The main objective when managing inventories in blood supply chains is to establish an efficient balance between the wastage and shortage of units. uncertain demand perishable nature units can result over- or under-stocking increase costs. In this study, we analyze how a proactive transshipment policy avoid future shortages addition mitigate wastage. We consider network hospitals with which eac...

We consider an inventory model for spare parts with two stockpoints, providing repairable parts for a critical component of advanced technical systems. As downtime costs for these systems are huge, ready-for-use spare parts are kept on stock, to be able to quickly respond to a breakdown of a system. We allow for lateral transshipments of parts between the stockpoints upon a demand arrival for a...

A dynamic network consists of a graph with capacities and transit times on its edges. The quickest transshipment problem is defined by a dynamic network with several sources and sinks; each source has a specified supply and each sink has a specified demand. The problem is to send exactly the right amount of flow out of each source and into each sink in the minimum overall time. Variations of th...

This paper investigates the emergence of retail clusters on supply chains comprised of suppliers, retailers, and consumers. An agent-based model is employed to study retail location choice in a market of homogeneous goods and a market of complementary goods. On a circle comprised of discrete locales, retailers play a non-cooperative game by choosing locales to maximize profits which are impacte...

The Tree-of-Hubs Location Problem is studied. This problem, which combines several aspects of some location, network design and routing problems, is inspired by those transportation systems in which (i) several locations send and receive a product, and (ii) the performance can be improved by using transshipment points (hubs) where the product is collected and distributed. We want to locate a fi...

We consider a multi-location inventory system where inventory choices at each location are centrally coordinated through the use of lateral Transshipments. This cooperation between different locations of the same echelon level often leads to cost reduction and service level improvement. However, when some locations face embarrassing storage capacity limits, inventory sharing through transshipme...

Supply chain network is the collection of physical locations, transportation vehicles and supporting systems through which the products and services are managed and ultimately delivered. It connects suppliers, manufacturers, distributors and retailers with competition and collaboration. Each decision maker in the network aims to achieve profit maximization, capacity maximization, and delay mini...

In this paper we present the essential features of an approach for the design of a parallel algorithm for the layout compaction problem. We begin with a formulation of the problem presented by Yoshimura in [4]. This formulation is in terms of the dual transshipment problem. Our approach t o the solution of the dual transshipment problem involves repeated applications of three basic steps, namel...
