Abstract
ABSTRACT Considering the main pillars of sustainable development, this paper proposes a new multi-objective model to design a sustainable closed-loop location routing supply chain network taking the pharmaceutical products life cycle as a case study. This model aims at generating economic gains, increasing the social responsibility of companies in terms of job creation and reducing the risk arising from the transport of end of Life products (medical waste from the expiry of pharmaceutical products and their use in the healthcare centres). The multi-objective model expressed as mixed integer linear program was solved by an exact approach, this resolution allowed us to take strategic and operational decisions. Besides, the tuning of objective’s weight helps us to analyse the trade-off possibility between the different objectives and to highlight the impact of social responsibility on the design of closed-loop routing supply chain networks.
