| With the vigorous development of urban economy,the scale of urban distribution market is expanding constantly.At the same time,urban distribution enterprises have serious homogeneous competition,low efficiency of resource utilization,poor service quality,high cost and other problems emerge in an endless stream.Urban distribution enterprises cooperate to establish joint distribution coalitions and implement largescale and intensive operations,which can make full use of logistics resources and help enterprises achieve cost reduction,quality improvement and efficiency increase.The key to ensure the long-term stable and healthy development of joint distribution coalition is to establish a fair and reasonable profit allocation mechanism.From the perspective of cooperative game,this paper describes the overall dissatisfaction of the coalition by using the coalition benefit excess and coalition contribution excess,and uses the least square method to establish a model,seeking the profit allocation strategy to minimize the overall dissatisfaction of the coalition,and carries out analysis and verification through the case.Firstly,the paper discusses the characteristics and problems of urban distribution industry,and analyzes the motivation and significance of the formation of joint distribution coalition.At the same time,it introduces the cooperative game and least square method,which can be used to solve the profit allocation problem of joint distribution coalition.Secondly,the coalition benefit excess and coalition contribution excess are used respectively to describe the overall dissatisfaction of the coalition,and the influence of coalition weight is taken into account,and the corresponding profit allocation model is constructed to solve the problem.It is proved that the obtained solutions have good properties such as uniqueness,effectiveness and symmetry.Thirdly,coalition benefit excess and coalition contribution excess are used to describe the overall dissatisfaction of the coalition,and the influence of coalition weight,coalition benefit and contribution importance is considered.On this basis,the corresponding cooperative game solutions are obtained and proved to have many good properties.Finally,it simulates the situation of joint distribution coalition among three urban distribution enterprises.Through the income accounting of urban distribution enterprises,the operation of the joint distribution coalition is analyzed,the benefits and contributions of the coalition are quantified,and the profits obtained by the joint distribution coalition are distributed accordingly,so as to verify the rationality and practicability of the profit allocation strategy proposed in this paper.Based on the cooperative game theory,this paper studies the profit allocation strategy considering coalition benefit,coalition contribution,coalition weight,coalition benefit and contribution importance degree,which is an in-depth study and powerful expansion of the least square prenucleolus solution,and provides the decision basis and theoretical support for the establishment of the profit allocation mechanism of joint distribution coalition. |
