基于货物时间价值的物流网络最优配送路径模型研究

本文构建了物流配送网络中货物时间价值相关的最小配送费用路径模型，并研究了其算法。模型把整个配送过程分为运输过程和装卸过程，并且考虑了由于运输过程和装卸过程时间延迟造成的货物价值损失，这也是和其它类似成本路径模型最大的区别。该模型算法可以利用计算机自动完成，不受物流配送网络大小和节点的限制，并保证算法的正确性。

A Logistics Minimum Cost Distribution Path Model and Algorithm Depending on Freight Time-value

A time-value-dependent logistics minimum cost admeasure path model for a logistics network was constructed, and its algorithm was studied. The model divided a delivery process into two parts, that is, the transportation and the loading and unloading processes, meanwhile, the lost due to the time delays in the two processes was considered. This is the great difference from the other models. The efficient implementation was designed that allowed path computating on a realistic large-scale network without limiting the transport node number. The correctness of the algorithm was gurrantied.
