具有复杂约束混料试验的渐近D-最优设计
发布时间:2019-06-08 06:52
【摘要】:复杂约束条件下试验设计区域极不规则,通常难以得到精确的最优设计.本文构造一种针对混料试验设计的随机搜索算法(MDRS),在具有复杂约束的区域内由Monte-Carlo方法产生一组初始点集,并通过MDRS算法迭代至逼近最优点集.通过实例验证,这种方法是有效的.它可以作为衡量其他设计的一个标准,即只有当给出的其他设计优于近似的最优解时才是有效.
[Abstract]:Under complex constraints, the experimental design area is very irregular, so it is usually difficult to obtain accurate optimal design. In this paper, a random search algorithm (MDRS), for mixing experiments is constructed, which is designed by Monte-Carlo method to generate a set of initial points in a region with complex constraints, and iterates to approximate the optimal set by MDRS algorithm. An example shows that this method is effective. It can be used as a criterion to measure other designs, that is, it is effective only if the other designs are superior to the approximate optimal solution.
