A Fuzzy Goal Programming Approach for a Single Machine Scheduling Problem
Abstract
This paper presents the fuzzy mixed-integer goal programming model for a single machine scheduling problem with bi-objectives consisting of the minimization of the total weighted flow time and total weighted tardiness. This model is solved by a fuzzy goal programming approach to verify and validate the proposed approach for the above problem. Two test problems in small and large sizes are generated at random and then the computational results demonstrate the effectiveness of the proposed approach.
