The effects modeler (104) is also configured to develop search targets (312) each of which includes logical expressions of notable hazards and other factors that contribute to the cumulative effects, such as crew workload (306), safety margin (308) and/or physiological effects (310). A model analysis system (400) is configured to perform an automated analysis using the extended complex-system model and search targets, and in which the automated analysis includes a graph search of possible states of the extended complex-system model to locate search targets. And the effects assessment system (500) is configured to selectively generate a layout of failure analysis data including at least a portion of the extended complex-system model and results of the automated analysis..3~g at F- W -' Z r~ 0 cc iiia: ac~ '0 ) a: I c~PH (0 r~,t5(~) fC ~s;~ cc~ C:' ILl C) t == IC) T == (3 -V ci LL 4C)~ a: -- 0 iLl r ri ~ a Y~w -a 'S 2' rr* (9ci L -4 C)a: is H LU LU Cxl N ~0
