System, method and computer program product of performing situational control using a state diagram

A system of performing situational control using a state diagram, applied to a graphic control system, the system comprising at least:

• a state edit module, used to provide a state diagram for editing a control logic, the state diagram comprising a plurality of state nodes, at least one state transfer indication and internal computing function in each of the state nodes;
• a target defining module, used to define a decision role executing the control logic;
• and
• a situational control module, used to transfer a control to at least one of the state nodes according to the at least one state transfer indication, and then make a common decision by executing the internal computing function of the at least one of the state nodes getting the control, to perform the situational control for the decision role.
