Method of and system for analysing for use in integrated engineering

An integrated engineering analysis system (10) that determines at least one final output value (46, 48) in response to at least one initial input value (14, 16). A first subprocesses (20) provides at least one output value (22) in response to the initial input value. A plurality of subprocesses (24, 28, 34, 40, 44) provide a plurality of output values (26, 30, 32, 36, 38, 42) in response to the output values of the first subprocess. The plurality of output values and the output value of the first subprocess are inputted into at least one of the plurality of subprocesses. A command code (52) executes each of the plurality of subprocesses in response to the output values and determines which one of the plurality of subprocesses to run and a final subprocess (44) provides a final output (46, 48). The final output is the result of a plurality of calculations executed by the plurality of subprocesses and the command code compares the final output with the initial input.
