We propose a minirnax model with a "quadratic" recourse. In stochastic linear programming models, a decision maker has been assumed to know the probability distribution of random variables. Here we consider the case that the parameters of distribution are unknown. We impose the restrictions on the unknown parameters from the view point of a confidence region, and then seek a minimax solution that minimizes the worst case of the parameters. This model reflects the situation minimizing the

The analysis for a sufficiently large sample size and a numerical result are given. m The unknown parameter 8 is imposed the restrictions estimated by the confidence region S witn a certain significance level. We consider the worst case of the parameter 8 among S, and then minimize the objective function of Copyright © by ORSJ.
