Determine the Optimal Order Quantities in Lot Sizing Models Regarding Minimum Order Quantity with Simulation

Lot sizing Minimum order quantity Shortage Simulation In this study, lot sizing models of offer so that the cost shortage, holding inventory of exposure, ordering are to be considered and try to determine the values of Qm or maximum inventory so that the total cost could be as little as possible. Lot sizing systems with the specified consumption in a general model are studied and optimization of component variables into a comprehensive model is presented. The process of ordering for a single product and for a single machine is considered. Faced with a shortage is allowed by back log .This study try to follow the optimal policy that specified at the beginning of which period and how much to stock, so that minimize the total costs, which consists of the ordering costs, holding costs and shortage cost. To achieve optimal responses to the decision variables and objective function of the lot size system simulation software is used Arena. Finally, numerical examples and its sensitivity analysis of key parameters are given to illustrate the proposed model.
