Abstract

reservation of a product is an important issue in the inventory control system. It pre�vents the deterioration effect of the products while these are stored in the warehouse/showroom. Considering deterioration effect of the product and preservation technology, an inventory model of non-instantaneous deteriorating items is developed with the demand dependent on the selling price of the product. Two different preservation rates are considered. Shortages are allowed par�tially with two different backlogging rates. Due to consideration of three-parameter Weibull dis�tributed deterioration and preservation facility, the corresponding optimization problems are highly nonlinear. So, these problems cannot be solved analytically due to nonlinearity. To overcome this situation, different variants of quantum-behaved particle swarm optimization (QPSO) are used. To illustrate and validate the proposed model, a numerical example is considered and solved for each case, and compared the results with the different variants of QPSO algorithms. Finally, a sen�sitivity analysis is performed to study the effect of changes of different parameters of the model on the optimal policy.
