The designer inputs the design conditions of the product to be designed based on the customer's specification requirements. The design support device 10 receives the input of the design condition (step S101), and acquires the design condition input by the designer. Specifically, the designer activates the screen of the user interface unit 410 and registers the conditions in each item of the design conditions.

Specifically, when the design evaluation processing unit 130 receives the design change information, it determines that it is necessary to update the work evaluation model DB 310 (step S108; Yes), and updates the work evaluation model DB 310 (step S109). .. When the update of the work evaluation model DB 310 is completed, the design evaluation processing unit 130 notifies the work primary evaluation processing unit 140 of the identification information of the design model determined to be adopted based on the design evaluation information. On the other hand, when the design evaluation processing unit 130 does not receive the change information and determines that it is not necessary to update the work evaluation model DB 310 (step S108; No), it determines that the work evaluation model DB 310 is not updated and is adopted. The identification information of the designed design model is notified to the work primary evaluation processing unit 140.

On the other hand, when the design evaluation processing unit 130 determines that there is no adopted design model (step S107; No), the design evaluation processing unit 130 returns to step S101 and accepts the input of the design conditions. The designer changes the conditions such as the design conditions and the number of design models extracted by the model extraction processing unit 120, and inputs the design conditions again.

The work primary evaluation processing unit 140 receives input of primary workability evaluation information of the design model from the worker (step S110). Specifically, the work primary evaluation processing unit 140 notifies the user interface unit 410 of the design model identification information notified by the design evaluation processing unit 130, and displays an interface screen for receiving the primary workability evaluation information. The builder decides whether to input or change the primary workability evaluation value and adopt the displayed design model based on the information such as the design information of the design model displayed on this interface screen and the workability evaluation information. Then, enter the primary workability evaluation information including the information.

When the work primary evaluation processing unit 140 acquires the primary workability evaluation information, it determines whether or not there is an adopted design model (step S111). When the work primary evaluation processing unit 140 determines that there is an adopted design model (step S111; Yes), it notifies the work evaluation model DB 310 of the identification information of the design model evaluated to be adopted, and the work evaluation model DB 310 is evaluated to be adopted. Is stored (step S112).

Next, the work primary evaluation processing unit 140 determines whether or not it is necessary to update the work evaluation model DB 310 (step S113). Specifically, the work primary evaluation processing unit 140 compares the input primary workability evaluation value with the primary workability evaluation value stored in the work evaluation model DB 310, and when it is determined that there is a difference, the work evaluation model. It is determined that the DB 310 needs to be updated (step S113; Yes), the primary workability evaluation value stored in the work evaluation model DB 310 is overwritten with the input primary workability evaluation value, and the primary work evaluation model DB 310 is primary. The workability evaluation information is updated (step S114). Next, the work primary evaluation processing unit 140 determines whether or not the other design model stored in the work evaluation model DB 310 has the same items as the items of each manufacturing process of the design model that has received the input of the primary workability evaluation value. The primary workability evaluation value of the manufacturing process of another design model determined to have the same item is updated to the primary workability evaluation value of the design model that accepts the input of the primary workability evaluation value. When the update of the work evaluation model DB 310 is completed, the work primary evaluation processing unit 140 ends the processing. In step S113, when the work primary evaluation processing unit 140 determines that there is no difference between the input primary workability evaluation value and the primary workability evaluation value stored in the work evaluation model DB 310, the work evaluation model DB 310 is updated. It is determined that there is no need to do so (step S113; No), and the process ends.

On the other hand, when the work primary evaluation processing unit 140 determines that there is no adopted design model (step S111; No), it returns to step S101 and accepts the input of the design conditions.

As described above, the design support device 10 automatically selects a design model that satisfies the design conditions based on the required specifications and takes workability into consideration. The designer and the operator can evaluate the selected design model and determine the design model to be the design proposal.

Next, the operation of the design support device 10 after manufacturing the selected design model product will be described with reference to FIG. Specifically, a process of updating the work evaluation model DB 310 based on the secondary workability evaluation information that evaluates the manufacturing performance by the worker will be described.

The work secondary evaluation processing unit 150 receives the secondary workability evaluation information that evaluates the manufacturing performance by the worker after the product of the adopted design model is manufactured (step S201). Specifically, the builder displays an interface screen that accepts the input of the secondary workability evaluation value, and inputs the actual value of the workability evaluation value after manufacturing.

