| 摘 要： | 利用随机局部弹性理论,研究了允许缺货的随机存储模型中,总费用对随机采购量与随机采购周期的随机局部弹性.通过求解雅各比行列式,给出了总费用对随机采购量和随机采购周期的随机局部弹性的联合概率密度.进一步,当随机采购量和随机采购周期的分布特性已知时,总费用的弹性分布和弹性变化范围就完全被确定.

| Abstract: | In case the purchase is undertaken in goods out of stock is permitted, stochastic partial elasticity of total cost related to random purchase quantity and purchase period are studied, using stochastic partial elasticity theory. Solution by Jacobi determinant, the joint probability density function of stochastic partial elasticity of total cost related to random purchase quantity and purchase period is obtained. Further, if the distribution characteristics of the random purchase quantity and purchase period are known, stochastic elasticity distribution and elasticity rariable range of total cost is determined. |
