We consider a service facility system with perishable inventory with finite number of servers. Each server having one perishable item for providing service. The arrival of a customer at the system according to independent Poisson Processes with rate  through a single channel. The service time of the customer is exponentially distributed with mean  1/ and the item in stock has exponential life...

This article discusses inventory management of perishable items, including the differences between inventory models that consider items’ perishability and the standard models that ignore this issue. We hope that this article will help fostering the interest of students and researchers in inventory control of perishable items, and ultimately help improving the inventory control of perishable ite...

negative impact of delays on customer service level by keeping redundant inventory or safety stock. Although safety stock protects companies from disruptions or delays, this comes at a cost because higher inventory levels tie up working capital and increase inventory management costs, such as warehousing and damage rates. In addition, the higher inventory level increases the risks associated wi...

One of the important aspects of distribution optimization problems is simultaneously, controlling the inventory while devising the best vehicle routing, which is a famous problem, called inventory-routing problem (IRP). When the lot-sizing decisions are jointed with IRP, the problem will get more complicated called production inventory-routing problem (PIRP). To become closer to the real life p...

perishability of blood products as well as uncertainty in demand amounts complicate the management of blood supply for blood centers. this paper addresses a mixed-integer linear programming model for blood platelets production planning while integrating the processes of blood collection as well as production/testing, inventory control and distribution. whole blood-derived production methods for...

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 ...

A key feature of food products is their perishability. Within the short marketing window that characterizes most food and ag products, demand is typically highly stochastic and difficult to predict. This combination of features poses substantial challenges to retailers when pricing products and has implications for performance that ripples through vertical food chains. For many food products, p...

We study the conditions under which input-output networks can dynamically attain a competitive equilibrium, where markets clear and profits are zero. endow classical firm network model with minimal dynamical rules that reduce supply/demand imbalances excess profits. show time needed to reach equilibrium diverges infinity as system approaches an instability point beyond Hawkins-Simons condition ...
