Deployment and management of environmental infrastructures, such as charging infrastructure for Electric Vehicles (EV), is a challenging task. For policy makers, it is particularly difficult to estimate the capacity of current deployed public charging infrastructure for a given EV user population. While data analysis of charging data has shown added value for monitoring EV systems, it is not valid to linearly extrapolate charging infrastructure performance when increasing population size.We developed a data-driven agent-based model that can explore future scenarios to identify non-trivial dynamics that may be caused by EV user interaction, such as competition or collaboration, and that may affect performance metrics. We validated the model by comparing EV user activity patterns in time and space.We performed stress tests on the 4 largest cities the Netherlands to explore the capacity of the existing charging network. Our results demonstrate that (i) a non-linear relation exists between system utilization and inconvenience even at the base case; (ii) from 2.5x current population, the occupancy of non-habitual charging increases at the expense of habitual users, leading to an expected decline of occupancy for habitual users; and (iii) from a ratio of 0.6 non-habitual users to habitual users competition effects intensify. For the infrastructure to which the stress test is applied, a ratio of approximately 0.6 may indicate a maximum allowed ratio that balances performance with inconvenience. For policy makers, this implies that when they see diminishing marginal performance of KPIs in their monitoring reports, they should be aware of potential exponential increase of inconvenience for EV users.

In the dynamic environment of increasing regulations, increasing patient demand, decentralization of budgets and enforcement of efficiency, small sized healthcare institutions in the Netherlands are having a difficult time. Although these service providers are usually capable of flexibly delivering healthcare, the investment and overhead for implementing and executing on required quality management standards like ISO 9001 is difficult. In this paper we construct a method for the implementation of an IT-enabled quality management system for small sized healthcare institutions, which is applied through case study. The case organisation provides intra- and extramural care for mentally handicapped persons and young adults with a psychiatric disorder. The quality management system implementation is based on 1) a lightweight IT infrastructure (based at a secure data centre and accessible through remote login) implying secure storage of patients' medical and personal information. Furthermore, the Deming (Deming, 1982) cycle enabled processes and protocols are 2) described in an e-handbook and prototyped via an open source process management system which supports the quality regulation demanded for providing care to patients. The case study supports the validity of our method and the fact that small sized healthcare institutions are able to execute their care while adhering to ISO 9001-like standards, with limited initial costs and relatively low cost of ownership

The main question in this PhD thesis is: How can Business Rules Management be configured and valued in organizations? A BRM problem space framework is proposed, existing of service systems, as a solution to the BRM problems. In total 94 vendor documents and approximately 32 hours of semi-structured interviews were analyzed. This analysis revealed nine individual service systems, in casu elicitation, design, verification, validation, deployment, execution, monitor, audit, and version. In the second part of this dissertation, BRM is positioned in relation to BPM (Business Process Management) by means of a literature study. An extension study was conducted: a qualitative study on a list of business rules formulated by a consulting organization based on the Committee of Sponsoring Organizations of the Treadway Commission risk framework.

Background and aim ʹ Many countries signed the Paris Agreement to mitigate global average temperature rise. In this context, Dutch government decided to realize a reduction of 50% using resources and raw materials in 2030. This paper explores how practice-based research into facility operations can contribute to this aim. Methods / Methodology ʹ Practice-based research which includes direct observations, desk research, and participatory action research. Results ʹ This explorative research presents principles and suggestions for facility managers and procurement managers on how they can embed sustainable materials management in the organisation and how to take control of waste. The proposed suggestions are derived from practice-based research and presented as topics of attention for facility professionals. Originality ʹ Within education of Dutch universities of applied sciences and daily professional facility practices, the phenomenon of materials management is underexposed. To contribute to the national and international climate objectives, (future) facility professionals need better support to reduce waste. Bachelor students were involved throughout this research. This approach gave refreshing insights into waste at the end of the supply chain (control separation units) that can improve informed decisionmaking at the beginning of the supply chain. Practical or social implications ʹ Facility management professionals have an important role to play in the mitigation of global average temperature rise, because of their leading role in procurement, service operations, and materials management. However, they struggle to find sustainable solutions. This paper seeks to inspire professionals with interventions that have proven effectiveness on the reduction of waste. Type of paper ʹ Short research paper.

