Ensuring efficiency and reliability of equipment with optimization of integrated tests.

The paper suggests a method for optimization of the process of integrated tests for complex technical equipment of automotive, aviation, and rocket systems based on an analysis of efficiency dynamics models. The method makes it possible to determine scopes of ground tests for complex technical equipment, which are minimally required to start field tests under the necessity to combine ground and field development. Exponential models of complex systems' development are used as efficiency dynamics models for the whole testing process as well as efficiency dynamics models at various levels of the hierarchy of tests. The paper addresses an optimization task when the structure of tests at each level of the hierarchy is specified, i.e. efficiency dynamics models are determined for each level. The authors determine optimal points of transition from one level of tests to another, considering the random nature of efficiency dynamics parameters. A method for optimization using determination of the optimal scope of field tests is given.
