Conference paper


It is widely recognized that there is a growing interest in using the PSA in the process decision making activity to obtain more reliability during the activity of a plant. The concept is that whatever activity modifying the risk state of a plant provides more guarantee form a risk point of view if it is carried out using a probabilistic assessment rather than the deterministic methods. This concept has been extended to the test and maintenance activity because it can substantially modify the risk configuration of a plant [1, 2, 3].
