Abstract: |
This paper describes and
summarises our research on enhancing the methodology of automated
discrete-event simulation and its implementation in Akaroa2, a controller of
such simulation studies. Akaroa2 addresses two major practical issues in the
application of stochastic simulation in performance evaluation studies of
complex dynamic systems: (i) accuracy of the final results; and (ii) the
length of time required to achieve these results. (i) is
addressed by running simulations sequentially, with on-line analysis of
statistical errors until these reach an acceptably low level. For (ii),
Akaroa2 launches multiple copies of a simulation program on networked
processors, applying the Multiple Replications in Parallel (MRIP) scenario.
In MRIP the processors run independent replications, generating statistically
equivalent streams of simulation output data. These data are fed to a global
data analyser responsible for analysis of the results and for stopping the
simulation. We outline main design issues of Akaroa2, and detail some of the
improvements and extensions to this tool over the last 10 years. |
