Abstract
The vision of achieving digital engineering in the
US Department of Defense has instigated work on defining
the information content and structure of the system model.
However, few seem to have asked what are the requirements
for the system model? In this paper, we use a requirements
process to elicit and define the requirements for the system
model. The system model is a digital artifact containing
descriptions of all the essential objects, their properties, and
the relationships between them for the system-of-interest (SoI).
The paper describes the context of the system model in
relationships to the other components of model-based systems
engineering (MBSE) consisting of a modeling language, schema,
model-based process, presentation framework, MBSE tools,
and knowledgeable workforce. The paper describes how these
components interact to provide effective MBSE. Requirements
are stated for each component. The paper additionally derives
information requirements for the system model according to the
systems engineering process’s information needs by examining
the inputs and outputs of each activity in the systems engineering
process. Lastly, the paper derives the quality characteristics
for the system model from the literature on ontologies, modeling
languages, and semiotics. The result is a set of requirements
for the system model to support MBSE and the digital thread.
