Several important changes have recently influenced urban planning and redevelopment process. At first, the scope and scale of urban redevelopment projects has increased. Secondly, a traditional linear planning process from government to the building industries has been replaced by public-private collaborations that changed the characteristics of the developer and governmental agency; their roles play now the major influence in urban development processes. Therefore, an important cause for stagnation in redevelopment of Brownfield is the lack of consensus amongst key actors due to shared, overlapping concerns or individual conflicting interests. In particular, this research focuses at possible stagnation in relation to: (a) the features of a Brownfield, (b) the preferences of two groups of actors and (c) the characteristics in the negotiation process between the two groups of actors. To structure the features a Fuzzy Delphi Method is used. Stated Choice Method provides an insight in the individual preferences of both stakeholder groups. The outcomes of the decision-making process are not only depending on an individual choice made, but also including the influence of the choices of an actorís opponent. Therefore, we focus specifically on non-cooperative games (Game Theory) aiming on finding possible sources of conflicts in negotiations concerning Brownfield redevelopment. Based upon the findings on conflicting games, interaction between the selected two actors will be simulated, calculated and modeled. The final outcomes of the research project will assist decision makers to predict possibility of stagnation and to overcome the challenges of conventional negotiation. The construction of alternative plan proposals within these models is a relative unstructured process. Little work has been done to develop models that systematically relate the characteristics of the Brownfield areas and redevelopment plans to the behavior of actors thereby giving insight in the most important points of interest and in possible sources of conflicts.
