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 雖然求這兩類(lèi)模糊線性規(guī)劃的模糊最優(yōu)解的方法并不相同,但其思想具有相似性:首先是把目標(biāo)函數(shù)或約束條件模糊化,給出他們的隸屬函數(shù)的定義;然后給出模糊判決,在此基礎(chǔ)上,規(guī)劃最終都可化為求一個(gè)普通規(guī)劃的解,這個(gè)解可看成模糊線性規(guī)劃的模糊最優(yōu)解。
