Four-state exploitation strategies of maximize of the coefficient of the readiness with the regard of economic conditions

Electronic systems work in different conditions of exploitation. Because of specific nature of their application (such as transport for example), they should be characterized by a high level of coefficient of the readiness. When carrying out a proper reliability analysis of systems can be determined such reliability structures, which will be characterized by the appropriate values of rates of reliability. Such an approach provides to improvement of the reliability of the designed systems. However not to the full extent, it is not possible to achieve the system's readiness at the appropriately high level to the full extent. The paper presents a methodology to optimize the process of exploitation these systems, taking into account economic conditions, such as of financial expenses designed on periodical reviews and the effectiveness of their use. There is presented the dependence that maximizes the value of the coefficient of the readiness in the defined reliability (failures rate), exploitation (intensity of repairs, intensity of maintenance service) and economic conditions (financial outlays earmarked for periodic inspections).
