ErlangC

 

This calculator implements the Erlang C Traffic Model used in Call Centers design.

 

Input:

Average duration of each call * sec.
Number of calls *
Number of agents/operators *
Maximum delay time (t) sec.

 

Results:

 

 
Call delay probability %
Average delay for all calls sec.

Calls answered within (t)

%

obs.: Use the dot format (0.0) for decimal numbers.

 

Example

 

Considering a Call Center with average call duration of 240 seconds, receiving 1300 calls during the peak hour and having 100 agents / operators available, the average delay for all calls will be 1.97 seconds and the probability of having a delayed call is 11 %.

 

If a maximum delay time of 20 seconds is required, 96.4 % of all calls will be answered within that delay time (< 20 seconds)..
