Model based diagnosis is a very hot topic right now in the world of system engineering; through RODON the user is provided with the necessary tools to accomplish this. With this software one can model a hydraulic system and auto-generate fmea (failure-mode-effect-analysis). The old fashioned way for solving this procedure is with pen and paper and that’s a very time-demanding activity. In addition to previous attributes of traditional failure-mode-effect-analysis: The complexity-grade is increasing fast in large machinery. Due to the origin of the paper; i.e. as a product of a master thesis; a huge effort has been put in to understand how RODON works; and how hydraulics best should be modeled to provide the user with as much information and accuracy as possible
