Sparing, D. (author), Goverde, R.M.P. (author), Hansen, I.A. (author)We present an optimization model which is able to generate feasible periodic timetables for networks given the line structure and the requested line frequencies, taking into account infrastructure constraints and train overtake locations. As the model uses the minimum cycle time as the objective function, the stability of the timetable is also...conference paper 2013

Hansen, I.A. (author), Wiggenraad, P.B.L. (author), Wolff, J.W. (author)Benchmark analysis of railway networks and companies has been stimulated by the European policy of deregulation of transport markets, the opening of national railway networks and markets to new entrants and separation of infrastructure and train operation. Recent international railway benchmarking studies which are mostly based on statistical...conference paper 2013

(author), Hansen, S. (author), Svendsen, S. (author), Stenlund, O. (author), Paiho, S. (author)In theory, there is huge potential for reducing the energy consumed by existing single-family houses by thoroughly renovating them. For the successful market development of highly energy-efficient integrated renovations, supply chain collaboration is very important, while at the same time customer demand for integrated renovations has to be...journal article 2012

Straub, A. (author), Prins, M. (author), Hansen, R. (author)Integrated building contracts are assumed to result in lower costs, better performance and more innovative solutions as a result of a collaborative environment, output specifications and long-time commitment. Life cycle costs can be reduced when investment and exploitation costs are brought in line with one another. The Dutch government gave...journal article 2012

Koenders, E.A.B. (author), Ukrainczyk, N. (author), Hansen, W. (author)Latest developments in Hymostruc enable the possibility to evaluate the pore connectivity of an evolving microstructure while also considering the contribution of the ITZ and air voids and to examine the influence on frost durability. The numerical model is used to visualize this phenomenon and to show the contribution of both the pores and the...conference paper 2012

Borgnakke, C. (author), Hansen, W. (author), Kang, Y. (author), Liu, Z. (author), Koenders, E.A.B. (author)Freezing of water can be explained by the thermodynamic properties of the water due to the influence of temperature, pressure and special effects such as surface tension and salt solution. Gibbs free energy curves for ice and pore liquid containing different concentrations of NaCl (0-6%) are presented. These curves explain the onset of freezing...conference paper 2012

(author)Within an ERANET-ERACOBUILD project, this study investigates the opportunities and barriers to establish a “one stop shop” with an integrated supply side, to counteract the fragmented offer in sustainable renovation of single-family houses and to increase the level of knowledge, skills and innovations. Aspects of providing reliable information...conference paper 2012

Kecman, P. (author), Goverde, R.M.P. (author), Hansen, L.D. (author)Data records from tram describer systems represent a valuable source of information for analysing system performance and assessing railway timetable quality. The aim of this paper is to introduce the Dutch tram describer system and present algorithms developed for automatic identification of track blockages, route conflicts (including the...conference paper 2011

Wang, Z.B. (author), Vroom, J. (author), van Prooijen, B.C. (author), Labeur, R.J. (author), Stive, M.J.F. (author), Hansen, M.H.P. (author)The Wadden Sea consists of a series of tidal lagoons which are connected to the North Sea by tidal inlets. Boundaries to each lagoon are the mainland coast, the barrier islands on both sides of the tidal inlet, and the tidal watersheds behind the two barrier islands. Behind each Wadden Island there is a tidal watershed separating two adjacent...conference paper 2011

Hansen, R. (author), Prins, M. (author), Straub, A. (author)In most literature integrated contracting and procurement is assumed to result in more innovative solutions as a result of the intended process integration. This paper explores Design Build Finance Maintain Operate (DBFMO) cases in the Netherlands on resulting innovations focusing on maintenance and energy-use. It is assumed that in DBFMO...conference paper 2011

Corman, F. (author), D'Ariano, A. (author), Pranzo, M. (author), Hansen, I.A. (author)Railway traffic experiences disturbances during operations while dispatchers need actions to restore feasibility and limit spreading of delays through the network. To help the dispatcher in such task, the dispatching support tool ROMA (Railway traffic Optimization by Means of Alternative graphs) has been designed and implemented. We report on...conference paper 2010

Hansen, I.A. (author)The paper discusses the current state of research concerning railway network timetabling and traffic management. Timetable effectiveness is governed by frequency, regularity, accurate running, recovery and layover times, as well as minimal headway, buffer times and waiting times. Analytic (queuing) models and stochastic micro-simulation are...conference paper 2009
