TY - JOUR TI - Numerical investigation of reliability of pump systems from thermal power plants AU - Bugatekin Ayse T JN - Thermal Science PY - 2018 VL - 22 IS - 11 SP - 137 EP - 142 PT - Article AB - This article deals with numerical investigation of reliability of pump systems from thermal power plants. The reliability is examined by using intensity function for a system composed of n-linearly ordered pumps. The time between failures of pumps is taken as experimental. Firstly, appropriate model for the data is determined. Estimates of parameters are obtained with maximum likelihood method and intensity function models are written. Finally, reliability of consecutive 3-out-of-5:F systems are calculated for certain time periods by using the obtained intensity functions.
