Rationing policies for some inventory systems

A dynamic rationing policy for continuous-review inventory systems

Stock rationing is an inventory policy that allows differential treatment of customer classes without using separate inventories. In this paper, we propose a dynamic rationing policy for continuous review inventory systems, which utilizes the information on the status of the outstanding replenishment orders. For both backordering and lost sales environments, we conduct simulation studies to com...

Myopic Inventory Policies in Continuous Inventory Systems with Emergency Orders

A make-to-order environment requires flexibility in the supply chain to facilitate fast response. Timely supply deliveries can be achieved in a cost-effective manner by having a portfolio of suppliers, or a portfolio of contracts with a single supplier, with different lead times and associated costs. In this paper we address the inventory management of such a system and evaluate the savings ass...

Cost-effective ordering policies for inventory systems with emergency order

Most of the studies on inventory control reported in earlier contributions deal with the optimization problems minimizing an expected cost criterion such as the long-run average cost. However, when the plant engineers design the inventory systems in practical situations, they must take account of reliability into the inventory system as well as economical aspect, where reliability can be define...

Optimality of Zero-Inventory Policies for Unreliable Manufacturing Systems

Coordination Policies for Multi-Echelon Multi- Product Inventory Systems

Starting in the 1960s, a number of academic works have focused in serial and distributed multi-echelon structures and in both deterministic and stochastic environments. Clark and Scarf (1960, 1962) developed a seminal work in which they presented optimal policies for a serial multi-echelon system. Schwartz (1973) studied a deterministic model having one warehouse and N retailers and showed that...
