Ragulin S. Methods to improve the efficiency aircraft operation of electronic navigation systems in terms of after-sales service

Dissertation is devoted to developing methods for improving the operational efficiency of electronic navigation systems of aircraft during aftersales service. In this paper, a method for estimation of average time spent easily removable blocks in different states during the aftersales service and the analytical expressions for performance evaluation of their operation on the basis of failures that allow for process optimization during maintenance and aftersales service considers the trustworthiness of multiple control frequency control system reliability and redundancy of the structure; the method of obtaining the generalized cost performance operation at the stage of aftersales service of electronic navigation systems, taking into account, in addition to the main components of expenditure on operations maintenance indicators probability control, frequency control, costs of forming exchange fund land acquisition and automated control systems; The method of determining the ratio of aircraft readiness for any and exponential distribution laws time to time between explicit and latent failures on an infinite range of maintenance planning, which, unlike existing strategies to evaluate the effectiveness of service of electronic navigation systems during aftersales service and reliability requirements justify built controls. Got the further development of the method for assessing the operational reliability of electronic navigation systems and an arbitrary exponential distribution law uptime and availability of overt and covert failures, taking into account also the reliability of multiple control during the operation.
