A Time Refinement Framework Based on iUML-B State Machine

Table 5

The evaluation of various real-time Event-B modeling methods.

Methods	Evaluation standards
	S1	S2	S3	S4	S5	S6
M1	Event-B code	Event-B code	N/A	N/A	N/A	N/A
M2	Event-B code	Duration	N/A	N/A	N/A	N/A
M3	ERS diagram	Three patterns	ERS diagram	N/A	TP plug-in	Mostly automated
M4	ERS diagram	iUML-B state machine	ERS diagram and iUML-B state machine	ERS Diagram and iUML-B state machine	tiGen plug-in	Fully automated
M5	iUML-B state machine	iUML-B state machine	iUML-B state machine	iUML-B state machine	N/A	N/A

M1: time constraints method; M2: duration pattern method; M3: Time Properties method; M4: Time Interval method; M5: iUML-B time state machine method.
