R and D Project Selection Problem with Fuzzy Coefficients

摘要

The multicriteria project selection problem subject to linear constraints, with zero-one decision variables is examined. Linguistic rather than numerical values are used in the project appraisals for each criterion, with their meanings represented by fuzzy sets. The grade of membership of a given alternative, in the fuzzy set of all nondominated alternatives, is computed by an algorithm that converges rapidly on the final solution. Continuity is the only restriction imposed on the membership functions. An example of the overall procedure and topics for future research are presented.
