Counting # of times machine is waiting on operator

I have been looking for some way to count the number of times a process, queue, or really anything is in a state of waiting due to an operator not being available. Has anyone tackled something like this that could help me out.

I am new to flexsim and not the strongest coder but I am very avid in learning so I am sorry if this is something easily tracked, but I can use any help.

Thanks,

So you are looking for a way to count, at specific times what objects are not in state waiting?
Or do you looking for a way to find out how long objects are waiting?

If the operator is used for transport, then in the transportdispatcher field (the one beside the "Use Transport" check box) you could insert the following to send a message to the object itself:

senddelayedmessage(current,0,current);

(you might want to use a very small value instead of 0)

Then in the OnMessage trigger:

if(getstatenum(current) == STATE_WAITING_FOR_TRANSPORT)
	inc(label(current,"WaitingForTransport"),1);

Be sure to add a number label on the object called "WaitingForTransport" (or whatever you want to call your label)

As an alternative to the label, I suggest using a Tracked Variable so you can obtain history, and they integrate well with the Dashboard and Experimenter.


If you are using the operator for a setup or process, I would lean towards adding an OnStateChange eventfunction to send the message from there. I have attached a model of this approach.

Thanks for the help everyone. The help is much appreciated.

I have a simple questions:
-How can i add "onStateChange" eventfunction to my object?
-Why this is not an event which i can use as a trigger?
