Abstract

The Air Force has defined a hierarchy of models that describes the scope and level of fidelity of simulations. This 'Hierarchy of Models' begins at Level I, Engineering Analysis, and progresses to Level V, Campaign results. Separation of simulations into these levels was perfectly adequate to describe the purpose and use of a simulation and its characteristics relative to another simulation of the same system. Simulation, however, can be used to support two general types of activities: analysis and development. In analysis, we are trying to understand a system or environment so we can answer a question or test a hypothesis. The 'hierarchy of models' was developed to categorize analytical simulations. In development, we are trying synthesize a system that meets certain requirements, build the components of the system, integrate the components, and then verify that the system meets requirements. In a development effort, simulation supports: requirements analysis, functional analysis and allocation, preliminary design, detailed design, build, integrate, and test. The hierarchy of models does not provide a solid basis for establishing simulation characteristics to support a large scale development and integration effort. Other simulation characteristics are needed to be able to define the types of simulations and simulation requirements. This paper discusses these characteristics and proposes a new set of classes and characteristics.
