Ontologies to Support Repeatable and Valid Customer Requirements Generation

Creator:

Lemke, Mark T.

Abstract:

Due to the growing complexity, sophistication, and interconnectedness of present day engineered products and services, the use of ontologies in engineering design is becoming more widespread. An ontology provides a standardized way of describing concepts in a domain of interest and the relationships between these concepts to better understand the...

Masters Thesis
Enabling safety-informed design decision making through simulation, reasoning and analysis

Creator:

Jensen, David Charles

Abstract:

While many organizations claim to "put safety first," safety is rarely considered early in the design process when system-level architectural decisions are made. Instead, system design follows an abstraction-to-detail process to first meet functional and then performance requirements. Following this process, safety assurance occurs in the later stages of design...

A framework for assessing and improving the resilience of complex engineered systems during the early design process

Creator:

Mehrpouyan, Hoda

Abstract:

As modern systems continue to increase in size and complexity, they pose significant safety and risk management challenges. System engineers and much of the government research efforts are focused on understanding the attributes and characteristics that emerge from the interactions of components and subsystems. As a result, the objective of...
