- Stop elevator at Floor (Ta=50msec)
- Execution time: Total execution time Ca2msec (Arrival Sensors Interface){5msec (Elevator Controller) Execution utilization Ue= Ca/Ta=7/50=0.14
- Preemption by higher priority tasks with longer periods. Preemption time Pa=3 (Elevator Buttons Interface). Preemption utilization Up=3/50=0.06
- Blocking time: Total worst-case blocking time Ba= 6msec (Elevator Manager). Worst-case blocking utilization Ub = Ba/Ta=6/50=0.12
