Abstract:

In the design of equipment experiments, the mixing of multi-type factors is very common, and there are complex constraint relations among the factors. For complex and irregular experiment space, a maximum projection coordinate exchange experimental design algorithm (MP-CE) in normalized constrained space is proposed. Firstly, typical factor constraints are defined and described in standardised terms. Then, a unified experiment space description method is presented to represent analytical constraints and non-analytical constraints, and construct normalized constrained experimental space. Then, the improved MP-CE algorithm is proposed according to the characteristics of normalized constrained experimental space to effectively addressing multi-factor mixed experimental design problems under complex constraints. Finally, a comparative study is carried out through an application example. The effectiveness and advantages of the proposed method are verified by calculating multiple evaluation indexes such as model prediction effect, space filling and optimality criterion.

Key words: design of experiment, multi-type factors mixing, maximum projection criterion, coordinate exchange, constraint space
