COMPONENT SELECTION METHOD, PROGRAM AND SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a component selection method which allows a user to prepare a simple plant model from a prototype, estimate impact of mounting of a component which is a material candidate and make an appropriate T-BOM selection while reducing the number of times of component replacement.SOLUTION: A variation of parameters is verified for a type of material (402). Component candidates showing a maximum or minimum properties are selected for each material to estimate a simple plant model (404). A combination of components selected in design is physically tested (406). It is determined whether the test result almost meets the design target (408). When the difference is within a prescribed range, the test is closed. On the other hand, if not, materials related to a direction where the gradient absolute value is the largest are selected (410), a candidate component whose sum of coefficient norms interpolated at each candidate position is the closest to the sum of coefficient norms of an initial set model is selected from among the selected materials and it is physically tested (412).
