Design and manufacturing management system, method, and program

A design and manufacturing management method comprising:

• producing a production plan in a production plan server machine and instructing a design management server machine to design a product based on the production plan;
• connecting a manufacturing management server machine to a design management server machine using a feedback management loop;
• manufacturing designed parts;
• feeding back design change verification database information;
• the design management server machine performing:
• managing a design drawing of a product, which has been created by means of computer aid, by storing the design drawing in a design drawing database;
• managing an E-BOM created from the design drawing by storing the E-BOM in an E-BOM database, and for notifying design completion;
• the manufacturing management server machine performing:
• requesting confirmation when receiving the design completion notice, and managing a M-BOM, to which preparation information including an order instruction and a manufacturing instruction of a part is added and which has been created in accordance with the E-BOM after a confirmation response is input, by storing the M-BOM in a M-BOM database;
• managing design change verification information which has been created in accordance with the preparation information of the M-BOM by storing the design change verification information in the design verification database;
• and
• causing design change permitted range and forbidden range to be displayed, upon design change of the product, in accordance with the design change verification information which is feedback information from the manufacturing management server machine and has been created and updated in the manufacturing management server machine and is in the design change verification database;
• wherein the design change permitted range and forbidden range are determined in accordance with a progress state of the manufacturing instruction and the order instruction of the part in the preparation information, and the design change verification information is updated.

A computer-readable storage medium which stores a program for causing computer servers of a design management system to execute operations comprising:

• producing a production plan in a production plan server machine and instructing a design management server machine to design a product based on the production plan;
• connecting a manufacturing management server machine to a design management server machine using a feedback management loop;
• manufacturing designed parts;
• and
• feeding back design change verification database information;
• the design management server machine performing:
• managing a design drawing of a product, which has been created by means of computer aid, by storing the design drawing in a design drawing database;
• managing an E-BOM created from the design drawing by storing the E-BOM in an E-BOM database, and for notifying the manufacturing management server machine of design completion;
• and
• the manufacturing management server machine performing:
• requesting confirmation when receiving a design completion notice from the design management server machine, and managing a M-BOM, to which preparation information including an order instruction and a manufacturing instruction of a part is added and which has been created in accordance with an E-BOM in an E-BOM database after a confirmation response is input, by storing the M-BOM in a M-BOM database:
• and
• managing design change verification information which has been created in accordance with the preparation information of the M-BOM by storing the design change verification information in a design verification database;
• causing design change permitted range and forbidden range to be displayed, upon design change of the product, in accordance with the design change verification information which is feedback information from the manufacturing server machine and has been created and updated in the manufacturing management server machine and is in the design change verification database,
• wherein the design change permitted range and forbidden range are determined in accordance with a progress state of the manufacturing instruction and the order instruction of the part in the preparation information, and the design change verification information is updated.
