entity queue time

[ezel11]

hi all,

i am modelling a call center simulation,and i have trouble with abondened calls.
i need a variable that measures the time that entity waits in the queue,and just before the entity goes to get service it checks p=probability(1-exp(Q*queue time of the person)).
the entity will get service with probability 1-p and abondenes with probability p.

Can you help me on the variable of queue time?

THNK YOU

hi all,

i am again asking about queue time of an entity.
i find entity wait time as total wait time of an entity in the process.
i wanna ask that if it is the total of all waiting times of the entity at all queues or is it possible that it can also show the wait time of a process if i used it before that process?

i really need help on this subject..

thank you..

Entity.WaitTime—Entity waiting time attribute stores the total time accumulated in queues (waiting areas) as well as processes and delays designated as Wait. Therfore it will not work for your problem.

You can assign an attribute (TNOW) to an entity just prior it enters the queue. Then you can use AQUE ( Queue ID, Rank, Attribute Number ) to evaluate the waiting time of the queued entity in this specific queue.
Equally good you can evaluate Entity.WaitTime prior it enters the queue and assign the value as attribute. Then using the same logic as previously you can evaluate a difference.


Can you please write what kind of blocks (model logic) are you planning to use to evaluate your p expression when entity is about to leave the queue and enter the service? .
