摘要：In this paper, a single item deterministic inventory model with two separate warehouses calledowned warehouse/show-room (OW) and rented warehouse (RW) is developed. The proposedmodel of this paper also considers a realistic assumption regarding the storage capacity of therented warehouse. Demand is a function of selling price, advertisement of an item anddisplayed inventory level in OW. The stocks of RW are shipped to OW under bulk releasepattern where shortages are not allowed. We discuss different scenarios of the proposed modelto address relative size of stock dependency parameters and the capacity of owned warehouse.For each scenario, the corresponding problem is formulated as a constrained mixed integernonlinear programming problem with three integer and two non-integer variables and a realcoded genetic algorithm (RCGA) is developed to solve the resulted problem. The proposedmodel of the paper is also examined using some numerical examples and sensitivity analysis isperformed.
