Reuse has been very difficult or in some cases impossible in the Modeling and Simulation (M&S) discipline. This paper focuses on how reuse can be accomplished by using a conceptual model (CM) in a community of interest (COI). We address the issue of reuse in a multifaceted manner covering many areas (types) of M&S such as discrete, continuous, Monte Carlo, system dynamics, gamingbased, and agent-based. M&S is commonly employed and reuse is critically needed by many COIs such as air traffic control, automobile manufacturing, ballistic missile defense, business process reengineering, emergency response management, military training, network-centric operations and warfare, supply chain management, telecommunications, and transportation. We present how a CM developed for a COI can assist in reuse for the design of any type of large-scale complex M&S application in that COI. A CM becomes an asset for a COI and offers significant economic benefits through its effective reuse.
Conducting large-scale complex modeling and simulation (M&S) projects continues to pose significant challenges for M&S engineers, project managers, and sponsoring organizations. This advanced tutorial presents an M&S life cycle to alleviate the challenges. The M&S life cycle describes a framework for organization of the processes, work products, quality assurance activities, and project management activities required to develop, use, maintain, and reuse an M&S application from birth to retirement. It provides guidance to an M&S developer (engineer), manager, organization, and community of interest. The M&S life cycle specifies the work products to be created by executing the corresponding processes together with the integrated verification, validation and quality assurance activities. The M&S life cycle is critically needed to modularize and structure a large-scale M&S application development, and to provide valuable guidance for conducting an M&S project successfully.
Although Modeling and Simulation is successfully applied for several decades, the community only established a handful of M&S specific standards. Although the standards were applied enabling worldwide distributed simulation applications, in particular in the training application domain of military simulation systems, the general success of M&S standard efforts and their potential for general applicability has been debated repeatedly during several conferences and workshop. This collection of position statements discusses related questions, such as, "What makes M&S special that we need M&S standards," "Are M&S standards truly different from Software Engineering Standards," and "What metrics can be used to measure M&S standard success," and tries to contribute to establishing a methodological approach to identify 2975 978-1-4577-2109-0/11/$26.00 ©2011 IEEE
