利用高等数学中使一次微分为零,求最小值或最大值的方法来研究管理中的问题,作出最佳的技术上和经济上的决策,是管理科学中寻求最优化方案的有效方法之一。它的应用范围广泛,计算简便。下面介绍如何运用这种方法建立模式及其应用问题。一、建立数学模式的基本原理早在1915年,所谓“科学的库存控制”的最早的方法之——经济批量的确定,就是按照微积分中求极值的原理建立起来的。我们也就从经济订货批量(EOQ),人们所熟悉的问题来分析。我们知道,订货批量,对产品成本从两个相反的方向产生影响。有一些成本因素,如库存保管费用、资金占用的利息等等,随着批量的增减成正比例变化,另一些成本因素,如单位产品中订货费用,则随着批量的增减而成反比例变化。还有一些费用,如单位产品的材料
It is one of the effective methods to seek the optimal solution in management science by using the method of making the first derivative to zero, and finding the minimum or maximum value in higher mathematics to study the problems in management and make the best technical and economic decisions. . It has a wide range of applications and is easy to calculate. Here’s how to use this method to establish the model and its application problems. First, the establishment of the basic principles of mathematical model As early as 1915, the so-called “scientific inventory control” of the earliest methods - the determination of economic batches, is based on the principle of seeking the extremes of calculus built up. We also analyze from the economic order volume (EOQ) that people are familiar with. We know that order quantities have an impact on product costs from two opposite directions. There are some cost factors, such as inventory storage costs, interest borne by funds, etc., which change in proportion to the increase or decrease in the volume. Other cost factors, such as the order cost in the unit product, are inversely proportional to the volume increase or decrease. . There are some costs, such as the material of the unit product
