Supply chains are subject to various types of uncertainty. According to Geary et al. (2002), these types of uncertainty can be classified in four categories: demand, process, supply, and control uncertainty. In this presentation, we propose and discuss an integrated hierarchical planning approach for supply chains that generates plans which are robust to two particular types of uncertainty, nam...

In recent years, accidents in food quality & safety frequently occur, and more and more people have begun to think highly of food quality & safety and encourage food producers to be able to trace the origin of ingredients and process of production along the supply chain. With the development of IT, more and more practices have shown that the supply chain of agricultural products should rely on ...

This study considers a combination of cross-docking and vehicle routing problem (VRP) approachesto transport raw material and parts in a supply chain. The supply chain is composed of some supplierswhich are spread in different geographical zones and multiple shared vehicles with different speedsand capacities for transporting orders from the suppliers to a manufacturer.

Electronic business has a strong influence on the relationships between partners within supply chains. Small and Medium Sized Enterprises (SMEs) need an affordable, integrated set of software tools to support integration of their supply chains and to take advantage of the new ways of doing business in the electronic business environment. The paper reviews evolution and current trends in supply ...

This paper investigates how to control an integrated supply chain based on demand-driven principles and sharing of real time information. A set of principles to support a unified supply chain control model is proposed based on theory and previous and ongoing research and illustrated in a case example from the pharmaceutical industry. Essential elements include application of pull-based control ...

In this paper, we consider a pricing decision problem with two competing supply chains which distribute differentiated but competing products in the same market. Each chain can be vertically integrated or decentralized based on the choice of the manufacturer. The manufacturing costs, sales costs and consumer demands are characterized as uncertain variables, whose distributions are estimated by ...

the revenue management concept and techniques are applied to model the coordination of supply chain elements. the fundamental premise of this approach is synchronization of a group of business entities consist-ing of a manufacturer and multiple suppliers to achieve an optimal supply chain capacity plans. the output of the supply chain can be various products and thus it is measured in terms of ...
