Analytical Queueing Model of Functioning of the On-board Navigation Complex Database

Ensuring flight safety is a priority for the development of modern both civil and military aviation. In particular, navigation systems and on-board information systems being developed to improve safety. Database is the kernel of a modern on-board complex and information system. At the initial stage of design of such systems, it is necessary to construct their functioning effective models. You can use both analytical and simulation models for it. When construct an analytical model of the database of the on-board computing complex, it is necessary to take into account many factors, including the nature of the allocating law of input flows and of the service time of of queries. In this article constructed an example of such model. To show assess the adequacy of the model, a comparison of analytical results and simulation modeling given.
