Considering chain to chain competition in forward and reverse logistics of a dynamic and integrated supply chain network design problem

In this paper, a bi-objective model is presented for dynamic and integrated network design of a new entrant competitive closed-loop supply chain. To consider dynamism and integration in the network design problem, multiple long-term periods are regarded during planning horizon, so that each long-term period includes several short-term periods. Furthermore, a chain to chain competition between t...

Design of 7×24 logistics system for hazardous materials (case study: distribution of gasoline)

The transportation of hazardous materials such as gasoline has unique features due to the nature of these type of materials and the importance role of these material in human life. Therefore, determining the routing of these materials is more challengeable than non-hazardous one due to more dangerous and risky condition besides the transportation costs. Since the distribution of gasoline take p...

Reliable multi-product multi-vehicle multi-type link logistics network design: A hybrid heuristic algorithm

This paper considers the reliable multi-product multi-vehicle multi-type link logistics network design problem (RMLNDP) with system disruptions, which is concerned with facilities locating, transshipment links constructing, and also allocating them to the customers in order to satisfy their demand on minimum expected total cost (including locating costs, link constructing costs, and also expect...

Logistics Integrated Product Design under Concurrent Engineering Environment - A Case Study

Logistics, transportation and distribution engineering can be divided into internal or in-plant logistics and external manufacturing or distribution logistics. The Internal or in-plant logistics includes the material handling systems and storage systems and the external manufacturing or distribution logistics includes the transportation modes such as trains and trucks. Both must be integrated i...
