| 摘 要： | 提出经济订购批量(EOQ)基本模型中参数的估计公式,假定这些参数的实际取值是一定范围内的未知数,并可能随时间而变化.从EOQ的灵敏性分析中引出两种可获得“满意解”的估计方法,进而给出依据最大最小准则和最小期望值准则进行参数估计的计算公式.文末辅以实例说明.

| Abstract: | This article provides formulas for estimating the parameters to be used in the basic EOQ lot-size model. The analysis assumes that the true values of these parameters are unknown over known ranges and perhaps nonstationary over time. Two measures of estimator "goodness"are derived from EOQ sensitivity analysis. Formulas are given for computing the minimax choice and the minimum expected value choice for the parameter estimates using both measures of estimator "goodness". A numerical example is included. |
