Study on the Inventory System with Ordering Quantity Depending on the Suppliers ON Statue
This paper analyzes a continuous-review inventory system with random supply interruptions and stochastic lead-time.A monopolistic supplier alternates between suppliers ON and OFF periods.The variable (r,q)-policy is used q= (q1,q2…,qm).According to the policy,with a constant demand rate,when the inventory level drops to the reorder point r and the supplier is in her statue i,an order with quantity qi(1≤i≤m)$ is placed.If an order placement occurs during a supplier OFF period and the supplier resumes on the statue i,the order with quantity qi is on hold and not processed until the suppliers ON with beginning statue i starts.The order raises the inventory level to a target level qi+ r at the end of the lead-time.Furthermore,the lead-time may be interrupted by the supplier OFF.Using the Continuous Time Markov Chain technology and the renewal theory,a long-run average cost function is obtained.According to this result,the performance evaluation is conducted with example.
