Evolutionary network model of testing of the distributed information systems

The Automated Systems of Technical Diagnostics (ASTD) of the dynamic distributed information systems (DIS) need the operational reconfiguration corresponding to changes of DIS. As a result, support of ASTD also requires the up-dating, advancing changes of DIS. In this work, development of the network model of testing is provided, allowing to reduce time of synthesis of tests for DIS. The Model is based on the evolutionary organization of testing for a network of automata. The model assumes creation of component test evolutions in interaction with evolutions of realisation and transportation on an automata network in case of repeated use of nodal behavior. The conditions of realysability and transportability are defined for automata tests in a network model of testing in addition to a set of evolutionary component models of testing. Models are provided at the first level of component model of testing for the separated component automata of a network, at the second level of cooperative model of testing for the component automata in a networked environment of the realyzing and transporting subnets, ay the third level of a network model of testing on the basis of combination of cooperative models of testing of the second level. The evolutionary network model of testing allows to define conditions of synthesis of network behavioral tests for DIS and to decompose of the task of synthesis of tests for DIS with reduction of its complexity. The evolutionary search of this synthesis allows to reduce expenses of time and resources in comparison with the determined approach in most cases real systems.
