SOME COMMENTS ON “A SYSTEMS PERSPECTIVE ON MATERIALS REQUIREMENTS PLANNING”*
批评了Morecroft关于MRP问题的文章，指出其仅证明MRP不恰当应用于现有生产系统会导致不良绩效，并讨论了四个问题领域，提出替代方法。
ABSTRACT We believe there are some serious deficiencies in the Morecroft article on MRP problems which appeared in a recent issue of this journal. The article, at the most, shows that MRP, inappropriately imposed on an existing production system, can result in undesirable system performance. This does not represent a new or startling conclusion. Four problem areas in the article are discussed, and suggested alternative approaches are offered.
