Development of Methods for Evaluating Reliability Indicators for Network Switches Using the Bellcore/Telcordia Standard

The final qualifying work is devoted to solving such a problem as the development of a methodology for assessing reliability indicators using the Bellcore/Telcordia standard, and designed to calculate the reliability indicators for network switches. The purpose of this work is to compose documentation that consists of recommended reliability prediction methods for devices, units and serial systems. This project also enables reliability engineers to save time and money by using developed automatic reliability prediction procedure in accordance with the recommendations. Initially, it was necessary to develop a methodology for calculating reliability indicators and develop a report structure, briefly describe the methods and give basic definitions. This includes defining the formulas and algorithms that will be used to calculate the indicators, and specifying the necessary input variables. Then develop special software for calculating reliability indicators based on methods from the Bellcore/Telcordia standard. The program is a software tool for working with Microsoft Excel spreadsheets that automates reliability forecasting procedures. Also, it is needed to analyze network switches and test on the example of a study of the average operating time for failure for switches of an industrial data transmission network. At the end, conduct a comparative analysis of calculations according to different reference books, compare with traditional methods and draw conclusions.
