Design of State Diagram Facilities in Sced

Various possibilities to support the automated construction of state diagrams of the OMT method are considered. The proposed facilities are planned to be included in a prototype environment whose basic components are editors for scenarios and state diagrams. The considered support covers automatic means for synthesizing a state diagram on the basis of scenarios, for making the state diagramas compact as possible, for determininga satisfactory layout for the state diagram, and for maintainingconsistency between scenarios and state diagrams. The prototype environment| called SCED| currently supports editing of scenarios and automatic synthesis of state diagrams.
