What is the formula for Erlang C?
Work Out the Traffic Intensity (A) To work out the traffic intensity, take the call minutes and divide by 60 to get the number of call hours. So, 600 call minutes / 60 = 10 Call Hours. Now the technical unit for Call Hours is called an Erlang. So the traffic intensity = 10 Call Hours = 10 Erlangs.
What is an Erlang calculation?
An Erlang Calculator is a mathematical calculation that allows you to calculate the number of staff that you need for a given number of calls, to meet a given service level. It is based on the Erlang C formula (a derivative of the Poisson distribution) that was designed by the Danish Mathematician A.K.
How does Excel calculate Erlang C?
To get the Erlang Calculator to work you will need to have macros enabled on your computer. In Excel select Tools > Options > Security > Macro Security and then select Medium. You can then “Enable macro” when you open the spreadsheet.
How are Erlang B formula and Erlang C formula used in cellular systems?
The Erlang B formula determines the probability that a call is blocked, and is a measure of the GOS for a trunked system that provides no queuing for blocked calls. The Erlang C formula is derived from the assumption that a queue is used to hold all requested calls which cannot be immediately assigned a channel.
