Introduction

Algeria Telecom is the monopoly of fixed telephony and Internet in Algeria. At time when competition in mobile telephony becomes greater, Algeria Telecom was part of a policy of continuous improvement of its operating system in order to ensure better quality services to its customers.
This internship was done in a period of 30 days where westudied the queues of customers at the ACTEL Aisset Idir. During the early days we looked at the various company departments, then, at the ACTEL, we carried out the collection and data processing, system modeling, simulation and processing results, and then we proposed solutions for improving service performance.
In the first part of the report we will present the company Algeria Telecom and theACTEL Aisset Idir, then in the second, we will present the study through its various stages.
