Keywords: Closed-loop supply chain Environmental impact Social benefit Multi-objective Location model

Costumers and governments are pressuring companies to become more sustainable. However, the lack of research on how to incorporate these issues makes this a challenging task. To fill this gap a generic multi-objective mathematical programming model for the design and planning of supply…

Keywords: Supply chain Closed-loop supply chain Ant colony optimization Nonlinear dimensioning factors

Closed-loop supply chain (CLSC) design implies the modelling of the forward and the reverse flows of products in an integrated way. This paper introduces nonlinear dimensioning factors in the design of CLSC and uses ant colony optimization to optimize the design of the supply chain. The…
