We consider the problem of minimizing the overall cost of a supply chain, over a possibility long horizon, under demand uncertainly which is known only crudely. Under such circumstances, the method of choice is Robust Optimization, in particular the Affinely Adjustable Robust Counterpart (AARC) method which leads to tractable deterministic optimization problems. The latter is due to a recent re...

today, the effective inventory management plays an important role in the success of the organizations in the new business environment. it is not clearly possible for the organizations that store hundreds of inventory items to economically design an inventory management policy for each inventory item separately. moreover, various inventory items may play quite different roles in the business of ...

In this study, a deteriorating inventory problemwith andwithout backorders is developed. From the literature search, this study is one of the first attempts by researchers to solve a deteriorating inventory problem with a simplified approach. The optimal solutions are compared with the classical methods for solving deteriorating inventory model. The total cost of the simplified model is almost ...

This paper is concerned with the optimal control of a production inventory system with deteriorating items. It is assumed that the deterioration rate follows the two-parameter Weibull distribution. The continuous-review and periodic-review policies are investigated. In each case, optimality conditions are derived. Also, numerical illustrative examples are presented.

A two warehouse production inventory model for deteriorating items is explored in an inflation induced demand and partial backlogging under the effect of learning on set-up cost. Holding cost is treated as a linear function of time and production rate is taken as a linear combination of demand and on-hand inventory. A finite planning horizon inventory problem having two separate warehouses, one...

An inventory problem for a deteriorating item having two separate warehouses is developed under time value of money, whereby one is an own warehouse (OW) of finite dimension(s) and the other is rented warehouse (RW) of infinite dimension(s). Deterioration rate of items in the two warehouses may be different, which is time dependent and deterioration is in the mean beta distribution form. In thi...

This paper investigates a production inventory model under classical EPQ framework with the assumption that customer demand during stock-out period is affected by accumulated back-orders. The backlog rate not fixed; instead, assumed to decrease proportionally existing which thereby approximated piecewise constant function. Deteriorating items are taken into consideration in this work. For bette...
