In spite of different methods to a fuzzy optimal solution to the two classes of fuzzy linear programming, these methods have similar ideas : first is to fuzzify the objective function and constraints, i . e ., to display the definition of fuzzy membership function . second is to transfer the fuzzy linear programming into one general linear programming, based on the fuzzy decision, then we can obtain the fuzzy optimal solution by solving this linear programming 虽然求这两类模糊线性规划的模糊最优解的方法并不相同,但其思想具有相似性:首先是把目标函数或约束条件模糊化,给出他们的隶属函数的定义;然后给出模糊判决,在此基础上,规划最终都可化为求一个普通规划的解,这个解可看成模糊线性规划的模糊最优解。
