Safety Analysis of Complex and Software Intensive Systems

May 26, 2011

UL Advisory Services provides safety analysis of complex and software intensive systems for manufacturers looking for assurance of the quality of their software and/or complex systems apart from any certificate or mark. This service may include fault-tree analysis, failure mode and effects analysis (FMEA), and hazard and operability analysis (HAZOP), among other things.

“Although these analytical methods by themselves may be straightforward, applying them can be difficult,” says Thomas Maier, principal engineer, functional safety at UL. “You can understand the principles of these methods in the course of a day; but, for them to yield what you are looking for requires a world of experience and skill. This comes by having used these methods on complex systems (i.e., software-based systems, many times over many years) to assure the analysis is not overdone or underdone. It must be done in the correct way to get meaningful results, and no one has more experience in applying these techniques to complex systems than UL.”

Kevin Connelly, business development manager at UL, notes that it is easy to underestimate the nuances of these complex systems. “These systems are difficult, and to do these analyses successfully requires more than peripheral experience,” he says. “If you’re planning on ultimately submitting for a functional safety certification, then you need to understand the requirements intimately to avoid the time and cost of having to go back and redo analytical work. That’s where UL can help, because of its unparalleled experience.”
