The methods and algorithms for online indexes evaluation and estimation of stability, goal, and informational-technological abilities for information system

Now the important problems of structure dynamic control (SDC) theory are the evaluation and estimation of stability, goal, and informational-technological abilities for modern information system (IS). Our investigation shows that this problem can be solved by attainability set construction of SDC models. Preliminary evaluation of attainability sets for the SDC models lets allows to reduce the time (needed) required for solution of IS SDC tasks. Therefore in practice the different approximation of attainability sets are used. Methods and algorithms of evaluation of attainability sets for the SDC models are proposed.
