ANTS COLONY SYSTEM FOR SUPPLY CHAIN ROUTES OPTIMIZATION

The research work proposes a hybrid simulation based approach for efficiency enhancement of a supply chain operating in Calabria (Italy) in the field of pharmaceutical business retail. The supply chain is made up by several and different actors: suppliers, distribution centers, and pharmacies so the optimal supply chain organization is a critical factor for improving systems efficiency and performances. The attention has been focalized on routes optimization, in other words the supply chain has been analyzed in terms Traveling Salesman Problem (TSP).
