A model is a representation of the construction and working of some system of interest. A model is similar to but simpler than the system it represents. A simulation (see simulator types) is a method for implementing a model. There are four (4) common types of models that are used. These are: [1,2] Physical: A […]
Human-in-the-Loop (HITL) Modeling & Simulation (M&S) is a model type that requires human interaction during runtime. It employs one or more human operators in direct control of the simulation/simulator or in some key support function. Human-centered M&S is distinguished from science and process-based simulations where human intervention and modeling does not occur. [1] Human-in-the-Loop lends
Effective acquisition requires collaboration among multiple Stakeholders. Modeling & Simulation (M&S) tools combined with an information-sharing infrastructure (i.e., integrated data environment – IDE) into a distributed collaborative environment can enable cost-effective development and sustainment of systems and systems of systems. [1] M&S should share the common information base with the rest of Systems Engineering. The
Fidelity is the accuracy of the model or simulation when compared to the real world. Simulation fidelity has to do with how well the simulation responds and how the results correspond to what the simulation is trying to represent. Fidelity is important because it is what distinguishes models and simulations from other computer programs because
A High-Level Architecture (HLA) is a family of related standards that together describe a unified approach and common architecture to constructing interoperable simulation systems. It contains major functional elements, interfaces, and design rules, pertaining to all DoD simulation applications, and providing a common framework within which specific system architectures can be defined. High-Level Architecture (HLA)
The DoD Modeling & Simulation (M&S) Catalog is a web-based search capability that provides a “card catalog” level of detail about M&S tools, data and services available to its users. It’s designed to guide a user quickly to a manageable set of alternatives to evaluate. The tool has the capability to perform analysis of
The Modeling and Simulation Coordination Office (M&S CO) is a Department of Defense (DoD) organization that helps with the development, coordination, technical guidance, and standardization of Modeling and Simulation activities. It also ensures that modeling and simulation technology is consistent with other related DoD initiatives and provides administrative and technical support to the DoD M&S
The DoD VV&A Documentation Tool (DVDT) addresses the need to capture Verification, Validation & Accreditation (VV&A) information in a consistent form with consistent content. The DVDT supports the various DoD- and Service-level Communities by producing standardized VV&A documentation and meeting net-centric architecture requirements for sharing, discovering, and retrieving VV&A information within the Global Information Grid
Modeling & Simulation (M&S) requirements specify the set of capabilities that a simulation needs in order to adequately serve all of its intended uses. Users rely on information from the three domains (Problem, User and Simulation) to develop a concise and consistent set of requirements for the simulation at hand. Users use this set of
A Distributed Product Description (DPD) is a distributed collection of product-centric information that is interconnected via web technology into what appears (to the user) to be a single, combined, logically unified product representation. A DPD is a: [1] Distributed collection of digital product information A view of current product state to all program participants throughout
