基于理性預(yù)期均衡的物流服務(wù)供應(yīng)鏈任務(wù)分配研究
[Abstract]:Ability allocation decision is one of the most important decisions in supply chain strategy. In the face of multiple logistics service providers, it is the key to ensure the long-term stable operation of the logistics service supply chain that how the logistics service integrators carry out the reasonable assignment of demand order tasks. At present, the research on task allocation of supply chain is mainly focused on product supply chain, but less on service supply chain. In the process of constructing task assignment model, only time, cost and other objectives are considered. Especially in the previous research of supply chain task assignment, enterprises involved in task assignment often passively accept orders. However, in the actual order allocation, the participating enterprises have strategic behavior, they will start from their own profit, satisfaction and other aspects to decide whether to participate in task allocation. This behavior has an important impact on the outcome of task allocation. Therefore, this paper takes logistics service supply chain as the research background, applies the behavior operation theory to the supply chain task allocation, considers various strategic behaviors of the provider in the task assignment process, based on the rational expectation equilibrium theory. Taking the total cost of the integrator, the satisfaction degree of the provider and the ability matching degree as the objective function, the task assignment model of the logistics service supply chain is constructed. It provides the necessary theoretical reference for logistics enterprises to make scientific decision in the actual logistics practice operation. This paper first gives the research background and research status, analyzes the development of logistics service supply chain theory, then combs the supply chain task allocation, rational expectation equilibrium, supplier competition and other theoretical results. This paper summarizes the existing references, points out the shortcomings of the research, and lays a theoretical foundation for the full study. Then, from the strategic behavior of task allocation participants, this paper studies four aspects: (1) in the first part of the thesis, we consider the expected behavior of providers in the task allocation of logistics service supply chain. This behavior is represented by mathematical language in the model, and the influence of uncertainty, expected discount coefficient and provider goodwill on the distribution results is analyzed. (2) based on the previous research, the paper analyzes the effect of uncertainty, expected discount coefficient, and provider goodwill on the distribution results. (2) on the basis of previous studies, Further consider the construction of task assignment model in competitive environment, and through numerical analysis to explore the intensity of competition, increase the impact of different types of providers on task allocation. (3) in the case of prediction behavior, Furthermore, the behavior of provider bidding game is introduced, and the multi-objective dynamic programming model is constructed on the assumption that the integrator allocates tasks based on the provider's quotation. Through numerical analysis, we compare the changes of task allocation in four different situations (considering the behavior of prediction, considering the game of quotation, considering both the behavior of estimate and the game of quotation, all of which do not take into account). (4) this paper studies the change of task allocation model when the integrator has the ability to provide logistics services. The influence of the quantity and price of the integrator's own service capacity on the task assignment is studied, and some suggestions are put forward for the integrator to manage the logistics service supply chain better. Finally, the conclusion and future prospect are given.
