| Applying queuing theory to optimize inventory control systems, is an important field in the literature of perishable inventory systems. However, a few studies have considered it with (S-1, S) ordering policy and customer satisfaction. In this paper, queuing theory was used to optimize inventory control system and to increase customer satisfaction in a two-stage supply chain of perishable products with exponential life time. The supply chain consists of a manufacturer and a supplier. Customers arrive at the manufacturer according to a Poisson process. Manufacturer uses (S-1, S) ordering policy for stock replenishment. Lead time and processing time are exponentially distributed. The aim is to determine the optimal values of manufacturer’s storage capacity and waiting room capacity. Therefore, the supply chain is modeled as a queuing system. After deriving steady state equations, system performance measures were calculated and a mathematical model was developed to minimize total cost. Optimal solutions were obtained by enumeration and direct search techniques. The sensitivity analysis of the model is performed by a numerical example. | ||
