This paper from the view of transportation cost on the optimal, comprehensively considered the transportation
time and the modes of transportation capacity constraints, solve the problem of the ratio of three kinds of
transportation modes, i.e., road, waterway and railway with time windows. According to the transportation time
limits and capacity status, arranging transportation task with a minimum of logistics cost balance, was the basic
requirement to successful complete the task on time. This study also has some practical significance in reality
vehicle transport operation, the data of the algorithm is not static, and we can modify the corresponding
parameters according to the actual situation in practice, so as to guide the practical operation.
This paper only study the four nodes, namely Plant, VDC, VSC and distributor, between Plant and VDC, VSC
and distributor are road transport, in fact, we solve the allocation problem between the VDC and VSC. The actual
situation may be more complicated, because there may need transfer through the transfer point between VDC and
VSC, and even many times of transshipment, which requires to study more nodes to be further study.
