A plurality of basic items of product specifications on which to base the product design, defined as each specification item, and one or more specifications of the product designer is supposed to be taken by each specification item advance, set the constraint In a product configuration design support system that supports configuration design in which a configuration designer selects a specification value for each specification item of a design target product and completes the design within a range that satisfies the set specification value and constraint conditions . ,
In response to application to the product, for a particular specification item taking each particular specifications, as the constraint condition when in the constraint relationship that other specification items must take particular specification values, specification item Specification configuration information database configured in a tabular format with specification values, constraint conditions, and applicable product data ,
A specification management means for maintaining and updating the specification items and specification values of the product to be designed by the component designer;
The specification management means, already selected the specification item, and based on the specification value, searches on data records in the table the type described in the specification configuration information database, and other non-selection of the constraint condition is satisfied The specification items and specification values are determined as candidates to be shown to the component designer,
The product configuration design further comprising screen generation means for generating a configuration design screen for displaying the determined specification item and the specification value to a configuration designer and prompting the user to select a standard specification satisfying the constraint condition. Support system. A specification selection rule information database in which a default value for a specification item when the configuration designer omits the selection or a rule for setting a specification value by the system is recorded in association with the specification item and the specification value;
In the structure designer the configuration design screen, skip to choose their specifications specification item, when left up to the system accepts the discretion instruction, searching for the specification selection rule information database, the corresponding The product configuration design support system according to claim 1, further comprising means for automatically setting a specification value in accordance with default values to be set or rule information. Manages the relationship between the specification items and specification values described in the constraint conditions in a network, and determines whether or not the specification items and specification values can be applied in an order that does not break the chain of constraint relationships against the input of the configuration designer. or product configuration design support system according to claim 1 or claim 2, further comprising a design calculation means for calculating the specifications. When a configuration designer inputs a specification value that does not satisfy a constraint condition for a certain specification item, the combination designer searches for possible combinations of specification values of other specification items so as to satisfy the constraint condition, and presents the result. The product configuration design support system according to claim 1 , further comprising automatic specification setting means . 2. The product configuration design support according to claim 1, further comprising design calculation means for calculating an influence of selection / change before determining the specification value, and a screen generation means for presenting the influence to the user as an alarm. system. A matter information database including customer attributes, customer requirement specifications and specification selection history;
A specification arrangement information database describing the price for each specification value of the specification item and the lead time required for delivery;
Means for presenting a combination of the specification values for the specification items so as to satisfy the price and lead time requested by the customer included in the case information database with reference to the case information database and the specification arrangement information database ;
The product configuration design support system according to claim 1 , further comprising:   2. The product configuration design support system according to claim 1, further comprising means for editing the data of the specification configuration information database by a screen operation.   5. The product configuration design support system according to claim 4, further comprising means for editing the data of the specification arrangement information database by a screen operation. A screen control information database that holds display and selection methods of specification items of the configuration design screen as parameters , and means for changing the screen design of the configuration design screen with reference to data of the screen control information database; product configuration design supporting system according to claim 1, characterized in that it has. Design calculation means for holding classification information indicating whether the determined specification value comes from a status such as user arbitrary, default, automatic selection, etc., and the status of the determined specification value based on the classification information The product configuration design support system according to claim 1, further comprising screen generation means for presenting to a user. A configuration design reference means for referring to and comparing past specification configuration information or template information is further provided. By the configuration design reference means , a specification selection result is copied within an arbitrary range, and this is corrected to select a user. The product configuration design support system according to claim 1, wherein a process is supported, a plurality of selection results are compared, and a difference is displayed.
