針對配送運作成本關鍵部分——平均運距作出的估計，在車輛路徑問題漸進最優(yōu)理論的基礎上，建立了一個平均運作成本最優(yōu)的規(guī)劃模型，從經濟的角度對運作策略作了簡要分析。與其他規(guī)劃模型不同，新建模型考慮了平均水平的概率特性及眾多實際因素，因而具有較好的實用性。

Abstract Based on the estimation of average distance derived from the theories of asymptotic optimization of VRP problems, this paper established a model to assist the programming and management of the distribution system for E-Shopping. The results can be used for management decision in aspects of economics. This model is characterized by the considerations on the probabilistic of real system and the conclusions are applied to management decisions under so much realistic consideration.
