Perishable Inventory System with Postponed Demands and Negative Customers
This article considers a continuous review perishable (s,S) inventory system in which the demands arrive according to a Markovian arrival process (MAP). The lifetime of items in the stock and the lead time of reorder are assumed to be independently distributed as exponential. Demands that occur during the stock-out periods either enter a pool which has capacity N(<∞) or are lost. Any demand tha...
متن کاملCompetitive Vehicle Routing Problem with Time Windows and Stochastic Demands
The competitive vehicle routing problem is one of the important issues in transportation area. In this paper a new method for competitive VRP with time windows and stochastic demand is introduced. In the presented method a three time bounds are given and the probability of arrival time between each time bound is assumed to be uniform. The demands of each customer are different in each time wind...
متن کاملVendor Managed Inventory of a Supply Chain under Stochastic Demands
In this research, an integrated inventory problem is formulated for a single-vendor multiple-retailer supply chain that works according to the vendor managed inventory policy. The model is derived based on the economic order quantity in which shortages with penalty costs at the retailers` level is permitted. As predicting customer demand is the most important problem in inventory systems and th...
متن کاملStochastic Discrete-Time Model and Simulation of Inventory Management System
Inventory management plays a very important role in logistics system. This study presents a discrete-time model for regularly order inventory management system considering the randomicity of receiving goods of time and the volume of ordering determined by inventory difference. With the application of Simulink toolbox in MATLAB, an example of block diagram model in z-domain is built to simulate ...
متن کاملOptimum Aggregate Inventory for Scheduling Multi-product Single Machine System with Zero Setup Time
In this paper we adopt the common cycle approach to economic lot scheduling problem and minimize the maximum aggregate inventory. We allow the occurrence of the idle times between any two consecutive products and consider limited capital for investment in inventory. We assume the setup times are negligible. To achieve the optimal investment in inventory we first find the idle times which minimi...
