ABSTRACT: The great number of simulation methods, techniques and tools based on statistics have been proposed and used for investigations of systems operation and behaviour. Unfortunately, in cases when the necessary amount of statistics is not available simulation is not giving the expected results and frequently is not applicable at all. In these situation qualitative approach starts to play an important role. The main advantage of structural modelling is that all needed data for analysis are captured in the systems structure itself, that is, no numerical data (statistics) are needed at all. The goal of structural modelling methodology is to provide the framework for systematic, domain model based knowledge acquisition, representation and processing based on a set of related structural models. Four aspects are taken into consideration: systems structure, behaviour and functions, and causal knowledge. This article is devoted to the applications of structural modeling which includes several stages of analysis. There are given results of made analysis and some new ideas (based on got results) about structural models decomposition are presented


KEYWORDS: Heterogeneous systems, structural model-based reasoning, qualitative analysis, model of morphological structure, nodes, relationships, decomposition
