A fuzzy multi-objective linear programming approach for solving a new multi-objective job shop scheduling with sequence-dependent setup times

This paper presents a new mathematical model for a hi-objective job shop scheduling problem with sequencedependent setup times that minimizes the weighted meancompletion time and the weighted mean tardiness time. For solving this multi-objective motkl, we develops a fuzzy multiobjectivelinear programming (FMOLP) motkL In this problem, a proposed FMOLP method is applied with respect to the overall acceptable tkgree of the decision maker (DM) satisfaction.Finally, a numerical example demonstrates the feasibility of applying the proposed model to job shop scheduling with set uptimes problem. The proposed model yields a compromised solution and tlte decision maker's overall levels of satisfaction
