System models and model-based engineering methods have the promise of transforming the way that industrial engineers interact with production and logistics
Ontology has many applications to engineering but is not easily taken up by engineers. For example, specifying products in space and time together (four
Designing complex systems often requires engineers from multiple disciplines (mechanical, electrical, production, and so on) to communicate with each other and
Integrating finite element analysis (FEA) with systems engineering (SE) would improve traceability, consistency, and interoperability between SE and FEA
This paper reviews and classifies literature on operational control of discrete event logistics systems (DELS). Operational control manipulates the flow of
Analysis models, such as discrete event simulation models, are used to support design and operation of discrete event logistics systems (DELS). The time and

Manufacturing standards provide the means for industries to effectively and consistently deploy methodologies and technologies to assess process performance
Many engineering disciplines that interact with systems engineering use simulation tools to build models based on nist-equations, which are solved to predict
It is increasingly common for language specifications to separate visual forms (concrete syntax) from underlying concepts (abstract syntax), enabling languages
Engineering and enterprise processes overlap in their concerns, for example, coordinating product design and customer relations. Integration of these processes

An important aspect of systems and products is how they interact with their environment, including how they are operated. Behaviors external to systems usually
This paper describes new capabilities in the Systems Modeling Language that reduce the complexity of specifying systems through componentization, and increase
A significant cost of manufactured systems arises in changing system specifications after they have been built and delivered to customers. This might be due to
Computer-interpretable representations of system structure and behavior are at the center of designing todays complex systems. Engineers create and review such
