- Abstract
- The Ship Applied Fire Engineering (SAFE) computer program evaluates the probability of limiting the spread of fire from one compartment to another throughout a vessel. The results from SAFE are expressed in terms of the frequency of expected loss of each compartment. To evaluate these frequencies, it is necessary to determine the cumulative probability of loss of each compartment in the ship as a target from all possible fire paths from all possible rooms of origin. The existing algorithm in SAFE for calculating the loss of target compartments, referred to as the "Cumulative L-Curve Algorithm", errs on the conservative side since it permits the contribution of a particular compartment to be counted more than one once toward the total probability of loss fro a target compartment. The approach selected to develop a mathematically valid cumulative L-Curve algorithm utilizes the mathematical tools of reliability theory, specifically for interconnected systems.
