Abstract
In order to analyze the performance of Pull type production ordering systems against in-process factors, this paper constructs a model of multi-stage production-inventory system with two kinds of in-process factors, production capacity and machine breakdown. And this paper develops two models of Pull type production ordering systems with the difference of information used. Where, this paper considers the feedback of information about the difference between production order and actual production, that was occurred by in-process factors. With simulation experiments for the models, this paper clarifies the influence of in-process factors upon the amplifications of production quantity and inventory level.
