摘要:
利用自有车辆资源，在整合外协车辆资源基础上构建散装水泥运输体系，并辅以系统的管理，是散装水泥企业物流发展的有效模式。确定合理的自有车辆规模是这一模式下降低企业物流成本的有效措施之一。本文在考虑自有车辆和外协车辆的服务水平差异和客户不满意带来的有形和无形损失以及外协车辆的可获得概率基础上，建立成本最小模型并给出了模型的求解方法，最后结合算例计算出某散装水泥企业合理的自有车辆数量。
The model of the combination of bulk cement
enterprise owned vehicles and leased vehicles has been adopted popularly in our country. Configuring a reasonable fleet size
of the bulk cement enterprise is one of the measures to effectively reduce the
cost of bulk cement logistics. This paper analyzes the supply and demand
characteristics of the bulk cement transport, thereby getting statistics which reflect
the use status of bulk cement vehicles more accurately. Considering the difference
of service levels between owned vehicles and leased vehicles and the losses caused
by customer dissatisfaction, this paper establishes a minimum-cost model and
solution methods, and calculates the reasonable size of fleet owned by bulk
cement enterprise through examples.
