The present article elaborates a multi-product economic inventory model in which multiple items are considered with demand, depends on time, abides power law, shortages, and complete backordering. rate of production is greater than the demand for each item. This type pattern accessible to various kinds practical problems modern era. In this paper, assumed be directly proportional demand. real s...

In this paper we study forecast and inventory control problems for DVD-by-mail operations. Specifically, we focus on inventory management for in-circulation items after the new release rental peak. For such items, the demand volume is usually low and unpredictable. Leveraging on the unique operational feature of DVD-by-mail services, we propose effective forecast models for itemlevel returns an...

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 deteriorating items with stock and price dependent demand is developed. Holding cost is considered as function of time. Shortages are not allowed. Numerical examples are provided to illustrate the model and sensitivity analysis is also carried out for parameters.

A continuous production control inventory model for deteriorating items with variable demand rate is developed. Demand rate is the linear function of time. In this paper we have done all work in the environment of permissible delay of payments. A number of structural properties of the inventory system are studied analytically. We have discussed the minimum total system cost under the condition ...

This paper develops a pricing and inventory model of a supply chain composing one supplier and two manufacturers in which the supplier sells its product to two competing manufacturers. Each manufacturer faces a deterministic demand that depends on his/her own and the other competitor sale price. Selling price for the supplier is time dependent and increment function.Both amelioration and deteri...
