Assessing Lifecycle Value Using Object-Based Modeling by Incorporating Excess and Changeability


By: D. Long n & S. Ferguson n

author keywords: design for X; life cycle analysis and design; product design; systems engineering
TL;DR: The approach borrows from Decision-Based Design and Model Based System Engineering in creating a generic modeling method capable of excess valuation that holistically assesses the value of excess by evaluating both its costs and benefits. (via Semantic Scholar)

Toward Quantifiable Evidence of Excess' Value Using Personal Gaming Desktops

Long, D., Morkos, B., & Ferguson, S. (2021, March 1). JOURNAL OF MECHANICAL DESIGN, Vol. 143.

By: D. Long n, B. Morkos* & S. Ferguson n

author keywords: excess; value; requirements modeling; uncertainty; technology forecasting; design evaluation; systems design
TL;DR: The argument that engineers (and end-users) should embrace strategic inefficiencies—even though they might never be used—is strengthened, and evidence is provided that excess can improve end-user system value when future requirements are unknown. (via Semantic Scholar)

Studying Dynamic Change Probabilities and Their Role in Change Propagation


By: D. Long n & S. Ferguson n

author keywords: excess; changeability?; design theory and methodology; systems design
TL;DR: Results show that excess placement in specific components, and the presence of system hubs (high-degree components), can mitigate the impact of excess consumption when multiple system modifications are made over time. (via Semantic Scholar)

2017 conference paper

A case study of evolvability and excess on the B-52 stratofortress and FA-18 hornet

Proceedings of the asme international design engineering technical conferences and computers and information in engineering conference, 2017, vol 4.

By: D. Long n & S. Ferguson n

TL;DR: The United States Air Force (USAF) B-52 Stratofortress and the United States Navy (USN) F/A-18 Hornet are evaluated to characterize the changes in desired capabilities and what system attributes allowed them to either successfully adapt or prevented them from adapting to enhance system lifetime value.
