipment for assembling parts.

FIG. 7 is a diagram showing an example of the processing cost information 36. As shown in FIG. The processing cost information 36 indicates whether or not the parts are processed by the equipment and whether or not there is a worker when the target product is assembled using the parts required and if the equipment is required at a predetermined base.

Also, the processing cost [yen/design] for the product with the design ID “3” is calculated by the calculation unit 20 as “46” (=10+18+18).

Note that the storage unit 3 shows an example in which information such as strength information 31, parts information 32, equipment information 33, worker information 34, quality information 35, processing cost information 36, etc. are stored as separate data (tables). However, it is not limited to this. For example, all of these pieces of information may be stored in the storage unit 3 as one piece of data (table).

In addition, when there is a change in the equipment, the workers of the equipment, or the machining results of parts at each base, such information is updated as needed as the original data to be referred to for storage in the storage unit 3. shall be Further, each coefficient for calculating the processing cost of a part may be separately provided with data (table) for automatic setting according to a predetermined rule, or may be set individually by another method.

FIG. 8 is a diagram showing an example of a hardware configuration for implementing the design support device 1 of the present disclosure with a computer device 8 including a processor. As shown in FIG. 8, the computer device 8 includes a memory such as a CPU (Central Processing Unit) 801, a ROM (Read Only Memory) 802, a RAM (Random Access Memory) 803, and a storage device such as a hard disk for storing a program 804. 805 included. Further, the computer device 8 includes a communication I/F (Interface) 808 for connection to a communication network 813 and an input/output interface 811 for inputting/outputting data to/from a peripheral device 814 . In addition, the computer device 8 connects each device constituting the computer device 8 with an input device 809 and an output device 810 provided inside or outside the computer device 8 via a bus 812 .

The CPU 801 operates the operating system to control the entire computer device 8 that implements the design support apparatus 1 . Also, the CPU 801 reads programs and data from a recording medium 806 mounted in a drive device 807 or the like to a memory. The CPU 801 also functions as the processing unit 2 shown in FIG. 1, and executes processing or instructions in a flowchart shown in FIG. 9, which will be described later, based on a program.

The recording medium 806 is, for example, an optical disk, a flexible disk, a magneto-optical disk, an external hard disk, or a semiconductor memory. A part of the recording medium is a non-volatile storage device, in which programs are recorded. Alternatively, the program may be downloaded from an external computer (not shown) connected to a communication network.

The input device 809 is implemented by, for example, a mouse, keyboard, built-in key buttons, etc., and is used for input operations. The input device 809 is not limited to a mouse, keyboard, or built-in key buttons, and may be a touch panel, for example. The output device 810 is implemented by, for example, a display and used to confirm the output. In this embodiment, the design support apparatus 1 starts processing when it detects that the user has received a necessary operation related to product design from the input device 809 .

As described above, the design support device 1 shown in FIG. 1 is realized by the computer hardware shown in FIG. However, the implementation means of each unit included in the design support apparatus 1 of FIG. 1 is not limited to the configuration described above. The design support apparatus 1 may be realized by one physically connected device, or may be realized by two or more physically separated devices connected by wire or wirelessly. good. For example, input device 809 and output device 810 may be connected to computer device 8 via a network. In this embodiment, the storage device 805 or a storage device connected to the communication network 813 stores past product information and performance information such as facility information for assembling parts. Further, the storage device 805 stores various information necessary for design support as the storage unit 3 shown in FIG.

FIG. 9 is a flow chart showing the operation of the design support device 1. As shown in FIG. The design support apparatus 1 starts operating when the user registers (inputs) new design information for product assembly (step 901). For example, the user presses the design data input tab 10a on the input screen displayed by the design support apparatus 1 as shown in FIG.

