In complex technical systems, such as, for example, gas supply companies engaged in the use, processing and transportation of gas, improving the quality of functioning is largely due to the fact how effectively be able to use resources management when abnormal and emergency situations. Implement management quick and timely action controller and related services to a large extent depend on the quality of information available on the state of the system, keeping in mind those of its features that can adequately classify and identify the situation adequately assess the state of the system and choose the most optimal conditions prevailing in framework for action. The modern development of information technologies and means of automation and computerization can solve the problems associated with providing efficient and trouble-free operation of a complex technical system, timely response to dangerous situations, control of the consumption of resources, taking into account a comprehensive plan parametric, functional, topological and other characteristics controlled system and its objects in the interaction and relationships, creating static and dynamic images of the object, allowing combined with modeling processes to implement current and forecast assessment of the state of the system with sufficient accuracy and reliability. The paper presents a model of quality assessment of complex technical systems. Evaluation of the status of objects and the system as a whole by means of intermediate scales numerical evaluation as qualitative estimates are associated with their quantitative equivalents, allowing the algorithm to construct a formal transfer. State system objects viewed through the prism of determining compliance parameters of the object of one of the areas of the state, taking into account the possible modes of operation of the system. This data is the variable quality of the order given on the set of equivalence relations items, which leads to the qualitative nature of the assessment.
