Using failure probability and system reliability data can assist you in addressing the undesirable events or challenges.

These challenges are more compounded where manual methods of fault isolation and risk analysis in large and complex systems are not viable. To improve system safety and reliability, designers and analysts have to make better-informed risk assessment decisions based on quantified evaluations of the risks and effects associated with alternative designs and other risk-mitigating actions. To address safety and the ways failures or undesirable events could occur and thereby, trying to avoid them can be very challenging.
After events are added, they can also be changed to gates by clicking on basic event circle to pull down the palette of gates and events. A quick way to add a large number of gates is to use the Edit, Input option. Input Fault Tree Logic: Input Fault Tree Logic Fault tree logic may also be entered using the following input methods: In the toolbar click on the yellow down arrow key (with plus sign) to convert an event to a gate Press the Ctrl key and double click between two existing gates (be careful not to click in a description box).
