What is Changepoint

This chapter presents the questions of aviation radioelectronic equipment operation. Operation is the main stage in the life cycle of equipment. This stage is the longest in time and very significant in terms of the costs for equipment reliability providing. Control influences are realized in operation system to provide the efficient functioning of the equipment. The operation system is complex in structure intelligence system and is the object of design and modernization. The chapter deals with the structure of the operation system and its elements interconnection and discusses the models of diagnostic variables, reliability parameters for the case of changepoint presence. An important issue during design and improvement of operation systems is the selection, evaluation, and support of the efficiency indicator. This chapter concentrates on the efficiency indicator substantiation taking into account the effectiveness and operational resources costs. Three data processing strategies analysis allowed choosing the most rational option from maximum efficiency point of view.
