This paper presents a first look at long-term delay measurements from data connections in 3 Norwegian 3G Networks. We have performed active measurements for more than 6 months from 90 voting locations used in a trial with electronic voting during this fall’s regional elections. Our monitors are geographically spread across all of Norway, and give an unprecedented view of the performance and sta...

This paper highlights the opportunities and challenges of applying Discrete Event Simulation (DES) to support capacity planning of a network of outpatient facilities. Despite an abundance of studies using simulation techniques to examine the operation and performance of outpatient clinics, the problem of capacity allocation and planning of medical services within a network of outpatient healthc...

This paper considers the time-dependent service network design problem with stochastic demand represented by scenarios. To our knowledge, this is the first attempt to address real life-size instances of this problem. The model integrates the balancing of empty vehicles, the cost of handling freight in intermediate terminals, the costs associated with moving freight using the selected services, ...

Within the field of information systems an interest in environmental issues has driven the agenda for research from green IT improvement to sustainable innovation. A challenge yet to investigate is how sustainable innovation involving a cluster of actors from multiple settings should be 1) designed and 2) orchestrated so that the innovation performed enables sustainable change. Processes for la...

Combining with agricultural production practice, we propose the agriculture wireless and humidity sensor network design, which is based on ZigBee technology. And we use the chip based on the CC2530 ZigBee protocol as the sensor nodes and coordinator nodes for data collection, transmission and display, aiming to realize the agricultural production automation and precision agriculture.

A number of fields, including genome rearrangements and interconnection network design, are concerned with sorting permutations in “as few moves as possible”, using a given set of allowed operations. These often act on just one or two segments of the permutation, e.g. by reversing one segment or exchanging two segments. The cycle graph of the permutation to sort is a fundamental tool in the the...

Choosing the scope of a plan is a fundamental question for plan makers. This question arises both in explaining plan making we observe and in justifying plan making we recommend. We frame this question from the perspective of potential participants, from the bottom up, rather than from the perspective of creating a planning process by expert judgment about scope, from the top down, such as an a...

What is the Internet like, and how do we know? Less tendentiously, how can we make general statements about the Internet without reference to alternatives that help us to understand what the space of network design possibilities might be? This paper presents a series of cases of network alternatives which provide a vantage point from which to reflect upon the ways that the Internet does or does...

Network Design problems concern the selection of arcs in a graph in order to satisfy, at minimum cost, some flow requirements, usually expressed in the form of origin-destination pair demands. Benders decomposition methods, based on the idea of partition and delayed constraint generation, have been successfully applied to many of these problems. This article presents a review of these applicati...
