Math::Telephony::ErlangB is a Perl extension for Erlang B calculations.
SYNOPSIS
use Math::Telephony::ErlangB qw( :all );
# Evaluate blocking probability
$bprob = blocking_probability($traffic, $servers);
$gos = gos($traffic, $servers); # Same result as above
# Dimension minimum number of needed servers
$servers = servers($traffic, $gos);
# Calculate maximum serveable traffic
$traffic = traffic($servers, $gos); # Default precision 0.001
$traffic = traffic($servers, $gos, 1e10);
This module contains various functions to deal with Erlang B calculations.
The Erlang B model allows dimensioning the number of servers in a M/M/S/0/inf model (Kendall notation):
The input process is Markovian (Poisson in this case)
The serving process is Markovian (ditto)
There are S servers
There's no wait line (pure loss)
The input population is infinite
Requirements:
Perl
