simulation is characterized by the need to run multiple sets of computationally intensive experiments. We argue that grid computing can reduce the overall execution time of such experiments by tapping into the typically underutilized network of departmental desktop PCs, collectively known as desktop grids. Commercial-off-the-shelf simulation packages (CSPs) are used in industry to simulate models. To investigate if grid computing can benefit simulation, this paper introduces our desktop grid, WinGrid, and discusses how this can be used to support the processing needs of CSPs. Results indicate a linear speed up and that grid computing does indeed hold promise for simulation

The UK National Blood Service (NBS) is a public funded body that is responsible for distributing blood and associated products. A discrete-event simulation of the NBS supply chain in the Southampton area has been built using the commercial off-the-shelf simulation package (CSP) Simul8. This models the relationship in the health care supply chain between the NBS processing, testing and issuing (PTI) facility and its associated hospitals. However, as the number of hospitals increase simulation run time becomes inconveniently large. Using distributed simulation to try to solve this problem, researchers have used techniques informed by SISO's CSPI PDG to create a version of Simul8 compatible with the high level architecture (HLA). The NBS supply chain model was subsequently divided into several sub-models, each running in its own copy of SimulS. Experimentation shows that this distributed version performs better than its standalone, conventional counterpart as the number of hospitals increases

For many years discrete-event simulation has been used to analyze production and logistics problems in manufacturing and defense. In the early 1980s, visual interactive modelling environments were created that supported the development, experimentation and visualization of simulation models. Today these environments are termed commercial-off-the-shelf simulation packages (CSPs). With the advent of distributed simulation and, later, the high level architecture, the possibility existed to link together these CSPs and their models to simulate larger problems within enterprises (e.g. multiple production lines) and across supply chains. However, the problem of standardizing the use of the HLA and its constituent parts in this domain exists. The solution of this problem is the work of the CSP interoperability product development group (CSPI PDG). The purpose of this paper is to introduce the CSPI PDG and to review the suite of standards proposed by the group and current progress

How do we consider problems and models in the practice of simulation? It is our possibly contentious observation that simulation model solving seems to be more critical to the mission of simulation modeling than problem solving. Inspired by the theme of this year's Winter simulation Conference, we ask the question, "Is problem solving, or simulation model solving, mission critical?" To investigate this we look at three perspectives, those of the textbook, the article and the editorial. The textbook perspective is the balance of the "traditional" view of simulation presented by the academic textbook against practical experience. The article perspective is a classification of papers published in four leading simulation journals in the year 2004 (ACM TOMACS, simulation, simulationmodelling Practice and Theory, and simulation & Gaming). The editorial perspective is a discussion of editorial policy presented by the same journals. Our findings show that our observation is not contradicted.

simulation modellers are major users of software tools. Advances in computing such as collaborative working tools and distributed technologies have created new possibilities for innovation in simulationmodelling. Collectively, we address these as Collaborative Support for simulationmodelling (CSSM). To contribute to CSSM, we consider the problem of whether or not it is possible to support human-to-human collaboration in simulationmodelling through the use of commonly available groupware technology. The paper reviews aspects of human-to-human collaboration in the simulationmodelling process and introduces an example of commonly available groupware technology, the net-conferencing groupware tool NetMeeting®. Results of a survey into the perceived use of NetMeeting® in simulation and some resulting applications of the net-conferencing tool that have emerged are presented.

This article describes the results of one of the ten pilot programmes under the integrated manufacturing and service systems (IMSS) initiative pursued by the Agency for Science, Technology and Research (A* STAR) in Singapore. The objective of this particular programme is to investigate how design, analysis, enhancement and implementation of critical business processes in a manufacturing and service network can be realised using one single simulation/application framework. The overall architecture of the framework outlines how commercial simulation packages and Web-service based business process application components would have to be connected through a commercial application framework to achieve maximum leverage and re-usability of the applications involved. In the pilot phase of this programme, research issues were also addressed with regard to mechanisms for interoperation between commercial simulation packages, symbiotic interaction between simulation-based decision support components and physical systems, and simulation speed-up through multi-objective optimal computing budget allocation techniques on a grid infrastructure.
