Abstract
Supply Chain Management is a necessary cornerstone for any organization that wants to compete in the current global economy. The need of seriously exploring the concept of global resilient sustainable supply chains within a collaborative perspective is seen as a goal to improve companies’ revenue growth and costumer’s recognition. This project aims to develop novel models to help design and planning global supply chains, to make them more environmental friendly and resilient to disruptions across a long time horizon. IS4 researchers collaborated in the development of an ant colony optimization algorithm for the optimization of closed-loop supply chains.
