Optimization of data transmission system information parameters for complex technical system’s state diagnosing

Abstract

Complex technical systems are often operated in tense, abnormal conditions, with a large number of correlated parameters. Timely and high-quality diagnostics, including remote diagnostics, of complex technical systems components can increase their reliability. To successfully solve the problem of such systems trouble-free operation in abnormal operating modes, it is necessary to maximize the use of information technologies with software and hardware diagnostic modules. In order to make a reasonable choice of system’s information parameters for diagnosing complex technical system’s state it is necessary to solve the problems of multi-parameter, multi-criteria optimization data transmission systems. Such task aimed for increasing the speed, minimizing the error and risk of system’s elements failure, and maximizing the transmitted information protection. The objective function of optimizing the information parameters of the data transmission systems for remote diagnostics is its multi-parameter optimization of the variables that affect the remote diagnostics of all system’s efficiency. Solving the problem of optimizing the remote data transmission systems for remote diagnostics information parameters based on the developed model allows us to find several Pareto-optimal solutions for quality indicators, which are affecting the efficiency of the data transmission systems for remote diagnostics. Basic parameters and characteristics of the data transmission system are the optimal number of devices types for monitoring complex technical systems technological parameters, topology efficiency, throughput, speed, error of the data transmission system, the risk of component failures and the information protection effectiveness in the remote diagnostics system.
