Control of complexity in virtual organizations : the role of enterprise modelling

In general it can be staled that re-design and optimisation of a (virtuaI) enterprise is not facilitated but hindered by infonnation systems. Too much of lhe 'way of working' of the existing situalion is tixed in the existing systems to aJlow for easy changes. This problem is reinforeed by the requiremenls for differentiation between similar but not identical business processes that further emphasize the need for increased flexibility, and the problems as caused by the current generation if enterprise information systems. Adequale redcsign of both the business processes of a (virtual) organization and the associated infonnation systems requires enterprise modelling. In this paper we will, based on experiences gained in the area of product data modelling, develop a number of requirements for enterprise modelling methodologies. reference architectures, and languages. In this we will mainly focus on the areas of semantics, dynamics and complexity

International Course on Water and Water Management in the Philippines 2014

Since 2011, the Faculty of Social Sciences (FSW) and the Institute of Environmental Sciences (CML) of Leiden University, in cooperation with Isabela State University and the Mabuwaya Foundation in the Philippines organize an annual month–long international, interdisciplinary field course on sustainable development, water issues and water management in the Cagayan River basin and Sierra Madre Mountains in Northeast Luzon in the Philippines. Thirty students usually participate in this course, 15 through Leiden University and 15 through Isabela State University. The students are enrolled in different studies, encompassing social, natural and applied sciences. The annual report contains background information about that year’s course, all student reports and the online blog that the students maintained during the course.</p
