本文研究了在给定两个随机模型先验测度r下的q分量二阶可加混料模型稳健D-最优设计.依据Kiefer次序下完备集的结果且结合稳健D-最优准则,给出了二阶可加模型稳健D-最优的相关理论,并得到了四分量可加模型稳健D-最优(∈)α:=αr*(∈)1*+(1-αr*)(∈)2*,且利用等价性定理证明了(∈)αr*为稳健D-最优设计.同时基于αr*与先验测度r的关系,介绍了先验测度r选择的效率最大最小原则,得到了四分量二阶可加模型的最优先验测度r*,且比较了四分量二阶可加混料模型稳健D-最优设计与D-最优设计的效率.“,”In this paper,we investigate the robust D-optimal designs of second degree additive mixture model under given prior of two random models.By using complete class result under Kiefer order and robust D-optimal criterion,we give the robust D-optimal theory and gain the robust D-optimal designs (∈)αr* =αr*(∈)*1 + (1-αr*)(∈)2* of four component additive model.Also,we prove (∈)αr* is robust D-optimal designs by using equivalence theorem and based on the relationship of αr* and r,we introduce the maximin efficiencies principle and gain the optimal prior r* of four component additive model.Also,we compare the robust D-optimal designs with D-optimal designs about the efficiency of seconde-degree additive mixture model.
