“…Many of the recently published articles have considered the (Q, R) policy (Sarkara et al, 2015). The advanced inventory management systems and the reduced cost of radio frequency identification technology have made the continuous review inventory control policy (Q, R) a very attractive approach.…”

This study examines the inventory policy for the emerging dual-channel warehouse, which has a unique structure where the warehouse is divided into two areas: one for fulfilling online orders and the other for storing products and fulfilling offline orders. A multi-item inventory model was developed considering the warehouse capacity constraint, demand, and lead time uncertainty.Solution methods are provided for both uniform and normal distributions. Adopting the proposed inventory policy for a dual warehouse is cost effective and adds flexibility to the warehouse and supply chain. The study also offers managerial insights on some critical issues faced by companies operating in a dual-channel context.

In this paper, a two warehouses inventory model with stock-dependent demand has been studied. In case there is limited capacity of the owned warehouse (OW), another warehouse is used named rented warehouse (RW) for large ordered quantity. The deterioration rate of inventory items is different in both the warehouses. In the case of OW, we allow for shortages and consider the time dependent backlogging rate. To achieve the optimal ordered quantity and the optimal interval for the total inventory cost, a solution procedure is established and it concludes the developed model with further extended environments.

“…They used the logarithmic investment function for setup cost reduction and quality improvement by assuming a variable backorder rate. Recently, Sarkar et al (2015) discussed about two models, first model with normally distributed lead time demand and the second model without any specific distribution with known mean and standard deviation. They minimized the total expected cost with order quantity, reorder point, backorder price discount, process quality, and lead time as decision variables.…”

For the past four decades the integrated vendor and buyer supply chain inventory model has been an interesting topic, but quality improvement of defective items in the integrated inventory model with backorder price discount involving controllable lead time has been rarely discussed. The aim of this paper is to minimize the total related cost in the continuous review model by considering the order quantity, reorder point, lead time, process quality, backorder price discount and number of shipment as decision variables. Moreover, we assume that an investment function is used to improve the process quality. The lead time demand follows a normal distribution. In addition, the buyer offers backorder price discount to motivate the customers for possible backorders. There are some defective items in the arrival lot, so its treatment is also taken in account in this paper. We develop an iterative procedure for finding the optimal values of decision variables and numerical example is presented to illustrate the solution procedure. Additionally, sensitivity analysis with respect to major parameters is also carried out.
