DENOVO PROGRAMMING WITH FUZZY COEFFICIENTS AND MULTIPLE FUZZY GOALS

In an earlier paper by the authors (J. Math. Anal, .4ppl.153, 1990, 97-111), the general multiple criteria de novo programming was solved by the use of the fuzzy concept, where the fuzzy goals and fuzzy coefficients were treated separately. This paper presents an improved approach where both the goals and the coefficients are treated simultaneously. Depending on the numerical approach, the resulting problems can be solved either as a linear problem combined with a search routine or as a nonlinear programming problem. © 1993 Academic Press, Inc.
