信息更新下的物流服务订单分配

提出一个多期多任务的多目标动态整数规划模型,通过引入方案锁定期和带服务质量目标控制机制,进一步给出了存在信息更新的多次订单分配规划模型.通过参数试验,把带服务质量控制目标机制的模型与采用线性权重法的多目标规划模型以及服务质量约束的规划模型进行比较.结果表明:带服务质量控制目标机制的订单分配模型和控制策略在确保满足服务质量要求的基础上,同时能够较好地兼顾成本目标,并且可操作性强,能够达到满意的效果.

Service Order Allocation Based on Multi objective Dynamic Programming

This paper analyzes how an individual logistic service integrator distributes its orders to the functional service suppliers in service supply chain. We introduce a dynamic integer-programming model with multiple tasks and targets, in multiple periods. An example is given to prove the feasibility of the model. We also propose an updating model to schedule order distributions in multi-periods, with the introduction of the mechanism of executing part of the solution then adjusting according to the updating information. We conduct a simulation. Based on a comparison between the linear weights MOP model and the service constrain model, the simulation result demonstrates that our model generates a lower cost while ensuring the satisfaction of service requirement.
