Integrated inventory models with controllable lead time and backorder discount considerations
Many companies use time as a means of differentiating themselves in the marketplace. In many literatures, the controllable lead time is regarded as a decision variable and decomposed into several components, each having a crashing cost function for the respective reduced lead time. When an item is out of stock, the loyal, patient and captive customers will wait until the outstanding orders arri...
متن کاملFuzzy EPQ inventory models with backorder
Abstract This paper considers the economic production quantity (EPQ) problem with backorder in which the setup cost, the holding cost and the backorder cost are characterized as fuzzy variables, respectively. Following expected value criterion and chance constrained criterion, a fuzzy expected value model (EVM) and a chance constrained programming (CCP) model are constructed. Then fuzzy simulat...
متن کاملPeriodic inventory model with unstable lead-time and setup cost with backorder discount
The main purpose of this study is to investigate the periodic inventory model with backorder price discounts, where shortages are partially backlogged. The application of just-in-time (JIT) philosophy i.e., crashing of the lead-time and setup cost has been carried component wise. Two cases have been discussed viz 1 protection interval demand distribution is known (normal distribution approach) ...
متن کاملContinuous Review and Partial Backorder Inventory System with Controllable Lead Time and Service Level Constraint
Inventory control is important in supply chain management. A great deal of research efforts have been devoted to it over a few decades. Previous researches always assume that the lead time is an exogenously parameter, and the unmet demand is backordered. However, these assumptions may not suit to the real environment. In this paper, a mathematical model regarding inventory control is set up for...
متن کاملThe Variable Lead Time Stochastic Inventory Model with a Fuzzy Backorder Rate
Cost and operation of inventory depends a great deal on what happens to demand when the system is out of stock. In real inventory systems, it is more reasonable to assume that part of the excess demand is backordered and the rest is lost. However, the amount of backorders (or lost sales) often incurs disturbance due to various uncertainties. To incorporate this reality, this article attempts to...
