We study the inventory control problem of a retailer working under stochastic demand and stochastic limited supply. We assume that the unfilled part of the retailer's order is fully backordered at the supplier and replenished with certainty in the following period. As it may not always be optimal for the retailer to replenish the backordered supply, we also consider the setting in which the ret...

We present a two-echelon dual-channel inventory model in which stocks are kept in both a manufacturer warehouse (upper echelon) and a retail store (lower echelon), and the product is available in two supply channels: a traditional retail store and an Internet-enabled direct channel. The system receives stochastic demand from two customer segments: those who prefer the traditional retail store a...

The simultaneous stochastic pricing and inventory management with capacitated cash-on-hand is a profit maximization problem faced by a firm, which has limited working capital for its liabilities. In addition to this working capital constraint, the company has to dynamically price its products and determine inventory levels to minimize its expected cost. In our study, we tackle this complicated ...

Merging companies typically anticipate inventory reductions through pooling of inventory, higher purchasing power or elimination of planning uncertainties in a wider supply chain. In contrasts, companies appear to experience an inventory build-up in the quarters after an acquisition. This is the first attempt that I am aware of to develop an understanding for when, how and why the inventory bui...

Joint managed inventory is an advanced supply chain inventory management tool, which will effectively tackle the complicated problem between the inventory cost of supply chain and service level. The research on inventory model and its’ control under JMI environment is a hot issue at present. In this paper, the authors deeply discuss the question of the inventory time costs about the multi-produ...

background: in any research work the used tools to approach the designed project goals, should be evaluated. the purpose of the present study was to obtain validity and reliability of nutritional knowledge, illness perception and dietary adherence questionnaire. methods: the questionnaire of student ratings of teaching was evaluated in a descriptive study. in this study the views of 11 expert f...

the aim of this study was to develop and obtain the reliability and validity of 8 items short form of spielberger stat-trait anxiety inventory (stai) for use in circumstances where the full form is inappropriate. in this study a correlational method is carried out. using the available sampling, the sample subjects were selected from 161 patients who referred to one of hospitals of isfahan. in t...

this paper presents an inventory model for deteriorating items in which shortages are allowed. it is assumed that the production rate is proportional to the demand rate and greater than demand rate. the inventory model is developed by considering four different circumstances. the optimal of the problem is obtained with the help of mathematica 7 software. numerical examples are given to illustra...
