Advertisement of the product is an important factor in inventory analysis. Also, price and stock have an important role to attract more customers in the competitive business situations. Trade credit policy is another important role in inventory analysis. We have combined these three factors together in a two-warehouse inventory model and represented it mathematically. In addition, we have added...

The paper investigates a two-echelon production-delivery supply chain model for products with stochastic demand and backorder-lost sales mixture under trade-credit financing. manufacturer delivers the retailer’s order quantity in number of equal-sized shipments. replenishment lead-time is such that it can be crashed to minimum duration at an additional cost treated as investment. Shortages inve...

In this paper, we consider an integrated vendor-buyer inventory policy for a continuous review model with a random number of defective items and screening process gradually at a fixed screening rate in buyer’s arriving order lot. We assume that shortages are allowed and partially backlogged on the buyer’s side, and that the lead time demand distribution is unknown, except its first two moments....

The main purpose of this study is to investigate the periodic inventory model with backorder price discounts, where shortages are partially backlogged. The application of just-in-time (JIT) philosophy i.e., crashing of the lead-time and setup cost has been carried component wise. Two cases have been discussed viz 1 protection interval demand distribution is known (normal distribution approach) ...

-In this paper, we introduce a new mixed priority scheme that utilizes the logarithmically equi-spaced random transmitter power levels (LESRTPL) model to control the assignment of the transmitter power levels, assigned to each priority class, adaptively. Packets, of different priority classes contending simultaneously over the wireless channels to capture a contention slot, will transmit using ...

Most periodic review models in the inventory literature have assumed a fixed length of the review periods. In this note, we extend the work of Chiang (2008) , and consider backlogged and lost-sales periodic review models where the review periods are of a variable length and there is a fixed cost of ordering for replenishment. Assuming that period lengths are independently and identically distri...

The current IEEE 802.16a and 802.16d standards of wireless metropolitan area networks specify a ranging channel in the OFDMA physical layer that employs a set of CDMA codes for ranging and bandwidth requests. The ranging channel is contention-based and inherently unstable. In this paper, we propose two stabilization algorithms to enable efficient utilization of the ranging channel at close to t...

We develop a two-warehouse production model with imperfect items. Production rate is taken as the linear combination of on-hand inventory and demand, while demand rate is taken as function of time. Most of the researchers consider that the production rate is independent from the demand rate. In this paper we assume production rate as being dependent on the demand rate, and this assumption is mo...
