While a base model has been determined for a product, in a system for performing a configuration designing operation of the product by setting a specification value to a specification item of the product, a product configuration design aiding system aids that a configuration designer can easily perform the configuration designing operation while following a restriction condition of a specification value of a specification item. A specification configuration information database is constructed which describes restriction conditions available for the specification values with respect to the specification item, and a configuration designing screen for inputting the specification values with respect to the specification item is displayed so as to conduct an input by the configuration designer.

System for aiding the design of product configuration

A specification plan of an order-made product suitable for a building structure plan is generated promptly. A WWW serverand a database serverare provided to the equipment designer's side. The database serverhas a drawing databasethat registers a CAD symbol for each product. A CAD symbol for each product includes: effective space information, which expresses a space to be secured for installation of the product; product name information expressing a name of the product; structure information expressing structural features (size, shape, etc.); product specification information; option data; etc. On the other hand, WWW serverhas a symbol generation data interface, through which requirements specification data for an order-made product can be received from a WWW client terminal, and a CAD symbol of the order-made product can be taken out from the side of the WWW client terminal.

In a design aiding method, a design aiding apparatus having the method, or a design aiding system possessing a plurality of such design aiding apparatuses for use in a field of computer software to facilitate a design process, there is determined, for a product having many variations of attributes and values thereof, an appropriate design procedure according to a state of design in a process of determining the attribute values of the product satisfying a request of a client. At occurrence of, for example, conflict during the design, the design procedure is guided for the user to obtain a design plan conforming to the request.

Method and apparatus for aiding of designing process

In order to derive optimum design specifications based on total evaluation performed on a product as a whole instead of individual design items during a process of determining design specifications involving a plurality of design items, candidates for the product specifications are selected by controlling design parameters for each of the design items in an integrated manner, computing values of a plurality of evaluation items evaluating candidates for the design specifications and performing total evaluation on all the evaluation items based on their computed values through collaboration among a plurality of design sections altogether auto-correcting all relevant design parameters quickly and relaxing as well as reassessing design constraints for a design parameter.

Method and apparatus for cooperated design

A product specification complex analysis system is provided which inputs product specifications of an external form and materials, design parameters determined by analysis and evaluation in the specifications, the range of the change of the parameters and a plurality of items of estimates as external input data, calls out and executes an evaluation program corresponding to each item of the estimates and stored in advance, from a group of evaluation programs whenever the item of the estimates is renewed, in order to sequentially evaluate the product specifications for each item of the estimates, determines the fluctuation of analysis results with respect to the change of the design parameters within designated ranges of changes, evaluates trade-off between the analysis results by changing the design parameters from the analysis results corresponding to the items of the estimates so as to make maximal evaluation values in an evaluation formula as an estimate function with weights comprising each of these analysis results, and can thus obtain optimum design parameters.

An object of the present invention is to provide a practical method for machining a sculptured surface. One of the characteristics of a concrete method for machining a sculptured surface so as to accomplish the object is that a patch table of a sculptured surface as surface information data for sculptured surface machining is configured so that a tool path can be generated using the inverse offset method for various surfaces such as a Bezier surface or a Ferguson surface and another characteristic is that over cutting during tool path generation on the basis of the inverse offset operation can be corrected.

Method and system for machining a sculptured surface

The present invention is applied to the design of a mold for a semiconductor or the like and provides a method for synthesizing analysis models, in which analysis programs corresponding to shapes and features of an object to be analyzed are registered in advance in a numerical analysis system, the analysis programs are made to correspond to partial shapes divided according to the shapes and features of the object to be analyzed and are partially modelled, whereas input and output items between adjacent portions are controlled on the basis of the positional relationship between the portions and input and output information of the analysis programs placed in correspondence to the portions. The invention further provides a flow analysis system for computing a flow state of material to evaluate a shape of a flowpassage, a flow control condition, material and the like, the system comprising input means for inputting a flowpassage shape of a mold, properties of material and flow control conditions, model synthesizing means for extracting a feature of the flowpassage shape, judging an adaptability with the already registered analysis model from the extracted features and synthesizing flow analysis models capable of analyzing the entire flowpassage, and program execution means for removing programs corresponding to the synthesized model to sequentially execute them.
