This problem occurs in production planning in which a decision maker plays a pivotal role in making decisions under a fuzzy environment. Decision maker should be aware of his/her level-of-satisfaction as well as degree of fuzziness while making the product mix decision. Thus, the authors have analyzed using a modified S-curve membership function for the fuzziness patterns and fuzzy sensitivity of the solution found from the multi-objective optimization methodology. An ad hoc Pareto-based multi-objective evolutionary algorithm is proposed to capture multiple nondominated solutions in a single run of the algorithm. Results obtained have been compared with the well-known multi-objective evolutionary algorithm NSGA-II. {\^A}{\copyright} Springer Science + Business Media, LLC 2008.}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-84976463510&doi=10.1007\%2f978-0-387-76813-7\%5f20&partnerID=40&md5=5e56809f2714715625edf5d2fdd156e2}, issn = {19316828}, author = {Jim{\~A}{\copyright}nez, F. and S{\~A}!nchez, G. and Vasant, P. and Verdegay, J.
