摘要
研究了二五混水平U型设计在Lee偏差下的均匀性,利用两种不同的新方法,即CHATTERJEE和HU的方法得到了二五混水平U型设计的两个下界,并将它们综合成一个下界,同时以数值实例验证了该综合下界是紧的,且优于以往文献中的下界.
The uniformity of mixed two and five level U-type designs in terms of Lee discrepancy is focused on.Two new methods of CHATTERJEE and HU are used to get two new lower bounds of mixed two and five level U-type designs,and a syntheticlower bound is derived.Numerical examples are also provided to verify that the synthetic lower bound is tight and better than the old one inexisting literature.
