摘要: An important class of system errors is defined and initial results with two prototype requirements-analysis tools are described. A requirements-specification technique that highly operational presented; it expresses the sequential behavior a in terms processes equivalent to Petri nets. Subsequent definitions based on directed graphs describe possible ways which individual might interact, thereby providing basis for can detect at end phase, rather than after delivery. >
