Modeling and Simulation (M&S) is the use of models, including emulators, prototypes, simulators, and stimulators, either statically or over time, to develop data as a basis for making managerial or technical decisions. The terms “modeling” and “simulation” are often used interchangeably. [2]
M&S is a tool used in systems engineering to gather information to make decisions. It’s normally used in acquisitions to help define requirements and for testing or analyzing a system or process. M&S will utilize emulators, Prototypes, simulators, and stimulators to develop data for systems engineers. It’s used mostly during the Technology Development (TD) Phase of the Acquisition Process.

Modeling is the process of producing a model; 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. One purpose of a model is to enable the analyst to predict the effect of changes to the system. [3]
A simulation of a system is the operation of a model of the system. The model can be reconfigured and experimented with; usually, this is impossible, too expensive or impractical to do in the system it represents. [3]
M&S is intended to provide readily available, operationally valid environments approved by warfighters to explore concepts and refine capability requirements in preparation for field experimentation. M&S tools are used that accurately capture current and future Joint and Service capabilities, doctrine, and tactics. [1]
DoD 5000.59 “DoD Modeling and Simulation (M&S) Management”, establishes M&S policy including ensuring that M&S investments promote the enhancements of DoD M&S technologies in support of operational needs and the acquisition process; develop common tools, methodologies, and databases; and establish standards and protocols promoting the internet, data exchange, open system architecture, and software reusability of M&S applications. This policy also establishes and defined the roles of the DoD M&S Coordination Office (MSCO). [1]
