Abstract:Considering that the traditional profit allocation method cannot allocate the profit of the dynamic alliance with limited communication structure commendably, and has strong subjectivity of index weight assignment, a more reasonable and effective profit distribution method is put forward by using graph theory and cloud theory. First, based on the traditional average tree solution, profit impact factors such as risk allocation, cooperative efforts and resources investment are introduced. And using the basic idea of TOPSIS method, the cloud gravity centroid judgement is improved. Then based on ideal and negative ideal state, the correction coefficient of the income distribution is determined, which makes up the traditional profit allocation method. Finally, the new method is applied to the example of dynamic alliance profit allocation. It is found that the profit distribution of the method is better than that of the independent operation, and the rationality and feasibility of the method is verified.
