Analysis of a Decentralized Production-Inventory System

Analysis of a Decentralized Production-Inventory System

We model an isolated portion of a competitive supply chain as a M/M/1 make-tostock queue. The retailer carries finished goods inventory to service a Poisson demand process, and specifies a policy for replenishing his inventory from an upstream supplier. The supplier chooses the service rate, i.e., capacity, of his manufacturing facility, which behaves as a single-server queue with exponential s...

Analysis of a production-inventory system with unreliable production facility

This paper tests the robustness of analytical results on performance measures for a production-inventory system with an unreliable production facility. A basic model is considered which involves a single production machine with constant production rate which operates as long as the accumulated inventory is below a pre-set threshold, and is idle otherwise. The demand process follows a compound P...

Inventory Policies in a Decentralized Assembly System

We consider a system in which a single finished good is assembled from two components. Demand for the finished product is stochastic and stationary, and procurement and assembly leadtimes are constant. Unsatisfied demand is backordered. The inventory of each component or assembly is controlled by a separate firm using a base-stock policy. Each firm is charged holding costs on its own inventory ...

Production Planning and Inventory Control in a Remanufacturing Production System

The management of production and inventory control associated activities in remanufacturing production system has received attention by practitioners in the last two decades. This is due to the increased productivity, limited supply of virgin materials, stringent environmental requirements for product disposal and treatment as well as substatial change in global sustainability regulations. In o...
