Comments on “An effective hybrid optimization approach for multi-objective flexible job-shop scheduling problems” [Comput. Ind. Eng. 48 (2005) 409–425

Abstract

An effective hybrid optimization approach proposed by Xia and Wu [Xia, W. J., Wu, Z. M. (2005). An effective hybrid optimization approach for multi-objective flexible job-shop scheduling problems. Computers & Industrial Engineering, 48, 409–425] was recently published in Computers & Industrial Engineering journal to solve the multi-objective flexible job-shop scheduling problems. In this work, comments and suggestions are given to the recently published approach of Xia and Wu (2005). The comments like centralized the problem formulation and experimental comparison. The modification of the problem formulation is suggested in this work.
