PARAMETRIC α-LEVEL METHOD OF λ-CONTINUATION FOR FUZZY LINEAR PROGRAMMING PROBLEM
The article considers the well-known method of four fuzzy linear programming problems, which is generalized to the parametric α-level method of λ-continuation. The proposed method makes it possible to reduce the number of cases considered from four to two, and obtain additional solutions on subsets of the square α – λ . The advantage of the proposed approach is that one task in- cludes the previous four tasks as special cases. This method allows us to obtain more general and flexible solutions and to influence the properties of a linear optimization problem: degree of membership, sensitivity, stability. We also give the numerical example of the new method implementation in the pro- gramming support environment MathCAD.
