One of the most important coordination techniques for software development is to build the effective knowledge network in a software project. The knowledge network, in this paper, refers to interfunctional relationships for obtaining customer needs. We investigated the knowledge networks employing a survey instrument to collect data from a variety of product processes in a Japanese SI (Systems ...

—Since Distributed Generation (DG) often involves renewable energy, it is important to facilitate integration of DG into existing networks. This is the aim of the EU FP6 demonstration project ADINE. It is based on the Active Network Management (ANM) concept, where automation, ICT and power electronics are used to integrate more DG by exploiting active resources instead of just reinforcing the n...

It is expected that the requirements for access networks will change in the future due to the increase in bandwidth demand, due to the shift to packet based services and due to the drive to implement a full service network. Optical access networks are a logical implementation of these requirements. Of all the access infrastructure available, optical fiber has the largest bandwidth potential. In...

Many operations research problems in project management, manufacturing, and elsewhere require the generation of specified sets of activity networks for purposes of testing proposed solution approaches. To date, single-network generators have been used for the resource-constrained project scheduling problem (RCPSP). Since the first single-network generator was proposed in 1993, several advances ...

This study looks at the social network that exists during information systems development (ISD). By introducing a social network perspective of information systems project management, social network analysis and its concepts of embeddedness, structural holes, and centrality can be used to reveal organizational phenomena that might otherwise be overlooked. In this study we analyze the social net...

Knowledge spillovers are a central part of knowledge accumulation. The paper focuses on spillovers that occur through the interaction between different researchers or developers that collaborate in different research projects. The paper distinguishes between project spillovers and contributors' spillovers and between direct and indirect spillovers. The paper constructs a unique data set of open...

Successful open source software (OSS) projects require efficient communication means and a steady supply of voluntary developers. Microblogging, as well as the follower network it generates, is becoming increasingly popular as an emerging Web 2.0 communication technology in many online OSS communities. However, little is known about how microblogging follower networks affect OSS project success...

Projects scheduling by the project portfolio selection, something that has its own complexity and its flexibility, can create different composition of the project portfolio. An integer programming model is formulated for the project portfolio selection and scheduling.Two heuristic algorithms, genetic algorithm (GA) and simulated annealing (SA), are presented to solve the problem. Results of cal...
