The Contract Design And Coordination Of Dairy Supply Chain With The Attendance Of The Third Party Logistics

Dairy Industry has made a spectacular progress in recent years, which has became an integral part of People’s Daily food demand. With the improvement of public health awareness, people in the consumption of dairy products not only focus on the price of dairy products, but also pay more attention to the quality. For example, dairy products transportation conditions, storage conditions, the fresh degree and so on. These put forward higher requirements for logistics service quality of the dairy products.Currently, dairy products mainly adopt the self-transportation in our country, due to the logistics lack of professionality and logistics construction can’t invest too much energy, thus can’t guarantee logistics service quality of dairy products, but the development of professional third party logistics of dairy products provides a powerful guarantee for the improvement of the logistics service quality. However, the addition of dairy products third party logistics gives an assurance of the service quality, at the same time, whether can realize the optimization of the dairy products’supply chain and asymmetric information problems because of third party logistics’information superiority, which need to be solved urgently. The study for these problems is of great significance to the harmonious development of dairy products supply chain. For the problems above, this article mainly studies the following several aspects.(1) In view of the selection and decision-making problem of the dairy supply chain structure, considered the two scenarios of whether the third party logistics involved in or not, the thesis set up Stackelberg game model respectively with dairy products production enterprise as the leader, dairy products dealers as the follower, giving an analysis of the relationship of logistics services cost coefficient and logistics service quality, logistics services cost coefficient and the demand for dairy products, total revenue of supply chain and logistics service cost sharing ratio, to provide a theoretical basis for decision makers of supply chain to select a better dairy supply chain structure.(2) In view of the coordination problem of dairy products supply chain with the participation of Third-Part Logistics, considered two different conditions of the third party logistics enterprise logistics service cost information symmetric and asymmetric, established supply chain coordination model of the third party logistics cost information symmetry and asymmetry respectively, giving an analysis of the influence to the logistics service quality, the demand for dairy products, the third party logistics enterprise profits, other members of the supply chain profit and the changes of the gross supply chain profit from the changes of Logistics service cost coefficient in two circumstances, to provide the theoretical basis to optimize the dairy supply chain logistics service quality and guarantee the coordination of dairy products supply chain.(3) In allusion to the lie behaviour of the third party logistics enterprise of dairy products, considered the prevention to the behavior, established the contract incentive mechanism and model based on the principle of Myerson, to give an analysis of the relationship between the transfer payment allocation proportion and the total income distribution, thus, to provide the basis for designing the best incentive mechanism, to prompt the third party logistics enterprise with information advantage to declare the true cost information, to realize the coordination of the dairy products supply chain finally.
