| 摘 要： | 本文在参考文献[1]的基础上研究了“批量q”及“订货点w”联合最佳的决策问题,得到了单位时间上平均总费用函数表达式S(w,q);证明了S(w,q)是严格凸函数,有唯一极小值点(w~0,q~0);找到了求解此极小值点的方法,证明了解法的收效性,以及S(w~0,q~0)最小值与S(w,q)最小值的差异性。

| Abstract: | Based on the reference, this paper studies theproblem of joint optimal policy for "lot q" and "order point w". Theexpression S(w, q) of the average total cost on a unit time is given.It proved that S(w, q) is a strict convex function with only one min-imal point (w~0, q~0); The method for finding this point is obtained,the convengence of the solution method is proved.The difference between the joint minimum S(w~0.p~0) and the miuimum S(w~*, q~?) is also proved. |
