 Role of third-party companies in a sustainable supply chain designMohammad Najjartabar-Bisheh, Mojgan Delavari and Behnam Malmir International Journal of Logistics Systems and Management, 2018, vol. 30, issue 1, 95-112 Abstract: Uncertainties and constraints, such as capacity, add to complexity of supply chain network design, while the role of third-party companies in global supply chain networks is increasing. The present work considered the role of third-party companies in supply chain design in order to increase understanding of the uncertainty of demand, capacity constraints, and backorder shortages. A nonlinear mixed-integer model was introduced to optimise a closed-loop supply chain in an international network. Although exact methods are useful for small size instances, the mixed-integer model was solved by two meta-heuristic algorithms in real-size problems. The ANOVA test was applied for small-sized and large-sized problems in order to check the efficiency of meta-heuristics. Results showed that the imperialist competitive algorithm and particle swarm optimisation gained reliable and efficient solutions. A sensitivity analysis of important inventory parameters such as holding cost and demand was also conducted. Keywords: third-party companies; closed-loop supply chain; meta-heuristic; analysis of variance.
