Process(过程)：A sequence of interdependent and linked procedures which,at every stage,consume one or more resources to convert inputs into outputs.These outputs then serve as inputs for the next stage until a known goal or end results is reached.. Path(途径)：the sum of the processes for the system from an initial state to a final state.
