Abstract: The shipper and the transportation enterprise are considered as a maximum profit system, but a reasonable and justified transportation arrangement must be searched out in order that both the shipper and the transportation enterprise can reach their maximum profit goals and be accepted by the market. In this paper, based on the incorporation countermeasure theory and aimed at the optimal system profit, the arrangement of transportation enterprise price regulation is researched, and an optimal systemprofitmodel is established and solved with K-T theorem. It is demonstrated by calculation examples that the method has great utility value.
