Benefits of modeling and simulation ○ Models and simulations confirm the need for the systems and the anticipated systems behaviors before proceeding development of an actual system ○ Models and simulations present a clear, coherent design to those who will develop, test, deploy, and evolve the system, thereby maximizing productivity and minimizing error Value of modeling and simulation increases with __________________. the size of the system or SoS under development The benefit of modeling and simulation is proportional to the stakeholder's perception of the timelines, trustworthiness, and ease of use and maintenance of the model or simulation The term "model" generally refers to... an abstraction or representation of a system, entity, phenomenon, or process of interest (DoD 5000.59, 2007) The term __________ is the implementation of a model (or models) in a specific environment that allows the model's execution (or use) over time "simulation" First principle of modeling is to... clearly define the purpose of the model Some purposes of models: ○ Characterizing an existing system ○ Mission and system concept formulation and evaluation ○ System architecture design and requirements flow-down ○ Support for systems integration and verification ○ Support for training ○ Knowledge capture and system design evolution For each type of model, the appropriate _______,_______, and_________ should be determined to address the model's intended purpose breadth, depth, and fidelity In determining model scope, breadth reflects... the system requirements coverage in terms of the degree to which the model must address the functional, interface, performance, and physical requirements In determining model scope, depth indicates... the coverage of system decomposition from the system context down to the system elements In determining model scope, fidelity indicates... the level of detail the model must represent for any given part of the model For modeling and simulation what are the types of models? ○ Physical ○ Abstract ○ Informal - simple drawing tools, words; lacks precision, ambiguous ○ Formal - geometric, quantitative (mathematical), or logical Per IEEE 15288, what are the system models (modeling and simulation)? ○ Functional ○ Behavioral ○ Temporal ○ Structural ○ Mass ○ Layout ○ Network
