SUMMARY Uncertainty management is a particularly significant long-term foundational issue for planning, design and management of engineering systems. Its importance is far greater for engineering systems than it is in traditional engineering design. This is because engineering systems—such as automotive transport, electric power distribution, and the(More)
This paper introduces an on-going doctoral research track on the role of survivability as an attribute in the design of complex system architectures. Survivability may be defined generally as the ability of a system to minimize the impact of a finite disturbance on value delivery, achieved through either the satisfaction of a minimally acceptable level of(More)
The environment in which space systems are developed and operated can be classified as nothing less than dynamic. However, it is clear that the methods and tools relied on in conceptual design are based on static assumptions and leave little room for anything more than snapshots of the product and its environment. This paper introduces an approach to(More)
Technology transitions are essential to transforming air traffic management to meet future capacity needs. Encouraging and obtaining equipage adoption is one crucial aspect of technology transitions. We propose an approach for developing appropriate strategies to persuade aviation stakeholders to transition to new technologies. Our approach uses cost,(More)
Multi-Attribute Tradespace Exploration (MATE) for Survivability is introduced as a system analysis methodology to improve the generation and evaluation of survivable alternatives during conceptual design. MATE for Survivability applies decision theory to the parametric modeling of thousands of design alternatives across representative distributions of(More)
This paper uses an innovation theory lens to assess the potential for operationally responsive space to increase the ability of government space acquisition to meet the emerging needs of Joint Combatant Commanders. Two core challenges of generating innovation in national security space are identified: 1) enabling bottom-up initiative in a monopsony market(More)
The U.S. Air Transportation Systems faces substantial challenges in transforming to meet future demand. These challenges need to be understood and addressed in order to successfully meet future system needs. This paper uses a feedback model to describe the general system transition process and identify key issues in the dynamics of system transition, with(More)
