Abstract

The problem of choosing effective means and methods of monitoring the results of test diagnostics of multifunctional distributed objects is relevant and unresolved today due to the large size, the interaction of many factors and the complexity of the task. The decision of the specified tasks will allow to develop and implement as a part of the corresponding automated information system the formalized device of the description of methods and means of quality control of the managed objects and processes.
Evaluating the results of a test diagnosis is a difficult task, as it can be weighed over several stages of diagnosis and using various tools and methods. Therefore, it is important to obtain adequate estimates of atomic diagnostic objects (in the proposed diagnostic model - elementary functions), and then determine the qualitative estimates of their formed components of the types of providing the diagnostic object. To form a quantitative assessment of each level (elementary functions, groups of functions, subsystems and types of support in general), the use of additive integro-differential evaluation criterion (AIDCO), based on the results of test diagnostics of these atomic objects of control. AIDCO's linear format requires an analysis of the impact of each differential assessment (the result of the implementation of a particular test) on the integrated assessment (the degree of performance of elementary functions). At the same time there is a task of the analysis of ways of achievement of desirable (set, limit, etc.) values for achievement of necessary (set) degree of performance of elementary functions. The article proposes general approaches (within the framework of the proposed IDC) to the quantitative evaluation of test diagnosis results in relation to another subject area. Private problems of quantitative evaluation of test results and application of additive integro-differential criterion for evaluation of the degree of performance of elementary functions are also solved.

Keywords: distributed systems, elementary function, technical indicators, computer systems, control systems, Markov process, impact assessment.
