Comments on "An improved model for vehicle routing problem with time constraint based on genetic algorithm" [Comput. Ind. Eng. 42 (2002) 361-369]
An improved model for vehicle routing problem proposed by Heung-Suk Hwang (2002) was recently published in Computer & Industrial Engineering Journal to solve the time constraint vehicle routing problem based on improved genetic algorithm. In this work, comments are given to the published paper of Heung-Suk Hwang (2002). And they centralize on the example of improved mutation operator and the problem formulation. The suggested modifications are also provided in this work. (C) 2010 Elsevier Ltd. All rights reserved.
