Project X - Essay Example For the success of our project X, whose goal is to create a defense mechanism to save major important cities of the US from enemy missile attack, it is of utmost importance that we consider these methods and identify the potential risks for project X. Quantitative Risk Assessment System (QRAS) is a personal computer (PC)-based software tool for performing Probabilistic risk assessment (PRA) supporting decision on funding -- cost-estimation steps. QRAS is designed to bridge the gap between professional risk analyst and the design engineer. It is a user-friendly, graphical interface design, used by managers and engineers with minimal specialized risk assessment training. Its front-end is a graphical point-and click tree system model, combined with elements, subsystems, and sub-systems – the system hierarchy used to attach known accident initiators or failure modes. This hierarchical feature helps in making a Master Logic Diagram. Mission profiles can be set on sub system run times – a Mission Timeline module feature. The potential risks of failure probabilities can be calculated with the Timing data in other parts of the QRAS. This tool helps in constructing Event Sequence Diagrams (ESDs), explaining the scenarios lea ding to catastrophic failures or success of pivotal events showing fail-safe design or even emergency procedures and reasons of failures. Fault trees are built with graphical interfaces, which are joined to ESD models. The different features of QRAS are quantified to check failure probabilities in physical variables, providing fast and exact solutions. This software tool generates conventional event tree, minimum cut sets of system fault trees and ESD end states automatically for the risk scenarios. The software tool QRAS can identify the potential best estimate of catastrophic failure probability of a mission like the loss of Mobile Housing Unit (MHU). It would calculate a system’s top-level and intermediate
