The paper addresses the issue of stability for re-entrant flow lines, producing multiple products, with capacitated machines, random demand and random yield. The policies of interest are multi-echelon base stock policies, combined with a set of static and dynamic management rules of the available capacity. We introduce three classes of capacitated echelon base stock policies: Π0, the pure multi...

The municipal solid waste (MSW) disposal system is the key for building smart city. In MSW system, allocated among plants in first echelon, and then derivatives (incineration residues RDF) are between markets second echelon. two-echelon optimal allocation of two objectives, cost environmental impact, should be considered. Considering uncertainty this paper constructs a grey fuzzy multi-objectiv...

To cope with current turbulent market demands, more robust inventory policies are needed for distribution networks, to lower the inventory cost as well as maintain high responsiveness. This paper analyzes the inventory policies in the context of complex multiechelon distribution networks and proposes an optimization and simulation integrating approach to robust inventory policies selection for ...

design of a logistics network in proper way provides a proper platform for efficient and effective supply chain management. this paper studies a multi-period, multi echelon and multi-product integrated forward-reverse logistics network under uncertainty. first, an efficient complex mixed-integer linear programming (milp) model by considering some real-world assumptions is developed for the inte...

This paper proposes a new heuristicmethod for the logistics network design and planning problem based on linear relaxation and DC (difference of convex functions) programming. We consider a multi-period, multi-echelon,multi-commodity andmulti-product problemdefined as a large scalemixed integer linear programming (MILP) model. The method is experimented on data sets of various size. The numeric...

This paper aims at multi-objective optimization of single-product for four-echelon supply chain architecture consisting of suppliers, production plants, distribution centers (DCs) and customer zones (CZs). The key design decisions considered are: the number and location of plants in the system, the flow of raw materials from suppliers to plants, the quantity of products to be shipped from plant...
