Multi-criteria capital budgeting using FLIP

Abstract

By using fuzzy linear programming (FLIP), tolerance intervals are used for calculating the availability of capital at each point in time. The main advantage, compared to the non-fuzzy problem formulation, is the fact that the decision maker is not forced into a precise formulation for mathematical reasons. Linear membership functions which monotonically increase or decrease in the tolerance interval are used because they can be handled quite easily. A numeric example is given.
