Modularity theory makes a compelling argument: modular product design increases the potential number of persons that could work on a distributed project and has a positive effect on their labour productivity because it allows them to work independently of each other, with little or no need for central coordination. This doctoral dissertation sets out to put this argument to the test by studying a phenomenon that combines both scale and modularity: Free and open source software (FOSS) development. Its central question is: Does modularity mitigate the adverse effects of increasing scale in FOSS development?

To ensure dependable, affordable, and sustainable use of energy, stakeholders in energy production, distribution, and consumption are increasingly seeking for cooperation. They aim to jointly tackle large energy projects in an environmental context that is changing at an increasing rate, towards increasing complexity. Cooperation is seen as a remedy against the uncertainties of a hyper-competitive society, but the mechanisms of cooperation and the trade-offs are still poorly understood. This thesis provides clarification on how we can use different methods to understand cooperation activities and how to support cooperative efforts.more
The degree of supply chain risk faced by many companies has risen dramatically and the impact of disruptions can cascade easily across companies’ and countries’ borders. To handle this increased vulnerability, systematic approaches and decision making tools are needed to provide support in managing supply chain disruptions.more
In recent years most of the Chinese cities have shown a rapid decline in modal split of public transport as a consequence of rapid urbanization and motorization in the “socialist market economy”. It has been witnessed that cars flood into streets; road congestion, air pollution and traffic safety have become major problems in urban China.
The Deltametropolis Association initiated the SprintCity project at the end of 2009 to investigate the opportunities for successful transit-oriented development (TOD) in the Dutch metropolitan region. It is based on the diversity of station areas in the network and optimising the use of existing infrastructure. SprintCity aims to connect science and practice, so that research results can be applied effectively in the development of plans and policies regarding public transport nodes and rail corridors.