Greater New Orleans is surrounded by wetlands, the Mississippi River and two lakes. Excess rain can only be drained off with pumping systems or by evaporation due to the bowl-like shape of a large part of the city. As part of the solution to make New Orleans climate adaptive, green infrastructure has been implemented that enable rainfall infiltration and evapotranspiration of stored water after Hurricane Katrina in 2005. The long-term efficiency of infiltrating water under sea level with low permeable soils and high groundwater tables is often questioned. Therefore, research was conducted with the full-scale testing method measuring the infiltration capacity of 15 raingardens and 6 permeable pavements installed in the period 2011–2022. The results show a high variation of empty times for raingardens and swales: 0.7 to 54 m/d. The infiltration capacity decreased after saturation (ca 30% decrease in empty time after refilling storage volume) but all the tested green infrastructure met the guideline to be drained within 48 h. This is in contrast with the permeable pavement: only two of the six tested locations had an infiltration capacity higher than the guideline 10 inch/h (254 mm/h). The results are discussed with multiple stakeholders that participated in ClimateCafe New Orleans. Whether the results are considered unacceptable depends on a number of factors, including its intended purpose, site specific characteristics and most of all stakeholder expectations and perceptions. The designing, planning and scheduling of maintenance requirements for green infrastructure by stormwater managers can be carried out with more confidence so that green infrastructure will continue to perform satisfactorily over the intended design life and can mitigate the effects of heavy rainfall and droughts in the future.

The authors discuss and analyze the complex interplay between rail infrastructure development and land use development of railway station areas in the Netherlands. They argue that although this interrelation has been theorized and studied in the academic literature, the underlying complex and dynamic mechanisms, and the appropriate planning and management responses, are still insufficiently understood. This is particularly relevant for local, regional and national policymakers in the various subsystems, because a lack of network understanding and interconnectedness may produce suboptimal, unsustainable spatial and rail infrastructure planning. In order to better understand and manage the dynamic interrelations between rail infrastructure and urban development in the Delta Metropolis, the serious game SprintCity was developed. The game is played with the real stakeholders (administrators, planners, politicians, interest groups, experts and consultants, etc.). In this paper, the authors describe and analyze why and how the complexity of the real world system was modeled into a serious game.

Presented at Conference: IPMA World Conference 2014, At Rotterdam, The Netherlands, Volume: 28 A taxonomy is used for classifying things in general. For the purpose of this paper it is a systematic classification of competences into hierarchical groups where each sublevel constitutes a breakdown of the higher level. Although a vast amount of research has been done in project management competences, there is no standard set of project management competences used (Nijhuis, 2012). Important reasons for constructing a taxonomy for project management competences are found in comparing previous research and in identifying key fields for project management education in higher education. First a definition of competence is given, secondly the rationale of this research is given by discussing recent research. Several different published taxonomies of competences are reviewed. Finally a proposed taxonomy for project management competences is presented.

From the article: Blockchain technology may have the potential to fundamentally change society and we might currently witness the dawn of a cryptographically secured trust-free transactions economy. One relatively unexplored application domain is waste management. Incorrect waste management practices may lead to illegal pollution or enable fraudulent transactions. Using a design science approach, we formulate problem areas and evaluate the applicableness of using a blockchain solution to mitigate the problems identified. Our results indicate that it is important that the organization and its infrastructure is prepared for the use of blockchain. There are several conditional challenges that must be overcome to realize blockchain technology’s full potential. Further research is needed in order to grasp a full understanding about the situations in which blockchain technology is beneficial or not.

The authors analyze the complex interplay between rail infrastructure development and railway station area development in the Netherlands through the method of gaming-simulation, or serious gaming. The serious game SprintCity was developed in order to better understand and manage the dynamic interrelations between rail infrastructure and urban development of the Delta Metropolis in the Netherlands. So far, the game has been played in nine independent game sessions, with a total of around 70 stakeholders as players. The authors describe the design of the game in some detail and present the preliminary insights and results. Data before, during and after the game sessions are gathered through in-game participant questionnaires, data logging, observations and transcripts of end-of-game (debriefing) discussions between participants and the facilitator. The main conclusion is that the current prototype version of the game is supported by the stakeholder-players, significantly enhances the development and use of the underlying infrastructure-space model and generates questions for further scientific and policy research.
