I work for a wireless company in the U.S. We have traditionally used Erlang B. However, I have found that we are not accounting for peakedness in traffic. I need for this to be a function that is driven algorithmically not by tables. I have found that tables do not always go high enough (e.g. 10,000 required trunks). It would require the user to input erlangs or CCS, day-to-day variation, peakedness. The output would be the number of trunks. I would like for this to be a function in either MS Excel or MS Access.
