In this paper, we consider inventory control problems for deteriorating items with maximum serviceable lifetime under mixed sales situation, both of the demand and deterioration rate are depending on time. A model is presented to formulate process that deteriorated sold consumers together items, where penalty cost products included. From literature search, study one first researches joint inspe...

In this paper, we use market segmentation approach in multiproduct inventory production system with deteriorating items. The objective is to make use of optimal control theory to solve the production inventory problem and develop an optimal production policy that maximize the total profit associated with inventory and production rate in segmented market. First, we consider a single production a...

it is assumed in most of the existing models that the items can be stored for an unlimited time to meet the future’s demand and their quality and quantity does not change during that period. nevertheless there are special kinds of products which deteriorate or become unusable (such as food products, alcohol, medicines, etc.). therefore if the rate of deterioration is significantly high, the imp...

The adaptive production planning of failure-prone manufacturing systems is considered in this paper. In real manufacturing systems, the product demand is usually not known a priori. One of the major tasks in production scheduling is to estimate and predict the demand. In this paper, the authors consider the demand to be either the sum of an unknown rate and a small white noise or the sum of a h...

World electricity production today is heavily dependent on water resources. Studies have shown that global warming and climate changes will have significant impacts on available water resources to produce hydroelectric power. Considering that the reservoir dam in the catchment area of Dez is simultaneously a producer of hydropower and supplier of water needed for agricultural land, the aim of t...
