Tailorable Tradespace Analysis of Mobility and Survivability for Ground Vehicles (TTAMS-GV)
Abstract
The Perduco Group has developed a framework (TTAMS-GV) for conceptualizing, at different levels of automation, the design of ground vehicles: providing guidance to analysts and engineers regarding how a tradespace should be created and explored in order to best gain insights about the tradeoffs between key performance attributes such as mobility and survivability. The automation controls considered in this Phase I project were the use of aggregation (how should attributes be combined into value?) and prescription (how should data be filtered to emphasize good alternative designs?). The different possible choices for both of these types of automation result in a wide range of potential tradespace formulations which represent tradeoffs between human and computational exploration enable, which is dependent on the case, the human users, and the available computational resources. The net recommendations of these indicator metrics can be used to improve the quality of an analysis effort by adjusting automation in a beneficial way, best leveraging the complementary strengths and weaknesses of human and computer. TTAMS-GV was demonstrated on a proxy ground vehicle model in order to illustrate the differences in the types of available insights when conducted at different levels of automation. TTAMS-GV can assist the practitioner in finding the amount of automation that best supports their analysts while still leveraging their human insight.effort. Indicator metrics of two levels of severity (notification/warning) were also developed to assess these different formulations for the quality of analysis they
