| Abstract: | 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. |
