"Event based simulations: enabling improved development planning and partnerships";
Vortrag: Internationale Konferenz zu Stadtplanung und Regionalentwicklung in der Informationsgesellschaft, TechGate Vienna, Wien; 20.05.2007 - 23.05.2007; in: "Real Corp 2007: To Plan Is Not Enough, 12. Intern. Konferenz zu Stadtplanung und Regionalentw. in der Informationsges.", M. Schrenk, V. Popovich, J. Benedikt (Hrg.); (2007), ISBN: 978-39502139-3-5; S. 17 - 23.

Even though conomic appraisal in the real estate field is currently based on the assumption that the built environment is static, buildings and its management represent a dynamic "system" whit a "behavior" we are able to design and develop. The fitness of this system, its ability to react to changing user demands, demographic development, etc. is imperative for sustainable environmental, economic and social urban development. Due to missing methods and technology the flexibility of property and the facility management behavior are either not considered or play a very minor role in the practice of the real estate development.
In the research and development project "discreteFD" at the Swiss Federal Institute of Technology Zurich (ETH Zurich) discrete event simulations were developed in cooperation with the Swiss industry partners SUVA and redKG and the German BASF AG, which map "system behaviour" of facilities and facilities management across the life cycle of a property. As a consequence, urban real estate development concepts can be optimized for sustainable use over a single day and the entire life cycle. The consequences of development plans and their sensitivity concerning possible events can be simulated over time. Alternative concepts become much more transparent for investors as well as for urban planners. New avenues of communication are opened and new partnerships are formed.
Empirical tests of the new simulation models and the software tools proved that the complex dynamic system of Real Estate and Facilities Management can be evaluated more precisely via discrete event simulations, thus achieving an enormous optimisation potential for Real Estate Development (RED) and Facilities Management. The congress contribution focuses on possible applications of the event based simulations in urban development projects and public private partnerships.
