An Operating Procedure Synthesis Method for Shutdown of Boiler Plants

Abstract A method is proposed which automatically synthesizes a safe operating procedure based on the knowledge of human operators that are generalized and classified hierarchically. The proposed method automatically generates and orders subgoals that must be achieved between the initial state and the goal state. It searches for the primitive operation device to achieve each subgoal subject to the operational constraints, and evaluates the safety of the operation. A case study of automatic synthesis of a boiler plant shutdown procedure shows the industrial applicability of the proposed method.
