Abstract
  This paper deals with optimizing the multi-door cross-docking scheduling problem for incoming and outgoing trucks. Contrary to previous studies, it first considers the simultaneous effects of learning and deteriorating on loading and unloading the jobs. A mixed-integer linear programming (MILP) model ...  Read More

Volume 7, Issue 2 , Summer and Autumn 2020, , Pages 139-164

http://dx.doi.org/10.22116/jiems.2020.195853.1293

Abstract
  This paper introduces a two stage stochastic programming to address strategic hub location decisions and tactical flight routes decisions for various customer classes considering uncertainty in demands. We considered the airline network with the arc capacitated single hub location problem based on complete–star ...  Read More

4. Solving the Vehicle Routing Problem with Simultaneous Pickup and Delivery by an Effective Ant Colony Optimization

M. Sayyah; H. Larki; M. Yousefikhoshbakht

Volume 3, Issue 1 , Winter and Spring 2016, , Pages 15-38

Abstract
  One of the most important extensions of the capacitated vehicle routing problem (CVRP) is the vehicle routing problem with simultaneous pickup and delivery (VRPSPD) where customers require simultaneous delivery and pick-up service. In this paper, we propose an effective ant colony optimization (EACO) ...  Read More
