Home Free calculators Products Tech. The gamma distribution generalizes the Erlang distribution by allowing k to be any positive real number, using the gamma function instead of the factorial function. In fact, this distribution is sometimes called the Erlang- k distribution e. This work on telephone traffic engineering has been expanded to consider waiting times in queueing systems in general. A windows version ditribucion available for immediate download at just 99 US Dollars.

These calculators are available for 99 US Dollars. The Erlang distribution, which measures the time between incoming calls, can be used in conjunction with the expected duration of incoming calls to produce information about the traffic load measured distribicion erlangs. Erlang to examine the number of telephone calls which might be made at the same time to the operators of the switching stations.


Because of the factorial function in the denominator, the Erlang distribution is only defined when the distribjcion k is a positive integer. Unknown Blocking Unknown Lines Unknown.

An asymptotic expansion is known for the median of an Erlang distribution, [1] for which coefficients can be computed and bounds are known.

Please help improve this article by adding citations to reliable sources. For example, if from your call logger, you know that the Busy Hour Traffic is 10 Erlangs, and you want to know how many lines are required in this trunk group if you are prepared to tolerate 2 calls being blocked in every calls attempted then: Pages using deprecated image syntax All articles with unsourced statements Articles with unsourced statements from Disribucion Articles needing additional references from June All articles needing additional references Articles lacking in-text citations from June All articles lacking in-text citations.

This can be used to determine the probability of packet loss or delay, according to various assumptions made about whether blocked calls are aborted Erlang B formula or queued until served Erlang C formula.

The probability density function of the Erlang distribution is. Click on the Unknown radio button representing the unknown variable. The cumulative distribution function of the Erlang distribution is.

For a running record of the results calculated, press the Results button. From Wikipedia, the free encyclopedia. Busy Hour Traffic in Erlangs is the number of hours of call traffic there are during the busiest hour of operation of a telephone system.

The Erlang distribution is the distribution of the sum of k independent and identically distributed random variableseach having an exponential distribution.

When you press the Calc button, 17 will be displayed in the Lines edit box indicating that 17 lines would be required in this trunk group.
