摘要
经济运行带有不确定性和随机性,这些不确定性和随机性因素是造成决策者不能做出正确决策的原因之一。利用随机弹性概念,研究了不允许缺货的整批间隔进货模型和不允许缺货的分批连续进货模型中,一个采购周期内的总费用对最高库存量的弹性。给出了总费用弹性概率密度的一般表达式。通过实例证明了当最高库存量的分布特性已知时,总费用的弹性变化范围及变化范围的可信度。
Uncertainty and elasticity exist in economical operations, which are the main reasons that have made policymaker can not supply correct policies. On the basis of the concept of stochastic elasticity presented, under the conditions in which out-of-stock is not permitted and wholesale stock with goods at interval is demanded, and in which out-of-stock is permitted and continuously stock with goods in a batch is demanded, the elasticity of total cost of one purchase period is studied. The general expression of probability density of total cost is given. The example shows that elasticity distribution of total cost is defined completely and its change law and range are clean, when the distribution properties of the highest storage quantity are known.
