We consider the issue of composability as a design principle for simulation. While component-based modeling is believed to potentially reduce the complexities of the modeling task, we describe a few of the complexities introduced through composability. We observe that these complexities might tend to offset the benefits of component-based modeling on a… (More)
An overview of military training simulation in the form of an introductory tutorial is provided. Basic terminology is introduced, and current trends and research focus in the military training simulation domain are described.
We consider the future directions of simulation research.
Although redundancy in model specification generally has negative connotations, we offer arguments for revising those convictions. Defining “representational redundancy” as the inclusion of any symbols not required to fulfill the study objectives, we cite several sources of redundancy, classified as accidental or intentional, that contribute… (More)
The field of parallel discrete event simulation is entering a period of self-assessment. Fifteen years of investigation has witnessed great strides in techniques for efficiently executing discrete event simulations on parallel and distributed machines. Still, the discrete event simulation community at large has failed to recognize many of these results. The… (More)
The venerable problem solving technique of simulation finds itself in the midst of a revolution. Where once it was regarded as a “technique of last resort” for systems analysis, today simulation is widely applied to support myriad purposes, including: training, interaction, visualization, hardware testing, and decision support in real-time. Advanced… (More)
This year's installment of the PADS "community assessment" looks at previous assessments and considers some current directions in distributed simulation and their possible relationship to PADS.
The nature of the emerging field of web-based simulation is examined in terms of its relationship to the fundamental aspects of simulation research and practice. The presentation, assuming a form of debate, is based on a panel session held at the first International Conference on Web-Based Modeling and Simulation, which was sponsored by the Society for… (More)
An investigation is underway regarding technologies to support the design, development and use of distributed, web-based simulations. As part of this investigation the Simjava simulation-support package has been extended to utilize the Remote Method Invocation facilities of the Java Development Kit (JDK) 1.1. Current efforts with Simjava are described and… (More)
The genesis of a research effort to develop a Java-based process-oriented simulation framework is described. A key enabler to the framework is an efficient co-routine mechanism implemented within the context of a single Java thread. A design for such a co-routine mechanism is described and some initial results of an implementation within the IBM Jikes… (More)
