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.
