In the agricultural cooperation coalition,due to the influence of information asymmetry,environmental un-certainty and market volatility,its utility function is often difficult to be expressed by precise numbers,while trape-zoidal fuzzy numbers can well express the above fuzzy uncertainty.Under the basic framework of fuzzy cooperative game theory,an optimization model is constructed to minimize the variance of the quadratic excess of the coalition,and its analytical formula is obtained.Based on this,a trapezoidal fuzzy number least squares prenucleolus is created,and the important properties of the prenucleolus are discussed.Through a real example of profit distribution of agri-cultural cooperative coalition,the rationality and feasibility of the fuzzy cooperative game solution proposed in this pa-per in solving the profit distribution problem of agricultural cooperative coalition are verified.
