For simulation and/or control of automated physical ("real") systems, a hierarchical control system is embodied in computer software executable on a general purpose computer. This is suitable for control and monitoring of complex physical systems without use of elaborate interface circuitry. An ergonomic user interface (7) graphically closely adapts to the particular automated system which is being simulated and/or controlled. The automated system is partitioned into various sub-elements, each of which typically represents a physical part, for instance, pumps or gauges or tanks in a chemical processing system. These elements are arranged in a hierarchical structure of elements. Each element has associated with it the intelligence and logic, in terms of the computer software, needed for its corresponding physical functionality. The function of each element depends on its current state as defined by the computer software and the states can be changed by commands as in the physical system.