Next, the work secondary evaluation processing unit 150 determines whether or not it is necessary to update the work evaluation model DB 310 (step S202). Specifically, when the work secondary evaluation processing unit 150 compares the input secondary workability evaluation value with the secondary workability evaluation value stored in the work evaluation model DB 310 and determines that there is a difference. It is determined that the work evaluation model DB 310 needs to be updated (step S202; Yes), and the secondary workability evaluation value stored in the work evaluation model DB 310 is updated to the input secondary workability evaluation value for work. The secondary workability evaluation information of the evaluation model DB 310 is updated (step S203). Next, the work secondary evaluation processing unit 150 has the same items as the items of each manufacturing process of the design model in which the other design models stored in the work evaluation model DB 310 have received the input of the secondary workability evaluation value. The secondary workability evaluation value of the manufacturing process of another design model that is judged to have the same item by searching for whether or not it is the secondary workability evaluation value of the design model that accepts the input of the secondary workability evaluation value. Update to. When the update of the work evaluation model DB 310 is completed, the work secondary evaluation processing unit 150 notifies the work evaluation calculation processing unit 160 of the update. In step S202, when the work secondary evaluation processing unit 150 determines that there is no difference between the input secondary workability evaluation value and the secondary workability evaluation value stored in the work evaluation model DB 310, the work evaluation model It is determined that it is not necessary to update the DB 310 (step S202; No), and the work evaluation calculation processing unit 160 is notified to that effect.

The work evaluation calculation processing unit 160 compares the primary workability evaluation value of each manufacturing process and the secondary workability evaluation value stored in the work evaluation model DB 310, and when it is determined that there is a difference, the work evaluation model DB 310 is used. Perform the workability evaluation comparison process to be updated (step S204). Specifically, the work evaluation calculation processing unit 160 compares whether or not the difference between the primary workability evaluation value and the secondary workability evaluation value is equal to or greater than the threshold value set by the work evaluation calculation setting unit 260 (step S205). If it is equal to or greater than the threshold value, it is determined that there is a difference (step S205; Yes). Next, the work evaluation calculation processing unit 160 updates the primary workability evaluation value of the work evaluation model DB 310 to the value of the secondary workability evaluation value (step S206), and ends the process. On the other hand, when it is determined that there is no difference (step S205; No), the work evaluation model DB 310 is not updated and the process ends.

As described above, the design support device 10 updates the work evaluation model DB 310 based on the workability evaluation information after the product is manufactured. As a result, from the next time onward, the design support device 10 can select a design model based on the updated workability evaluation information.

As long as it does not deviate from the gist of the present disclosure, it is possible to select the configuration described in the above embodiment or change it to another configuration as appropriate.

In the present embodiment, the process is executed by one design support device 10, but the system configuration is arbitrary. For example, the function of the design support device 10 may be realized by a system including a user terminal that displays an interface screen that accepts user input, a processing unit 100, and a server device that realizes the functions of the setting unit 200. Further, the system configuration may include a plurality of user terminals.

Further, the information stored in the work evaluation model DB 310 may be collectively managed by a cloud server existing on the network, and the processing unit 100 may access the cloud server to read and write the information as needed. In this case, the design support device 10 does not have to include the work evaluation model DB 310.

In the above embodiment, the work primary evaluation processing unit 140 has decided to acquire information on whether or not to adopt the design model from the worker, but the work primary evaluation processing unit 140 may determine. Specifically, the workability primary evaluation setting unit 240 sets a threshold value for the workability total evaluation value or the workability evaluation value of each manufacturing process, and the workability primary evaluation processing unit 140 adopts or not depending on whether or not the threshold value is satisfied. To judge. For example, the work primary evaluation processing unit 140 may determine that the design model is adopted when the total workability evaluation value is equal to or higher than the threshold value, or when the workability evaluation value of all manufacturing processes is equal to or higher than the respective threshold values. Alternatively, if the total workability evaluation value is less than or equal to the threshold value, or if the workability evaluation value of any of the manufacturing processes is less than or equal to the threshold value, it may be determined not to be adopted.

Further, among the design models stored in the work evaluation model DB 310, a process of excluding the design model from the selection target of the model extraction setting unit 220 may be included. Specifically, the design model displayed on the interface screen may be displayed with information for selecting whether or not to exclude the design model from the future design model extraction processing target, and the user may be allowed to select the design model. The table data of the work evaluation model DB 310 is provided with an item for inputting information on whether or not to exclude from the design model extraction processing target in advance, and the model extraction setting unit 220 confirms and extracts the item of the table data. It is sufficient not to select the design model in which the information to be excluded from the processing target is input.

Further, the design support device 10 can be realized by using a normal computer system without relying on a dedicated device. For example, a program for realizing each function of the design support device 10 is stored in a recording medium such as a computer-readable CD-ROM (Compact Disc Read Only Memory) or a DVD-ROM (Digital Versailles Disc Read Only Memory). By distributing this program and installing this program on a computer, a computer capable of realizing each of the above-mentioned functions may be configured.

Further, when each function is realized by sharing the OS (Operating System) and the application, or by cooperating with the OS and the application, only the application may be stored in the recording medium.
