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...

The production system is unreliable, therefore, prone to random failures directly affecting the products quality. machine status affected by variation and its use over time. In this work a new maintenance strategy with corrective, imperfect perfect employed when process respectively in control, surveillance, critical stages. We increase reliability of subsequent reduction non-conformal items. S...

Kandpal Deepa H. & Tinani Khimya S. Department of Statistics, Faculty of Science, The M.S. University of Baroda Vadodara-390002, Gujarat, India . ABSTRACT This paper develops a model to determine an optimal ordering policy for deteriorating items under permissible delay of payment and allowable shortage for future supply uncertainty for two suppliers. In this paper we have introduced the aspect...

A supply-chain is a series of connected stock management structures. Therefore, the structure of a supply-chain consists of many cascading inventory management problems. It is known that the optimal inventory control parameter values suggested by the literature are also valid for a supply-chain. The motivation for this study is to investigate the effect of the literature suggested optimal value...

This paper discusses the economic order quantity ( EOQ ) under partial trade credit. In 1985, Goyal assumed that: (i) The unit selling price and the unit purchasing price were equal. (ii) The supplier would offer the retailer full trade credit under condition of delay payments. The main purpose of this paper wants to modify Goyal’s model to presume that the unit selling price and the unit purch...

We analyze an infinite horizon, single product, periodic review model in which pricing and production/inventory decisions are made simultaneously. Demands in different periods are identically distributed random variables that are independent of each other and their distributions depend on the product price. Pricing and ordering decisions are made at the beginning of each period and all shortage...
