The Calculation of Effect and the Anticipant Estimation of Index´s Value in Orthogonal Design

The most superior production conditions that meet the targets’ needs can be selected after the visual and variance analysis of orthogonal design effects. But before the verification test, the optimal production conditions selected, the possible target’s value and the range of the targets haven’t been got. Based on the data structure of upright design experiment, the mathematical model of orthogonal table head design can be set up under some experimental conditions, and the effect value estimation of every parameter can be got according to the method of evaluation in differential. The theoretical estimation and interval estimation can be carried out in advance through the introduction of the process of effect calculation and the theoretical analysis of target’s value with the optimal plan in upright design test.
