The article presents the conception of an intelligent system for monitoring and managing the municipal waste disposal in metropolises. Applying advanced IT solutions using intelligent computational techniques enables the passage from the passive position of selfgovernment units (JST) in managing the waste disposal to the active position, especially in decision making during the problem solving of planning systems associated with the organisation management of the complex infrastructure of the waste disposal. The aim of using ICT systems is an increase in the reliability of the economy of systemic waste, monitoring in real time, the stabilization of the work of the system and the optimization of logistic and technological processes in the context of the raw material, energy application and simultaneously limiting the influence on all components of the environment.

The paper presents the adaptive, reactive computer assistance system design methodology, making modelling, analysis, and testing possible of the integrated waste management systems. The presented model is defined in a multilayer open architecture, i.e.-, it consists of the logical spaces of the constituent models (submodels) of the object classes and real processes of the waste management system. Topics covered by the paper include elements of a literature review on the modelling of systems and waste management processes, review of the programming environments employed, as well as a description of the object- -oriented waste management systems design methodology.

Finding solutions for regional waste management systems is task that requires difficult decisions. This paper presents and evaluates alternative solutions to this problem using the example of solution of this system by an example of the waste management in Zabrze. These strategies were assessed using measurable economic, environmental and social criteria. Subsequently, by using multi-criteria analysis for evaluating various aspects, the most favorable variant in terms of compromise was selected. This solution concerns the expansion of the existing waste sorting plant in the city through the addition of elements of mechanical-biological waste treatment. This option does not provide for the construction of installations for waste incineration.
