  A simulation tool based on GEMC framework to describe the MRPC telescope of
the Extreme Energy Events (EEE) Project is presented. The EEE experiment is
mainly devoted to the study of the secondary cosmic muons by using MRPC
telescope distributed in high schools and research centres in Italy and at
CERN. This takes into account the muon interactions with EEE telescopes and the
structures surrounding the experimental apparata; it consists of a dedicated
event generator producing realistic muon distribution and a detailed geometry
description of the detector. Microscopic behaviour of MRPCs has been included
to produce experimental-like data. A method to estimate the chamber effciency
directly from data has been implemented and tested by comparing the
experimental and simulated polar angle distribution of muons.
