this paper examines the application of a gis based planning support system, what if? tm, to evaluate alternative growth policies for sustainable urban growth in a rapidly growing city of iran. the paper describes the study area, dorood city, and the what if? model. it then explains the procedures that were used to obtain the required data and to run the model to dorood city. the paper concludes...

Production planning and control (PPC) systems have to deal with rising complexity and dynamics. The complexity of planning tasks is due to some existing multiple variables and dynamic factors derived from uncertainties surrounding the PPC. Although literatures on exact scheduling algorithms, simulation approaches, and heuristic methods are extensive in production planning, they seem to be ineff...

Planning support systems can be defined as spatial decision support systems, and they consist of three important components, namely: data, models, and geovisualisation (Klosterman 1999). In this chapter, we focus on geovisualisation in planning decision making, in which it has two roles to serve: collaboration and exploration, in particular when it is integrated with the other two components. W...
