Simulator of Sustainable Urban Development - a tool for selecting the optimal use of land

The most commonly known definition of an optimum land use, is the one according to which, it is such a use, which from legal and physically possible forms of use that are, coherent with its purpose", generates the highest land value (Kinzy, 1992). Sustainable urban development is the optimal way to use the area, which is one in which an area is reasonably used due to the favourable and unfavourable natural and economic. Optimal use of land then is one that offers balance between the evaluation criteria. The author developed a decision algorithm that combines elements of the basic principles of optimizing the environmental, social and economic factors. Environmental (natural) and social (anthropogenic) value optimization was obtained by applying the modified method using the matrix of characteristics that cause optimal land use. Economic optimization is calculated as income optimization -maximizing income from the transformation of land use, taking into account the costs of transition. Land value for all forms of use is determined by a positive and negative influence of natural and anthropogenic characteristics. The author developed the optimizer (simulator) of sustainable urban development in order to choose the rational (optimal) area allocation. It considers three aspects to determine the optimum state of use: first, the natural and anthropogenic characteristics, second, the economic characteristics and third, the conservation of the economic - environmental balance. The developed tool for choosing the optimal use will be extremely useful in the process of elaborating the space use plans. It will select the most advantageous solution for the area and help develop solutions to address issues of not only economic nature, but also concerning environmental and human needs. The concept of the optimal spatial information system will be applied to choose the function. The main simulator application is minimizing uncertainty in the spatial planning process.
