Math::Telephony::ErlangB 0.06

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, 1e-10);
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
- Theres no wait line (pure loss)
- The input population is infinite
