a new mathematical model for the optimal production isformulated for the inventory management system under time-varyingand stochastic inflation environment for deteriorating items. the timehorizon is finite and demand rate is dependent to the inflation. in thereal situation, some but not all customers will wait for backlogged itemsduring a shortage period, such as for fashionable commodities or...

In many stock disintegration issues of the real world, decay pace certain things might be influenced by other contiguous things. Depending on situation, influence weakened items can reduced eliminating them through examination. We specify a model that impacts average monthly cost, and non-linear programming Lagrangian method is solved specified model. The fuzzify inventory used to determine low...

Supply chain optimization for biomass-based power plants is an important research area due to greater emphasis on renewable power energy sources. This paper develops a robust quantile-based approach for stochastic optimization under uncertainty, which builds upon scenario analysis. We apply our approach to address the problem of analyzing competing biomass supply chains subject to stochastic de...

This paper is concerned with the development of a production inventory model for both ameliorating and deteriorating items. Given an inventory goal level and a production goal rate set by the production facility, and given penalties for the inventory level and for the production rate to deviate from their respective targets, a system total cost objective function is derived. We seek the optimal...

Abstract. In this paper, a production inventory model is developed for the business enterprise which consists of three wings. The first wing is for manufacturing new items, the second wing is for collecting the returned items, while third wing is for remanufacturing the returned item. In this model we consider the fact that the storage item is deteriorated during storage periods and salvage val...

Market segmentation is an essential element of marketing in industrialized countries. Goods can no longer be produced and sold without considering customer needs and recognized the heterogeneity of these needs. In this paper, we use market segmentation approach in single product inventory system with deteriorating items. The objective is to make use of optimal control theory to solve the produc...

Inventory routing problems (IRP) are among important tools to be used for implementing vendor manage inventory. Many researchers try develop methods solving inventory problem, however, only a few developed spoilage items. In reality, many items deteriorated and spoiled during transportation storage period. this paper, we model solve the problem deteriorating with dynamic demand rate, i.e., vari...

In this paper we develop an inventory model, to determine the optimal ordering quantities, for a set of two substitutable deteriorating items. In this inventory model the inventory level of both items depleted due to demands and deterioration and when an item is out of stock, its demands are partially fulfilled by the other item and all unsatisfied demand is lost. Each substituted item incurs a...

In this paper we shall discuss with the optimal ordering policy for two warehouse inventory model of non-instantaneous deteriorating items and stock-dependent demand. Here shortage is not allowed. Here the holding and deteriorating costs in both warehouses are different and assumed that the holding cost in the RW(rented warehouse) than in the OW(owned warehouse) the optimal solution are shown. ...
