FIELD: computer engineering; simulating composite engineering installation. SUBSTANCE: method and system depend for their functioning on finding out if parameter should be entered for each component out of plurality of installation components basing on signal current structure specific for component type; parameter input is not required for output if it is found by signal current structure specific for component type that parameter of this output is independent of other parameters as of parameters of respective input or of respective inputs of component type. EFFECT: enlarged functional capabilities. 5 cl, 3 dwg
