Freight transport network design using particle swarm optimisation in supply chain¬タモtransport supernetwork equilibrium
نویسنده
چکیده
This paper presents a discrete network design problem for optimally designing freight transport network in terms of the efficiency of supply chain. Modelling is undertaken within the framework of mathematical programmes with equilibrium constraints, which first incorporates both supply chain and transport networks explicitly. The upper level determines the best set of actions for transport network improvement, while the lowerlevel decision is based on a supply chain–multimodal transport supernetwork equilibrium. New variants of particle swarm optimisation are developed to approximately solve the upper level. Numerical tests reveal their superior performance and the effective freight transport-related actions. 2015 Elsevier Ltd. All rights reserved.

A Collaborative Stochastic Closed-loop Supply Chain Network Design for Tire Industry
Recent papers in the concept of Supply Chain Network Design (SCND) have seen a rapid development in applying the stochastic models to get closer to real-world applications. Regaring the special characteristics of each product, the stracture of SCND varies. In tire industry, the recycling and remanufacturing of scraped tires lead to design a closed-loop supply chain. This paper proposes a two-st...
متن کاملOn the Relationship Between Supply Chain and Transportation Network Equilibria: A Supernetwork Equivalence with Computations
In this paper, we consider the relationship between supply chain network equilibrium and transportation network equilibrium. We demonstrate that a supply chain network equilibrium model introduced earlier can be reformulated as a transportation network equilibrium model with elastic demands through a supernetwork reformulation of the former. This equivalence allows us to transfer the wealth of ...

متن کاملAccommodating supply chain structure in models of freight mode choice
Modern logistics systems involves complicated interactions amongst many different decision agents within a complex supply chain structures. Accordingly, in contrast to passenger transport, choice decisions in freight transport are typically not concentrated in a single agent, but are co-operatively and sometimes competitively made with different degrees of relationships by multiple individuals ...
