Optimization is a complex activity that aims to find the best solution for a given activity, considering allexisting limitations. The best variant possible in the set of acceptable variants is sought-out. In particular, in urban areas,optimization of land use function as the beginning of a decision-making process requires performing a great number oftasks, which minimize the risk of spatial conflicts, set at the stage of studies and analyses. Polyoptimization isoptimization with a vector objective function. The aim of polyoptimization is to find the best solution, concurrentlyapplying several criteria which, due to their limitations, are conflicting as a general rule. It leads to finding compromisesolutions (polyoptimum variants in the set of acceptable variants).In the paper the following ideas will be presented – the idea of spatial processes polyoptimization, the methods fordetermining the collection and selection of compromise solutions, the methodology for determining polioptimum statesof the space use, the possibility of using polyoptimization methods that are regarded as supporting decision-makingtools in the planning and management of space with the use of GIS tools. The Authors will show the benefits of usingthe polyoptimization. The methods of formulating and solving problems which are related to selection of optimum wayuse of land will be delivered.
