Abstract The uncertain production-inventory problem with deteriorating items is investigated and an optimal control model developed in the present paper. perturbed by canonical process. Based on uncertainty theory, optimistic-value optimal-based established. study aims to find optimistic value of revenue at a certain confidence level. theory used obtain equation optimality. Using Hamilton–Jacob...

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 value is inco...

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...

a r t i c l e i n f o This paper expands an inventory model for deteriorating items with stock-dependent demand. This model provides time varying backlogging rate as well as time varying deterioration rate. The aim of this model is to determine the optimal cycle length of each product such that the expected total cost (holding, shortage, ordering, deterioration and opportunity cost) is minimize...
