An inventory model for Weibull deteriorating items with time varying demand under permissible delay in payments and inflation is considered. Holding cost is linear function of time. Shortages are permitted and are completely backlogged. Sensitivity with respect to parameters has been carried out. Numerical example is taken to support the model.

An inventory model for two warehouses with different deterioration rates is developed. Demand is considered as linear function of time. Holding cost is time dependent. Shortages are allowed and completely backlogged. To support the model numerical case is given. Affectability investigation is likewise done for parameters.

We study a continuous review inventory model over a nite-planning horizon with deterministic varying demand and constant deterioration rate. The model allows for shortages, which are partially backlogged at a rate which varies exponentially with time. For this model an optimal replenishment policy is established. c © 2000 Elsevier Science B.V. All rights reserved.

Proportional Fair (PF), a frequently used scheduling algorithm in 3G wireless networks, can unnecessarily starve “well-behaved” users in practice. One of the main causes behind PF-induced starvation is its inability to distinguish between users who are backlogged and users who are not. In this paper, we describe how a simple parallel PF instance can mitigate such starvation.

In this paper, we discuss the production inventory model with timevarying production, time dependent demand and non-linear shortage cost under inflation and time discounting. Shortages are allowed and are partially backlogged. Here, total cost and time durations are the decision variables. Numerical Examples are given to illustrate the model.

An inventory model for deteriorating items with stock and price dependent demand is developed. Holding cost is considered as function of time. Shortages are allowed and completely backlogged. Numerical example is provided to illustrate the model and sensitivity analysis is also carried out for parameters.

in today’s business transactions, it is frequently observed that a customer is allowed some grace period (permissible delay in payment) before settling the account with the supplier or producer. this policy is advantageous both for the supplier and customer since supplier attracts more customers and customer does not have to pay any interest during this fixed period either. in this paper, the r...

In this paper, an inventory model for multiple products with stochastic demands is developed. The scheduling period or cycle known and prescribed. Demands are independent random variables they follow power patterns throughout the cycle. For each product, aggregate demand realized first then released to system gradually according within a These express different ways of drawing units from can be...
