	~~== Phase with Failure or Success Paths ==~~		#REDIRECT [[Example_Using_Success_Failure_Paths_in_Phase_Diagrams]]

	~~==== Purposes ====~~

	~~The purposes of this example are to illustrate how to apply failure or success paths in Phase simulation.~~

	#~~For a failure path, on system failure, system go to somewhere immediately when failure occurs.~~
	~~#For a success path, if there is no system failure during this phase, system goes to somewhere by the end of the current phase.~~

	~~==== RBDs for Phase and settings ====~~
	~~The RBDs for Phase 1 and Phase 2 are as followings:~~
	~~[[Image:RBD_for_Phase_1_and_2.png\|thumb\|center\|500px]]~~

	~~In Phase 1, Block A follows Weibull distribution with Beta = 1.5 and Eta = 1000 hours. Block B follows Weibull distribution with Beta = 1.5 and Eta = 1200 hours. No maintenance.~~

	~~In Phase 2, Block A follows Weibull distribution with Beta = 1.5 and Eta = 900 hours. Block B follows Weibull distribution with Beta = 1.5 and Eta = 1150 hours. No maintenance.~~

	~~==== Example 1 ====~~

	~~The Phase diagram is as followings: [[Image:Phase Example 1.png\|thumb\|center\|500px]]~~

	~~Maintenance phase has a CM with duration 80 hours and PM with duration 20 hours for both Block A and B.~~

	~~Phase 1 has duration 100 hours and Phase 2 has duration 500 hours.~~

	If there is no failure in Phase 1, upon finish, it goes to Phase 2. If there is a failure in Phase 1, it would go to Maintenance Phase 3 immediately. If there is no failure in Phase 2, upon finish, it goes back to Phase 1. If there is a failure in Phase 2, it would go to Maintenance Phase 3 immediately.

	~~The Block Up/Down plot is as followings:~~

	~~#At the first cycle (0-100 for Phase 1 and 200-600 for Phase 2), there is no failure, thus after Phase 2, Phase 1 is executed (back to Phase 1 after this cycle).~~
	#At 616 (Phase 1 of the second cycle), Block A fails. System doesn't enter Maintenance Phase 3 immediately because in Phase 1, Block A and Block B are parallel. Only failure of Block A doesn't bring system down.
	#At 700, after Phase 1, system goes into Phase 2. In Phase 2, failure of Block A (passed from Phase 1) bring the system down because in Phase 2, Block A is in series with Block B. Thus system goes into Maintenance Phase 3 immediately. Block B is not down, thus it gets PM with duration 20 hours. Block A gets CM with duration 100 hours.
	~~#At 1669, Block A fails in Phase 2 which bring down the system and system goes into Maintenance Phase 3 immediately. Block A gets CM and Block B gets PM.<br>~~

	~~[[Image:Phase Up Down plot for Example 1.png\|thumb\|center\|500px]]~~

	~~==== Example 2 ====~~

	~~The Phase diagram is as followings: [[Image:Phase Example 2.png\|thumb\|center\|500px]]~~

	Everything is the same as that in Example 1 except that the path from Phase 2 to Maintenance Phase 3 changes from failure path to success path. This means that whether or not there is a failure in Phase 2, the system would go to Maintenance Phase 3 after Phase 2. But if there is a  failure in Phase 2, system would go to Maintenance Phase 3 after Phase 2, not immediately.

	~~The Block Up/Down plot is as followings:~~

	#At 219, Block A fails in Phase 2. This failure brings the system down. However, since the path from Phase 2 to Maintenance Phase 3 is a success path, system doesn't go into Maintenance Phase 3 immediately. It would go into Maintenance Phase 3 after the Phase 2. Block A gets CM and Block B gets PM in there.
	#At 1934, Block B fails in Phase 1. This failure doesn't bring system down because in Phase 1, system is in parallel structure. After Phase 1, system goes into Phase 2 and the failure of Block B brings system down in Phase 2. However, system doesn't go into Maintenance Phase 3 immediately because the path between them is success path. System goes into Maintenance Phase 3 after Phase 2 and Block B gets CM and Block A gets PM there.[[Image:Phase Up Down plot for Example 2.png\|thumb\|center\|500px]]
