Raheleh Moazami Goodarzi; Fardin Ahmadizar; Hiwa Farughi

Volume 9, Issue 1 , July 2022, , Pages 63-80


  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
