ABSTRACT
In this paper, we investigate output accuracy for a Discrete
Event Simulation (DES) model and Agent Based Simula-
tion (ABS) model. The purpose of this investigation is to
find out which of these simulation techniques is the best
one for modelling human reactive behaviour in the retail
sector. In order to study the output accuracy in both mod-
els, we have carried out a validation experiment in which
we compared the results from our simulation models to the
performance of a real system. Our experiment was carried
out using a large UK department store as a case study. We
had to determine an efficient implementation of manage-
ment policy in the store's fitting room using DES and
ABS. Overall, we have found that both simulation models
were a good representation of the real system when model-
ling human reactive behaviour.