Next, as an option, if there is a strength required for the product to be designed, the design support device 1 obtains the required strength according to the user's input (step 902). For example, on the input screen displayed by the design support apparatus 1 as shown in FIG. Select the part to set the request strength as follows. Further, the user inputs the designated intensity through the input section indicated by reference numeral 11d. After completing the specification of the intensity, the user presses the input completion button 11e to set the specified intensity for the product.

After that, for example, when the user presses the analysis execution tab 12a on the input screen displayed by the design support apparatus 1 as shown in FIG. 12, the operation of the strength confirmation unit 21 is started. Based on the necessary parts linked to the new design information input in step 901, the strength confirmation unit 21 searches for design parts and assembly methods that satisfy the parts in the new design information from the past results, and provides design support. Candidates for design information for The strength confirmation unit 21 performs strength calculation based on the design information obtained from the search results, and extracts one or a plurality of design information that satisfies the required strength for each site (step 903). At this time, after the strength is calculated, the strength confirmation unit 21 selects only the design information that also satisfies the requested strength input in step 902, and uses it as candidate design information. If there is no required strength input in step 903, the strength confirmation unit 21 does not consider the required strength, and based on the parts that are required to be linked to the new design information input in step 901, the past performance Search for design parts and assembly methods that satisfy the parts in the new design information, and extract candidate design information.

The design information extracted in step 903 and the new design information obtained in step 901 are stored in the storage unit 3 as strength information 31 and part information 32 as candidates for design information that may be used for design support. stored in The new design information obtained in step 901 is also stored in the storage unit 3 as design information. In the examples of FIGS. 2 to 6, it is assumed that design ID "1" is new design information, and design IDs "2" and "3" are design information possibly using past performance information. do.

After extracting possible design information by searching past results, the strength confirmation unit 21 determines whether the product design based on the new design information input in step 901 is greater than or equal to the required strength input in step 902 ( step 904). If the new design information is less than the required strength (step 904: No), the strength confirmation unit 21 checks the design information other than the new design information, that is, the design information extracted in step 903, in the following steps. (step 904). If the design of the product based on the new design information input in step 901 is also more than the required strength (step 904: Yes), the new design information input in 901 and the extracted in step 903 The design information is subject to calculation of the processing cost that can be performed in the following steps. It should be noted that step 904 is skipped if the requested strength is not input in step 902 .

The equipment confirmation unit 22 searches for information on available equipment from the past results of the facility corresponding to each piece of design information, and checks the equipment information 33 such as “jig/equipment”, “assembly content (commonality)”, and “assembly Add information about coefficients. Thereafter, based on the information added to the facility information 33, the facility confirmation section 22 determines whether or not newly introduced facilities and jigs are necessary (step 906). When newly introduced equipment or jigs are required, that is, when there are no equipment or jigs that have been used in the past (step 906: No), the equipment confirmation unit 22 performs processing for each part using the assembly coefficient. Calculate costs. For example, for a part with a design ID of "3" and a part ID of "3" in FIG.

The operator confirmation unit 23 refers to the results of the facility corresponding to each design information, personnel information, and other information as necessary, and obtains information such as the presence or absence of a user who can operate the facility, the presence or absence of a manual, etc. The operator information 34 is stored in the storage unit 3 by searching and adding information relating to the operator information 34, ie, "operator", "operator factor", and "manual". After that, the operator confirmation unit 23 uses the operator information 34 to determine whether or not there is an operator when newly introduced equipment or jigs are required (step 907). If there is no user (step 907: No), the worker confirmation unit 23 calculates the processing cost for each part using the worker coefficient. For example, for the part with design ID "3" and part ID "3" in FIG. 7, the calculated cost is further calculated as "9" (=5×1.2×1.5) by this process.

The operator confirmation unit 23 further adds information on the “training coefficient” that takes into account the presence or absence of the user to the operator information 34 . After that, the operator confirmation unit 23 uses the operator information 34 to determine whether there is a "training coefficient" set in consideration of the presence or absence of the operator (step 908). When the "training coefficient" is set, that is, when the worker does not need to be trained (step 908: No), the worker confirmation unit 23 calculates the processing cost for each part using the training coefficient. For example, for the part with design ID "3" and part ID "3" in FIG. 7, the calculated cost is further calculated as "18" (=5×1.2×1.5×2) by this process.

