The basic approaches to decision making and sustainable development modeling are considered. Static spatial models include Hägerstrand model, gravity models, transportation models and location models. Dynamics of a sustainable development is considered in the Forrester’s system dynamics, in mixed integer programming models of dynamic location. Population dynamics in urban planning models is considered. Multicriteria issues of sustainable development are analyzed. Application of goal programming and other multicriteria optimization techniques are considered. GIS application for the account of the spatial factor is shown. Applying DSS (Decision Support Systems) and multicriteria spatial DSS is analyzed. DSS allow using model and solver bases for sustainable development modeling.
