Abstract
In order to suppress the variances of the produciton and inventory levels of the multi-stage production inventory system, this paper analyzes the influnces of the autocorrelation coefficient of demand, the produciton capacity, and the standard deviation of down time upon the amplificxations of the produciton and inventory levels. Where the production ordering systems dealt in this paper are two types proposed by the previous paper[7]. As a result, it was clear an effective produciton ordering system according to the levels of the autocorrelation coefficient of demand, the production capacity, and the standard deviationof down time.
