Survivability study of a Water Cleaning Facility using Fluid Stochastic Petri Nets

This paper investigates the survivability of a water cleaning facility using Fluid Stochastic Petri Nets (FSPN). Water cleaning facilities are responsible for providing drinking water to a specific district. The provided service is very important and makes such facilities belong to a nation’s critical infrastructures. Therefore, such a facility should be able to recover in a timely manner after the occurrence of disasters. The use of FSPNs in survivability research is new and promising due to its general applicability. In this paper we model and analyze the survivability of the last phases of the water cleaning process in a Dutch water company. Analysis results identify the weaknesses of the process and redundancy is suggested to improve the survivability.
