Method for optimized design using robust design method and computer readable record medium on which a program therefor is recorded

摘要

The present invention relates to an optimal design method using robust design techniques. A quadratic orthogonal array table, a quadratic system orthogonal array table, a 5-level system orthogonal array table, a multilevel system orthogonal array table, and a complex level system orthogonal array table. An array table selection step (S1); (S3) a step of inputting the number of iterations of the experiment value (S4), checking the quality characteristic value (S5), and selecting the orthogonal array table (S6), a minus characteristic (S7), and a mesh characteristic (S8); A variance analysis step (S10) for statistically analyzing the significance of fluctuation of all factors and the significance of factors, respectively, after selecting the factor (S9); When the execution button is selected (S11), a box plot (S12) for outputting an analysis result in a multidimensional manner at optimum level, a test graph screen (S13) and a factor effect diagram (S14) . Therefore, by using the robust design method, it is possible to minimize the loss from the development stage to the shipment stage of the new product and to optimize the quality control to improve the reliability of the product, thereby reducing the quality loss and the manufacturing cost.
