Subtle system dependencies might be overlooked, leading to unduly optimistic estimates of dependability and risk related measures; also sometimes being in a particular state for too long a time can result in a failure state, which is difficult to model in an event tree.d. Issue 00 Rev.0Course Title 1 This aspect should be covered by fault tree analysis which can then be linked to the ETA;f. Although multiple pathways to system failure may be identified, the levels of loss associated with particular pathways may not be distinguishable without additional analysis; however, awareness of such a need is required.This is a platform for people working in the pharmaceuticals industry for Discussions, Jobs, News updates, Professional Profile display space and company business pages.
