It is being increasingly acknowledged, in both the IS and sustainability literature that the greatest opportunity for “green” information systems is in the reduction of energy consumption and associated green house gases through the optimal design of supply and demand networks. This paper reports the findings of a multiple case study investigation into how a comparatively new green IS framework...

This paper proposes a tractable model for the design of a rapid transit system. Travel cost is minimized and traffic capture is maximized. The problem is modeled on an undirected graph and cast as an integer linear program. The idea is to build segments within broad corridors to connect some vertex sets. These segments can then be assembled into lines, at a later stage. The model is solved by b...

Techno-economical studies in telecommunication networks are important and quite complicated topics. One of the major challenges is to estimate the investment in new or additional network equipment to consider a new service, or to compare two technologies in the same or different frequency band. In order to carry out this kind of analysis, a nationwide network design and dimensioning study has t...

Network design models are extensively used to represent a wide range of planning and operation management issues in transportation, telecommunications, logistics and production-distribution. In a very general sense, the problem consists of designing a network by selecting links to connect a set of nodes and to determine the amount of flow on each link such that the demand of each node for a num...

M production to low-wage countries may reduce manufacturing costs, but it increases logistics costs and is subject to foreign trade barriers, among others. This paper studies a manufacturer’s multimarket facility network design problem and investigates the offshoring decision from a network capacity investment perspective. We analyze a firm that manufactures two products to serve two geographic...

In this paper the design of the service network in intermodal barge transport is studied. The network of inland barge terminals is modeled to demonstrate potential cooperations in a corridor network. Cooperation between inland terminals leads to bundling of freight flows in the hinterland of major ports. A service network design methodology for intermodal barge transport is developed and applie...

The research project entitled Design and Management of Global Supply Chains (GLOBOP) focuses on the specific model configuration stages with productive multi location and new productive implantations, which affect the design of productive and logistic systems, and the associated supplier network design. This research project aims to offer a methodological and technical solution for those compan...

Reverse logistics, as defined by the European Working Group on Reverse Logistics, is the process of planning, implementing and controlling backward flows of raw materials, in process inventory, packaging and finished goods, from a manufacturing, distribution or use point, to a point of recovery or point of proper disposal. In the broadest sense, this process involves collection, inspection, rec...

The model-based approach to fault detection and isolation in automated process has received considerable attention during the last two decades. One of the approaches to facilitate fault isolation is to design a structured residual set. The term structured here means that each residual is designed to be sensitive to a certain group of faults and insensitive to others. However, despite this issue...
