A survey of customization support in agent-based business process simulation tools
ACM Transactions on Modeling and Computer Simulation (TOMACS), Volume 20, Issue 3Article No.: 14, Pages 1–29https://doi.org/10.1145/1842713.1842717Agent-based business process simulation has grown in popularity, in part because of its analysis capabilities. The analyses depend on the kinds of simulations that can be built, adapted, and extended, which in turn depend on the underlying simulation ...

Ladder queue: An O(1) priority queue structure for large-scale discrete event simulation
ACM Transactions on Modeling and Computer Simulation (TOMACS), Volume 15, Issue 3Pages 175–204https://doi.org/10.1145/1103323.1103324This article describes a new priority queue implementation for managing the pending event set in discrete event simulation. Extensive empirical results demonstrate that it consistently outperforms other current popular candidates. This new ...

Rearchitecting the UML infrastructure
ACM Transactions on Modeling and Computer Simulation (TOMACS), Volume 12, Issue 4Pages 290–321https://doi.org/10.1145/643120.643123Metamodeling is one of the core foundations of computer-automated multiparadigm modeling. However, there is currently little agreement about what form the required metamodeling approach should take and precisely what role metamodels should play. This ...

A two-stage modeling and simulation process for web-based modeling and simulation
ACM Transactions on Modeling and Computer Simulation (TOMACS), Volume 12, Issue 3Pages 230–248https://doi.org/10.1145/643114.643118The area of web-based simulation has thrived primarily on novel methods for executing models, with contributions to both client and server side applications based in Java and other web-accessible languages. However, there has not been a commensurate ...

Cloning parallel simulations
ACM Transactions on Modeling and Computer Simulation (TOMACS), Volume 11, Issue 4Pages 378–407https://doi.org/10.1145/508366.508370We present a cloning mechanism that enables the evaluation of multiple simulated futures. Performance of the mechanism is analyzed and evaluated experimentally on a shared memory multiprocessor. A running parallel discrete event simulation is ...

Simultaneous events and lookahead in simulation protocols
ACM Transactions on Modeling and Computer Simulation (TOMACS), Volume 10, Issue 3Pages 241–267https://doi.org/10.1145/361026.361032A discrete event simulation model may contain several events that have the same timestamp, referred to as simultaneous events. In general, the results of a simulation depend on the order in which simultaneous events are executed. Simulation languages and ...

Optimizing static calendar queues
ACM Transactions on Modeling and Computer Simulation (TOMACS), Volume 10, Issue 3Pages 179–214https://doi.org/10.1145/361026.361028The calendar queue is an important implementation of a priority queue that is particularly useful in discrete event simulators. We investigate the performance of the static calendar queue that maintains N active events. The main contribution of this ...

Time warp simulation using time scale decomposition
ACM Transactions on Modeling and Computer Simulation (TOMACS), Volume 2, Issue 2Pages 158–177https://doi.org/10.1145/137926.137959In this paper we consider time scale decomposition as well as spatial decomposition to induce massive parallelism and reduce overhead in distributed discrete-event simulations. We confine our study to the Time Warp strategy and to systems where the ...

A modification of the process interaction world view
ACM Transactions on Modeling and Computer Simulation (TOMACS), Volume 2, Issue 2Pages 109–129https://doi.org/10.1145/137926.137927A formal definition of the process interaction world view is reviewed. A shortcoming of this world view is identified with respect to modularity and encapsulation. A modification of the world view that supports modularity and encapsulation is presented, ...
