Analyzing the make-to-stock queue in the supply chain and eBusiness settings

This thesis presents two applications of the prototypical make-to-stock queue model that are mainly motivated by supply chain management and e-commerce issues. In the first part, we consider the decentralized version of the make-to-stock model. Two different agents that we call the supplier and the retailer control production and finish goods inventory level independently. The retailer carries finished goods inventory to service an exogenous demand and specifies a policy for replenishing his/her inventory from the upstream supplier. The supplier, on the other hand, chooses the capacity of his manufacturing facility. Demand is backlogged and both agents share the backorder cost. In addition, a linear inventory holding cost is charged to the retailer, and a linear cost for building production capacity is incurred by the supplier. The inventory level, demand rate and cost parameters are common knowledge to both agents. Under the continuous state approximation that the M/M/1 queue has an exponential rather than geometric steady-state distribution, we characterize the optimal centralized and Nash solutions, and show that a contract with linear transfer payments based on backorder, inventory and capacity levels coordinates the system in the absence of participation constraints.
