This article discusses the problem of normal populations with unknown means and variance under simultaneous order restrictions, gives the iterative method based on the bootstrap, and compares the results of the simulative and traditional alternating iterative methods.%讨论了在半序约束下正态总体均值和方差的区间估计问题,给出了基于bootstrap方法的迭代算法,通过模拟与传统交错迭代算法的结果进行了比较.
