Parts list system used for part number management and method for preparing the same

Abstract

A method of preparing parts list system used for part numbers management, composed of a parts table database and a parts list controller. The parts table database includes a parts list which stores a state data and a part number data. The state data indicates a progress state of a part. The part number data includes a number of the part as an identifier. The method comprises preparing a part list storing the state data and part number data, setting the state data to indicate permission to change a part number, assigning a tentative part number, setting the state data after changing design of the part, defining the tentative part number as a normal part number, and checking validation of the tentative part number versus used part numbers and whether the tentative part number complies with predetermined rules for each part number data.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001]This is a divisional application of application Ser. No. 10 / 394,567 filed 21 Mar. 2003, currently pending; this application also claims the benefit under 35 USC 119 of Japanese Application Number 2002-084504, filed 25 Mar. 2002, and the entire subject matter of this priority document, including specification, claims and drawings, is incorporated by reference herein.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to a parts list (parts table) system on a computing system for managing a part configuration and the like of parts used in a product, and a method of preparing a parts list. More particularly, the present invention relates to a parts list system for preparing and managing a parts list and controlling a linkage to another data and the like, and a method of preparing a parts list.[0004]2.

AI Technical Summary

Benefits of technology

[0013]Therefore, an object of the present invention is to provide a system and method for managing part numbers continuously from a planning / scheduling stage to a designing stage.

[0016]It is advantageous if the parts list controller allows the change of the part number data, when the state data indicates permission of the change of the part number data.

[0021]It is advantageous, when the part number data is changed to the tentative part number data, if the parts list controller checks validation of the tentative part number data by comparing the tentative part number data with a previously used part number data.

[0022]It is advantageous, when the part number data is changed to the tentative part number data, if the parts list controller checks validation of the tentative part number data by checking whether the tentative part number complies with a predetermined rule of the part number data.

Problems solved by technology

And, even if the tentatively assigned part number (referred to as [tentative part number]) or a part configuration data are set at a planning / scheduling stage, they cannot be directly used at the designing stage.

Thus, the data such as the tentative part number and the part configuration data at the planning / scheduling stage cannot be directly and continuously shifted to new parts table at the designing stage.

Hence, it takes a long time to get the opinion and the request about the part table.
