In this multiplayer simulation, each team of students is comprised of a manufacturer, distributor, wholesaler, and retailer. Teams compete against one another to manage their supply chains successfully, minimizing costs over 30 simulated weeks. Students are measured against their counterparts on other teams: the retailers from all teams are scored against each other, the wholesalers from all teams are scored against each other, etc.
Teams must cope with variable demand, lead times, modes of transport, inventory-carrying costs, stock-out costs, and incomplete information across the supply chain. Instructors determine whether or not members of each team are able to share information with each other — regarding inventory on hand, incoming shipments, and demand — so that students may choose to work together to streamline their supply chain. In addition, instructors determine whether information-sharing comes with a cost.
