The Beer Game illustrates the complexities of supply chain management across four stages: Factory, Wholesaler, Distributor, and Retailer. Each stage must carefully manage inventory and place orders with upstream suppliers, facing delays in communication and production. The objective is to minimize total weekly costs, which include inventory costs at $0.50 per keg and backlog costs at $1.00 per keg. The game is played under specific initial conditions, with steady retail demand and considerations for weather and promotions. Players take turns managing each stage simultaneously to optimize performance.
