While there has been considerable work over the years on multistage lot-sizing models, particularly in an MRP environment, there has been relatively little work on systems recognizing the WIP effects when there is gradual conversion of the components into the final product, as in production planning using the EPQ model for planning the final product. Here we consider lot-sizing planning for a t...

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 o...

The main purpose of this paper is to modify Huang’s model [13] by considering two warehouses. In addition, we try to use algebraic method to determine the optimal lot-sizing policy for the retailer under two warehouses and two levels of delay permitted. This paper provides this algebraic approach that could be used easily to introduce the basic inventory theories to younger students who lack th...
