INVESTIGATING THE SUSTAINABILITY OF PRODUCT SUPPLY CHAINS

According to the growing pressure on Sustainability issues from governances, manufacturing industries must pay their attention to optimize their processes. Anyway, it is necessary go behind this preliminary approach, extending the boundaries from the single company to the other actors that operate in the same supply chain. In this context, the paper proposes a methodology to increase the sustainability and to guarantee the traceability along the whole product supply chain. The methodology allows to model any supply chain, through the data collection from all the actors involved, and to measure the environmental sustainability, through the implementation of a distributed software system. The experimental case study, which involved a leather shoe supply chain, allowed to demonstrate the effectiveness of the approach in the selection of suppliers and in the optimization of the supply chain, taking into account the environmental aspects together with the other constraints such as design, costs and quality.
