Zone Selector Delivery Optimisation using Locality in Supply Chain Systems

Supply chain systems and logistics, play a key role in the transportation of goods in the industry. A buyer usually dispatches a request and a seller responds by sending the goods. However, this creates a massive overhead, due to geographic restrictions and cost of the logistics. For this reason companies often create systems that gather supplies in warehouses to support a number of buyers in the area. Thus, the notion of regional collector emerges. The collector essentially manages the sellers in the regions and responds to requests from the buyers. In this paper, we address this problem by creating zones that include sellers to create the zone collector. The zones are created based on a density that creates a community of sellers. The zone collectors, maximise their operations by using locality, in the sense that they collect the supplies from the sellers according to the demand of the buyers. Thus, we propose a solution based on junction tree, in order to increase the global utility function, We provide simulations to show the efficiency of our approach.
