Patent ID: 7437269

Claim:
A system for evaluating reliability of a component, where said system evaluates credibility of a constituent information and a conformity of a candidate component to environmental regulations, for composing a product, comprising: an input unit; an output unit; a processing unit; and a memory unit, wherein the memory unit comprises: a component basic information table which retains identification information that distinguishes each item of a component; a constituent information table which retains information on constituents contained in the component and a content of each of the constituents; and an environmental qualification information table which retains information on constituents contained in the component for each item and a investigation result of conformity of the component to environmental regulations by establishments, and wherein the processing unit comprises: means which accepts selection of a target component through the input unit; means which accepts identification information that classifies components similar to the target component through the input unit; means which extracts a component similar to the target component based on the identification information of classified components similar to the target component by referring to the component basic information table and the constituent information table, and calculates constituents contained in the similar component and a content of each of the constituents; means which calculates each of the constituents contained in the target component and the content of each constituent, based on the content of each constituent of the component similar to the target component, which is obtained from the constituent information table, the content of each constituent being weighted based on a number of establishments that investigated the similar component, which is obtained from the environmental qualification information table; means which evaluates credibility of the evaluation of the conformity to environmental regulations based on a difference between the content of the constituent in the target component and the content of the constituent in the similar component, the constituent being used for the evaluation of the conformity to environmental regulations among the constituents contained in the target-component; and means which evaluates a conformity of the target component to environmental regulations by using the number of establishments that have already investigated the similar components and a total number of the similar components with a result of a qualification “pass ”, which are obtained from the environmental qualification information table; wherein the output unit outputs the result of the conformity/credibility evaluation.
