One dominating view of simulation, especially when graphical methods or notations are used to construct simulations, is that of transaction flow. This paper identifies six behavioral patterns that highlight problems with this view. An object-oriented method of constructing simulations is introduced which consists of embedding simulation entities in "yokes", which can be thought of as reified contracts.

The Generic Runtime Infrastructure for Distributed simulation (GRIDS) has been developed to investigate modularity issues in distributed simulation. It could be argued that although the HLA RTI is a widespread solution to distributed simulation, it cannot include all possible services. This paper investigates an approach to extending the distributed simulation services available in the HLA RTI. One example of this is bridging support for HLA/DIS legacy integration. This paper therefore presents GRIDS, how GRIDS can be used to provide modular service support for the HLA RTI, and a case study on legacy integration to demonstrate our approach.

The emergence of new technologies in simulation modeling such as the World Wide Web has fostered debate on the reuse of models. We present a case for model reuse and the pot of gold that it promises. We then discuss model reuse from the viewpoint of simulation modelers who use COTS simulation packages and suggest that model reuse may in fact cost more than developing new models as candidates for reuse as trust must be established through thorough testing. An alternative to this is put forward that suggests that a Grab-and-Glue, Run, Reject, Reply (G/sup 2/R/sup 3/) approach is a more appropriate use of model reuse as it emphasizes the intellectual process of problem understanding rather than model correctness as a means to itself.

This paper considers a variety of new technologies for discrete-event simulation software development. Environments and languages for Web based simulation are reviewed. Web based applications are discussed. After proposing a summary of the review, ways of working that will have an unpredictable effect on the future of simulation modeling are proposed.

The paper presents simulation modeling as a decision support technique and suggests that it can be a useful for understanding problems related to health care, randomized clinical trials in this case. The paper shows that simulation may not be regarded as a tool for deriving solutions to certain problems. In fact simulation is better suited for understanding the problem and enhancing systematic debate between the problem owners. The paper also demonstrates the usefulness of combining different software to provide a comprehensive tailor-made package (ABCSim). The example used is based on modeling a randomized clinical trial for Adjuvant Breast Cancer.

Can a PhD be of even greater benefit to a candidate than just the award of the PhD? This paper argues yes. A PhD is a process of learning by doing, during which the successful candidate discovers what being a researcher is all about, and how to write academically. The PhD dissertation is the artifact that demonstrates that the process has been undertaken successfully. It might appear that this is as much as you can expect from a PhD. Upon completion and successful defense, the intensity of focus and effort in the last stages often leaves the successful candidate almost bereft, so all consuming has this been. It would be asking too much perhaps to want more. This paper sets out to show that more should be required, not for the PhD itself, but to benefit the candidate even more. The question is how?

Health care systems are known to be quite complex in structure and operation. The technology of liver transplantation is one of the aspects of health care systems that has always been difficult to grasp. The main problem with liver transplantation is the fact that it is not easy to study using traditional quantitative tools. The paper demonstrates the use of discrete event simulation as an explorative tool to help stakeholders to understand the behavior of the system so that they can achieve informed decisions with regard to the prioritization of patients waiting for transplantation. The paper also shows the construction of a tailor-made package (LiverSim) and provides an example of how this package is used by the stakeholders to assist in the evaluation process. Some final lessons are drawn that simulation helps in exploring more issues outside the boundaries of quantitative results.
