Janssen, M. (author), Lee, J. (author), Bharosa, N. (author), Cresswell, A. (author)Multi-agency disaster management requires collaboration among geographically distributed public and private organizations to enable a rapid and effective response to an unexpected event. Many disaster management systems often lack the capability to cope with the complexity and uncertainty. In this introduction to the special issues on advances...journal article 2009

Bharosa, N. (author), Lee, J. (author), Janssen, M. (author)Although various scholars have researched issues regarding disaster management, few have studied the sharing and coordinating of information during disasters. Not much empirical data is available in this field and there is sparse insight into the factors that may impede or facilitate information sharing and coordination among stakeholders. In...journal article 2009

Gonzalez, R.A. (author)This paper presents a crisis response simulation model architecture combining a discrete-event simulation (DES) environment for a crisis scenario with an agent-based model of the response organization. In multi-agent systems (MAS) as a computational organization, agents are modeled and implemented separately from the environmental model. We...conference paper 2009

De Wit, A.J. (author)Complex systems, such as those encountered in aerospace engineering, can typically be considered as a hierarchy of individual coupled elements. This hierarchy is reflected in the analysis techniques that are used to analyze the physcial characteristics of the system. Consequently, a hierarchy of coupled models is to be used, accounting for...doctoral thesis 2009

De Rooij, J.P.G. (author)The aim of this dissertation was to study the little examined, yet important issue of leadership for distributed teams. Distributed teams are defined as: “teams of which members are geographically distributed and are therefore working predominantly via mediated communication means on an interdependent task and in realizing a joint goal” (adapted...doctoral thesis 2009

Yuan, Y. (author), Daamen, W. (author), Hoogendoorn, S. (author), Vrancken, D. (author)The steadily increasing numbers and lengths of traffic jams on freeways have led to the application of Dynamic Traffic Management (DTM) measures all over the world. Ramp metering control has proven to be one of the most efficient means to reduce freeway congestion. Currently, it is expected that integrated and coordinated application of DTM...conference paper 2010

He, H. (author)Physical particle packing is becoming a hot topic in concrete technology as more and more types of granular materials are used in concrete either for ecological or for engineering purposes. Although various analytical methods have been developed for optimum mixture design, comprehensive information on particle packing properties is still missing...doctoral thesis 2010

De Wit, A.J. (author), Van Keulen, A. (author)Multi-level optimization and multi-disciplinary optimization are areas of research that are concerned with developing efficient analysis and optimization techniques for complex systems that are made up of coupled elements (components). Within the field of multilevel optimization and multi-disciplinary optimization a large number of techniques...conference paper 2010

Gonzalez, R.A. (author)Crisis response efforts often require coordinating a previously unknown adhocracy of agencies under time pressure. While current technologies that support coordination are successful for well-defined static process descriptions, they may fall short in the face of more complex and unpredictable scenarios, such as a crisis or emergency. Using...doctoral thesis 2010

Frijlink, M. (author), Wapenaar, C.P.A. (author)One-way wave equations conveniently describe wave propagation in media with discontinuous and/or rapid variations in one direction, but with smooth and slow variations in the complementary transverse directions. In the past, reciprocity theorems have been developed in terms of one-way wave fields. The boundaries of the integration volumes and...journal article 2010

Bayerl, P.S. (author), Lauche, K. (author)For highly interdependent yet location-specific tasks, distributed teams need to closely coordinate activities and processes. This field study in the upstream oil and gas industry focused on challenges in the coordination of highly interdependent tasks if teams work remotely on an ongoing basis. Based on 78 semi-structured interviews and...journal article 2010

Bayerl, P.S. (author)The goal of this project was two-fold: firstly, to add to the theoretical knowledge about the impact of complex media combinations for distributed team coordination, and secondly, to increase the practical knowledge for organizations and designers on how to design and implement complex technological solutions for the support of distributed teams...doctoral thesis 2010

Corman, F. (author), D'Ariano, A. (author), Pacciarelli, D. (author), Pranzo, M. (author)Railway dispatchers are in charge of rescheduling trains during operations in order to limit propagation of disturbances occurring in real-time. To help the dispatchers in such task, an advanced decision support system, ROMA (Railway traffic Optimization by Means of Alternative graphs), has been recently implemented to optimize railway traffic...journal article 2010

Bharosa, N. (author)During daily operations, relief agencies such as police, fire brigade and medical services manage information in accordance with their respective processes and organization structure. When disaster strikes, the ad-hoc combinations of such hierarchy based information systems fail to assure high information quality (IQ) and system quality (SQ) for...doctoral thesis 2011

Lin, S. (author)Model Predictive Control is applied to control and coordinate large-scale urban traffic networks. However, due to the large scale or the nonlinear, non-convex nature of the on-line optimization problems solved, the MPC controllers become real-time infeasible in practice, even though the problem is solvable in theory. In this thesis, we mainly...doctoral thesis 2011

Khodabandeh, A. (author), Amiri-Simkooei, A.R. (author), Sharifi, M.A. (author)The efficacy of robust M-estimators is a well-known issue when dealing with observational blunders. When the number of observations is considerably large—long time series for instance—one can take advantage of the asymptotic normality of the M-estimation and compute reasonable estimates for the unknown parameters of interest. A few leading M...journal article 2011

Klievink, B. (author)Governments aim to improve service delivery towards citizens and businesses. One of the main trends in this area is that organisations are increasingly trying to integrate service delivery by using information and communication technology (ICT). Service integration is necessary as individual service offerings are often just a part of a bigger...doctoral thesis 2011

However, the decisions taken in one area may influence the quality and even the feasibility of train schedules in the other...journal article 2011

Noroozian, A. (author), De Weerdt, M.M. (author), Witteveen, C. (author)The fundamental problem with P2P networks is that quality of service depends on altruistic resource sharing by participating peers. Many peers freeride on the generosity of others. Current solutions like sharing ratio enforcement and reputation systems are complex, exploitable, inaccurate or unfair at times. The need to design scalable...conference paper 2012
