In this paper we consider a periodic review order-up-to-level (or base stock) inventory control system under normally distributed demand. For such circumstances an expression for the exact fill rate (fraction of demand satisfied without backordering) has been available in the literature but has not been widely known, let alone used by practitioners. In this paper we redevelop the expression and...

In economic order quantity models without backordering, both the stock cost of each unit quantity and the order cost of each cycle are characterized as independent fuzzy variables rather than fuzzy numbers as in previous studies. Based on an expected value criterion or a credibility criterion, a fuzzy expected value model and a fuzzy dependent chance programming (DCP) model are constructed. The...

Waste management and reworking are very crucial issues in the cleaner production system. The adaptation of preservation mechanism inventory control is also a key aspect from an economic environmental point view. In current study, model for system modelled considering all these practical inflation. Deterioration process takes place model, market demand viewed sales team efforts selling price dep...

One of the current problems in enterprise management system is creation and replenishment stocks, organization continuous monitoring prompt supply raw materials. Using mathematical models, you can solve problem forming optimal production program enterprise, investing production, as well to carry out strategic planning development.
