基于多目标动态规划的运输链合作伙伴选择

Cooperative Partner Selection of Transportation Chain Based on Multi-objective Dynamic Programming

联合运输过程中特定运输链混合型任务的合作伙伴如何进行系统选择,是实现联合运输的基础问题之一.将运输链看作由合作伙伴组成的运输系统,首先确定优选过程的阶段、状态变量、决策变量和递推方程,其次是通过对备选合作伙伴不完全信息的标准化和点值化处理,再对运输链合作伙伴选择采取逆序法递推计算,得到最优策略.实证分析表明,此方法可操作性强,计算方法简便且具有较高的可靠性.

The key step of realizing combined transport is to determine the cooperative partners of mixed task in specific transportation chain quantitatively and systematically in the combined transport process.By taking the transportation chain as a transport system that consists of transportation partners,firstly,the optimization phases,state variables,decision variables and recursive equation were determined,then through the standardized processing of the incomplete information of optional partners and making the point digitized,the cooperative partner selection values of transportation chain were calculated by using recursive reasoning algorithm,and the optimal strategy was presented.The positive analysis proves that this selective method has the characteristics of better maneuverability,easer computation and higher reliability.
