The concept of strong groups is introduced to describe the structure of simulation models. It is shown that logical processes within strong groups process at approximately the same rate and that different strong groups can progress at different rates. An algorithm based on the rates of the strong groups is presented to balance the load among the physical processors and for flow control.

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 computersimulation during 11-14 January 1998 in San Diego, California. While no clear "winner" is evident in this debate, the issues raised here certainly merit ongoing attention and contemplation.

The authors, six simulation professionals, present their views on the directions that they believe that verification, validation, and accreditation research should take. Two of the six are active verification, validation, and accreditation researchers from academia, two develop industry simulation models, and two work in verification, validation, and accreditation of military simulation models. A number of areas and topics for research in verification, validation, and accreditation are identified. It appears that application domains of simulation models affect what topics need verification, validation, and accreditation research.

Three useful modeling techniques for specifying discrete event simulation models are discussed. Hierarchical model specification provides for model specification at different levels of abstraction. Scaling of model elements provides for the combination of similarly structured and parallel operating model elements into arrays of both fixed and dynamic sizes. Reuse of model elements allows for the repeated use of model element specifications. The Hierarchical Control Flow Graph Model paradigm is used to demonstrate the techniques discussed.
One of the key issues in designing new simulation models for parallel execution, or in the migration of existing models to parallel platforms, is the mapping of the application architecture to the parallel system arch...
