the traditional economic production quantity (epq) model assumes that during the production process no imperfect item is produced. but in the real production system, due to imperfect production process or other factors, imperfect quality items may be produced. furthermore, it is well-known that the total production-inventory costs can be reduced by reworking the imperfect quality items produced...
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 the recent years, theory of constraints (TOC) has emerged as an effective management philosophy for solving product mix problem with the aim of profit maximization by considering the bottleneck. Furthermore, Fuzzy set theory has been used to model systems that are hard to define precisely and represents an attractive tool to aid research in production management when the dynamics of the pr...
In this model, we establish an inventory model to determine the optimal inventory replenishment scheme for the economic production quantity (EPQ) model for imperfect, deteriorating items with sales return service under multiple production and rework setup. In one cycle, production process can produces the products in m production setups and reworks the defective items in one rework setup. The c...

A multi-item single-period stochastic inventory model is formulated in the fuzzy environment with budgetary, floor-space constraints. In this model, probabilistic demand is related to the unit selling price. Here fuzziness is introduced in both the objective function and constraint goals. The problem is solved using the fuzzy nonlinear technique for linear membership functions. The model is ill...
As competition abounds, the efficient solution on inventory control of a DRP’s (Distribution Requirement Planning) supply chain management is a vital success factor for companies in today’s business world. A stochastic program of market distribution and its deterministic equivalent control program is approximated by a multi-echelon lot-sizing model based on ‘‘risk inflated effective demands”. T...
Manna and Chaudhuri (Eur. J. Oper. Res. 171(2):557–566, 2006) presented a production-inventory system for deteriorating items with demand rate being a linearly ramp type function of time and production rate being proportional to the demand rate. The two models without shortages and with shortages were discussed. Both models were studied assuming that the time point at which the demand is stabil...
