An EPQ Model for Product Life Cycle (Maturity Stage) with Deteriorating Items and Shortages
A product life cycle is the life span of a product in which the period begins with the initial product specification and ends with the withdrawal from the market of both the product and its support. A product life cycle can be divided into several stages characterized by the revenue generated by the product. This study investigates inventory control policies in a manufacturing system for a si...
متن کاملOptimal pricing and replenishment policies for instantaneous deteriorating items with backlogging and trade credit under inflation
In this paper we develop an economic order quantity model to investigate the optimal replenishment policies for instantaneous deteriorating items under inflation and trade credit. Demand rate is a linear function of selling price and decreases negative exponentially with time over a finite planning horizon. Shortages are allowed and partially backlogged. Under these conditions, we model the ret...
متن کاملCredit financing in economic ordering policies for defective items with allowable shortages
In the classical inventory models, the common unrealistic assumption is that all the items produced are of good quality in nature. However, in realistic environment, it can be observed that there may be some defective items in an ordered lot. These items are usually picked up during the screening process and are sold as a single lot at the end of screening process. Further, it is tacitly assume...
متن کاملA Note on the Criteria of Optimal Solution for Replenishment Policy for Ameliorating Item with Shortages
Ameliorating products are frequently seen in stock management. Considering ramp type pattern of time dependent demand for such products is a justification for the development of related inventory theory. In a recently published paper by Singh et al. (2011), such kind of problem is discussed. However, the solution given by author is incomplete because that fails to depict the case for optimal re...
