Abstract(in English) | In order to analyze exhaustively affects of failures in small embedded systems, we proposed SASTD (Safety Analysis method based on State Transition Diagram). SASTD assumes that system specifications of an embedded system have been modeled as only one state transition diagram. Therefore it is difficult that we analyze exhaustively the state transition diagram including many states and state transitions by using SASTD. In many cases, a hierarchical state transition diagram is used to reduce the number of states in a state transition diagram. In this paper, we propose SAHSTD (Safety Analysis method based on Hierarchical State Transition Diagram). We applied both SASTD and SAHSTD to the system specification of an electric boiling pot, and compared the results of them. Consequently, we confirmed that all deviations derived by SASTD could be also derived by SAHSTD. Since several system states with same characteristics were integrated to hierarchical system states, the number of derived deviations that analyzer must decide its severity could be reduced from 92 to 61 in the analysis for system states, and from 284 to 1 34 in the analysis for system state transitions, respectively. |
