Patent ID: 7349750

Claim:
A computer implemented method for optimizing a structure of an industrial product, comprising: selecting a plurality of control factors from among a plurality of manufacturing parameters affecting a target characteristic of the industrial product, which is scheduled to be manufactured by a sequence of manufacturing processes, the control factors being related to a plurality of manufacturing conditions; setting a plurality of levels to the respective control factors; selecting a reference characteristic having a trade-off relation with the target characteristic from among a plurality of characteristics of the structure; setting a reference value to the reference characteristic; selecting a prior adjustment factor affecting the reference characteristic from among the manufacturing parameters, the prior adjustment factor being different from the control factors; creating conditions for a plurality of experiments assigning a plurality of combinations of the levels to the respective control factors so that, with respect to each level of a specific control factor among the control factors, all levels of other control factors are evenly combined; determining an adjustment value of the prior adjustment factor so that each of characteristic values of the reference characteristic obtained by the experiments conforms substantially to the reference value; determining experimental characteristic values of the target characteristic corresponding to each of the experiments using the adjustment value; and determining an optimal value of the target characteristic and an optimal combination of the levels based on the experimental characteristic values of the experiments, the optimal combination providing the optimal value.