If there is a track record of processing and assembling parts in each piece of design information using designated equipment, the quality confirmation unit 24 refers to the data containing the past track record, and determines the quality (Q) as "Quality (Q)” is stored in the storage unit 3. After that, the quality confirmation unit 24 corrects the calculated cost of each part, taking into consideration the information about "quality (Q)" (step 907). For example, in the case of the part with design ID "3" and part ID "3" in FIG. showing. For the calculation cost of the parts by the quality confirmation unit 24, for example, a correction table showing the relationship between the non-defective product rate and the correction coefficient is provided separately, and based on the table, the processing cost of the parts is corrected according to the "quality (Q)". I do. In this correction table, correction coefficients are set so that when the "quality (Q)" is low, the processing cost is also reflected.

The calculation unit 20 calculates the processing cost in the design based on each piece of design information from the calculated cost of each part calculated in steps 906 to 909 . In the example of design ID “3” in FIG. 7, the calculated cost is calculated as 46 (=10+18+18) and recorded as “processing cost [yen/design]” in the processing cost information 36 . Subsequently, when the calculation unit 20 determines that the design information newly registered in step 904 satisfies the required strength input in step 902, the calculation unit 20 determines whether the processing cost in assembling the product based on the new design information is the minimum. A determination is made (step 910). If the processing cost in assembling the product based on the new design information is the minimum (step 910: Yes), the calculation unit 20 determines that the design information newly registered this time is the optimum design information. Design information is selected (step 911). FIG. 13 shows a display example by the design support device 1 when the requested strength is input as "100" in step 902, the new design information satisfies the requested strength, and the processing cost is the minimum.

On the other hand, when the transition is made from step 910 to step 912, the calculation unit 20 selects the design information that minimizes the processing cost from the design information other than the new design information input in step 901 as the optimum design information (step 913). FIG. 14 shows the design support apparatus when the requested strength is input as "200" in step 902, the new design information does not satisfy the requested strength, and the processing cost in the design based on other design information is the minimum. 1 shows a display example. Note that FIG. 14 shows an example in which the strength problem in the new design information is also displayed. FIG. 14 shows an example in which the design name "design 2" (design ID "2" in FIG. 2) is displayed as the optimum design information. In the example of FIG. 4, the display processing may be performed so as to display the base for assembling the products, which is "Factory B".

In FIG. 9, it was explained that the calculated cost of each part uses the "assembly coefficient", the "worker coefficient", and the "training coefficient", and is corrected by the "quality (Q)". is not limited to For example, the calculated cost of each part is one or two of the "assembly factor", "worker factor", "training factor", and "quality (Q)" with respect to the "standard processing cost". You may calculate using the above. Furthermore, the "assembly factor", "worker factor", and "training factor" have been explained as factors for the "standard processing cost", but they are not limited to the factors, and some correction can be made to the "standard processing cost". Anything is fine.

The worker information 34 shown in FIG. 5 also includes information on the delivery date, but if it is considered that the cost is affected even if the delivery date is long, the calculation unit 20 further corrects the calculated cost for the part by taking into account the "delivery date". You can

In this embodiment, assembly and processing of parts required for a product are shown as an example, but design support for manufacturing including assembly and processing is also possible.

FIG. 15 is a diagram showing a minimum configuration diagram of a design support device according to one embodiment of the present invention. The design support device 1 includes at least a calculator 20 . The calculation unit 20 extracts design information including part information related to parts used for the product, using new design information for the product and past performance information based on the new design information. Using the processing cost for assembling the parts for the product calculated from the design information that allows the design of the product, taking into account the information on the worker who can handle the equipment associated with the part information of each design information to select the most suitable design information for said product.
