Mathematical modelling of critical infrastructure reliability

Popis výsledku v původním jazyce

Safety and dependability of technical systems are key aspects when it comes to a system quality. Critical infrastructure covers many parts such as mains, transportation system, networks and buildings. In our paper, we put an emphasis on a water distribution network where high availability, reliability and safety are very much demanded. Such network usually consists of more lines with different hierarchical importance and age. Moreover, various materials are usually used to manufacture water pipes. The in-field operation of a water distribution system is not very well recorded since it usually does not contain all details about failure occurrences. We have interesting water distribution system recordings covering a wide time span, but, unfortunately, they provide only the numbers of failures during respective months. In this paper, we apply a selected form of dynamic linear models-a modified Kalman filter with the implementation of a structural break point.
