1. A method of generating a graphical presentation of a fault tree map for use in technical system or installation design and/or diagnostics, said method comprising: (a) creating a fault tree including cut sets and events important evaluation; (b) analyzing the fault tree to determine latent failures, repeated events and gates; (c) generating, with a computer, a compact map of said fault tree, said compact map graphically indicating evident event (failure) type with a first connector symbol and indicating events with exposure time in excess of flight duration (mission time) with a second connector symbol different from said first connector symbol; graphically indicating logic gates with predetermined symbols different from Fault Tree gates image; and (d) graphically presenting said compact fault tree map.
