So all of the below examples will use the import statement to import all the methods in the math library. A positive real number the rate. Erlang c is perfect for calculating staffing in centres with inbound abandoning contacts such as calls which are handled by the first available agent. The erlang distribution is a two parameter family of continuous probability distributions with support the two parameters are.

Not all functions are provided on all platforms. Sometimes the erlang distribution is defined as the gamma distribution with the density frac alpha n gamma n x n 1 e alpha x quad x 0 it is named for a. A positive integer the shape and. The scale the reciprocal of the rate is sometimes used instead.

In particular the erf 1 and erfc 1 functions are not provided on windows. This module provides an interface to a number of mathematical functions. The erlang formula assumes that the calls are homogeneous and the agents have effectively one skill. The erlang c formula is quite complex to look at but can be straightforward to apply if you follow these easy steps.

Note that all the mathematical functions for erlang are present in the math library. We have also included a worked example in excel to help you follow the maths. The erlang distribution with shape parameter simplifies to the exponential distribution. We offer erlang traffic calculators and add ins for excel and have become the preferred supplier of industry standard erlang calculation solutions for the world s largest companies.

But before we dive into the maths here is some key information about the erlang c formula and its derivation. Acos x float.
