PURPOSE: To easily manage the operation of a component whose state transits in parallel nd to attain the control of execution of it by allowing a transition driver to make transition from information of a hierarchical tree structure and a decision table, conducting a prescribed process and repeating finally the state transition.
CONSTITUTION: A transition driver 215 makes a transition from information of a hierarchical tree structure 210 and a decision table 220 according to a prescribed procedure such as initialization and current state setting depending on an event received by an event handler 225 to update a current state value 205 and the event is stacked to a event stack 230. When an event is propagated to an upper layer, the transition drive 215 receives the event from the event handler 225 to repeat the processing of the state transition. An attachment operation program 235 is a program started associated with the transition and the transition driver 215 commands starting.
