摘要
基于模糊多目标评价 ,对有约束条件的多个投资项目的选择问题 ,建立了一个模糊规划模型 ,利用一种对模糊数排序的解模糊函数 ,对集结成的各项目的非线性模糊综合评价值解模糊 ,将模糊规划模型转化为线性规划模型求解 。
This paper presented a fuzzy programming model for the investment projects selection problem with constrained conditions based on fuzzy multiobjects evaluation. By a defuzzifying function which is used to rank fuzzy numbers to defuzzify the aggregated nonlinear fuzzy contribution indexes of projects, the fuzzy programming model can be converted to a standard linear programming model, and can be solved by the simplex method. An example is provided to illustrate the proposed approach.
