This thesis studies the problem of data link in the NAT under a technology transition framework of value creation, capture, and delivery. Creating value through a new technology, such as data link, refers to designing competitive value propositions for stakeholders. Capturing value means recovering an investment in a technology through the value it creates.(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)

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 ongoing 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)

Fractionated spacecraft consist of physically independent, " free-flying " modules composed of various subsystems. Thus, a fractionated spacecraft might consist of one module responsible for power generation and storage, another module responsible for communications, another module responsible for the payload, and so on. Fractionated spacecraft are 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)
