Erlang who was the first to construct mathematical models in queueing problems.

Erlang math roof. Not all functions are provided on all platforms. We have also included a worked example in excel to help you follow the maths. In particular the erf 1 and erfc 1 functions are not provided on windows. Note that all the mathematical functions for erlang are present in the math library.

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. Mathematical functions description. A positive integer the shape and. The scale the reciprocal of the rate is sometimes used instead.

This method returns the sine of the specified value. 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. We have sold software to tens of thousands of companies in 125 countries.

Acos x float. This module provides an interface to a number of mathematical functions. The erlang distribution with shape parameter simplifies to the exponential distribution. 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.

But before we dive into the maths here is some key information about the erlang c formula and its derivation. Erlang c is perfect for calculating staffing in centres with inbound abandoning contacts such as calls which are handled by the first available agent.
