Abstract
  In this paper, a new model for hybrid flow shop scheduling is presented in which after the production is completed, each job is held in the warehouse until it is sent by the vehicle. Jobs are charged according to the storage time in the warehouse. Then they are delivered to customers by means of routing ...  Read More

Volume 6, Issue 2 , December 2019, , Pages 120-146

http://dx.doi.org/10.22116/jiems.2019.93028

Abstract
  In this paper, a bi-objective mixed-integer mathematical model is presented for configuration of a dynamic cellular manufacturing system. In this model, dynamic changes and uncertainty in parts demand and machines reliability are considered. The first objective function minimizes total costs and the ...  Read More
