since the analysis of complex services systems by using mathematical modeling techniques, with considering the random patterns prevailing in them, is so difficult or probably impossible, improvement guidelines are often followed based on the experts' experiences using qualitative methods. in the present paper, by employing a discrete event computer simulation methodology, criminal trial sy...

Multi-fidelity simulation is an effective approach to balancing speed and accuracy in expensive simulation, its performance affected by the quality of multi-fidelity models. Building high-quality models non-trivial, especially for complex systems, because current manual modeling methods require sufficient domain knowledge experience, increasing labor time costs. Motivated issues, this paper foc...

This paper describes a simulation specification language and execution environments that are being used to study the performance of distributed discrete event simulation. First, a simulation programming model based on Chandy-Misra distributed discrete event simulation is presented. Then, the Yaddes simulation specification language is described. Yaddes specifications are translated into C langu...

This monograph deals with the analysis by simulation of ‘rare situations’ in systems of quite different types, that is, situations that happen very infrequently, but important enough to justify their study. A rare event is an event occurring with a very small probability, the definition of ‘small’ depending on the application domain. These events are of interest in many areas. Typical examples ...

This paper describes a software enviroment devised to support parallel and sequential discrete-event simulation. It provides assistance to the user in issues such as selection of the synchronization protocol to be used in the execution of the simulation model. The software framework has been built upon the bulk-synchronous model of parallel computing. The well-defined structure of this model al...
