The decisions made in this phase, covering performance budgets, structural concepts, and propulsion configurations, are rarely substantially revised thereafter, yet the processes that govern them provide no structured means of revisiting them coherently as requirements, assumptions, and knowledge continue to evolve. A review of the literature reveals that, despite mature processes for feasibility assessment and requirements management, early-stage aerospace design lacks a systematic means of exploring, justifying, and revisiting design decisions as the knowledge that governs them continues to evolve. To address these, this thesis proposes a methodology centered on the concept of \u0022system intent\u0022, the formally encoded combination of prioritized requirements, decision rationale, explicit assumptions, and tacit knowledge, and its systematic connection to multidisciplinary trade-space exploration and decision justification. The methodology is developed across three successive research areas and evaluated through a multi-domain, commercial-aircraft conceptual design demonstration that involves sequential changes to requirements and assumptions. The result is a pipeline that equips designers to formally encode the reasoning behind design decisions in a way that actively drives trade-study formulation, to respond to requirement and assumption changes through targeted updates rather than complete reconstruction, and to assess, at any point in the conceptual phase, which assumptions most threaten the stability of the current design selection and what would need to change for an alternative decision to be warranted, capabilities that current practice does not support. This work provides a structured foundation for design decision-making in complex aerospace programs where requirements, priorities, and knowledge are subject to continuous revision.\u003Cbr\u003E\u003Cbr\u003EDate and time: 2026-04-23, 8AM - 11AM\u003Cbr\u003E\u003Cbr\u003ELocation: Collaborative Design Environment (CoVE), Weber (SST II)\u003Cbr\u003E\u003Cbr\u003ECommittee:\u003Cbr\u003EDr. Dimitri Mavris (advisor), School of Aerospace Engineering\u003Cbr\u003EProf. Daniel Schrage, School of Aerospace Engineering\u003Cbr\u003EProf. Kai James (Pending), School of Aerospace Engineering\u003Cbr\u003EDr. Elena Garcia, School of Aerospace Engineering\u003Cbr\u003EDr. Jorge Camacho-Casero, Airbus\u003Cbr\u003E,\u0026nbsp;\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E","summary":"","format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003EIntent-Conditioned Trade-Space Exploration and Decision Support for Early-Stage Aerospace System Design\u003C\/p\u003E","format":"limited_html"}],"field_summary_sentence":[{"value":"Intent-Conditioned Trade-Space Exploration and Decision Support for Early-Stage Aerospace System Design"}],"uid":"27707","created_gmt":"2026-04-07 20:41:02","changed_gmt":"2026-04-07 20:41:36","author":"Tatianna Richardson","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2026-04-23T08:00:00-04:00","event_time_end":"2026-04-23T11:00:00-04:00","event_time_end_last":"2026-04-23T11:00:00-04:00","gmt_time_start":"2026-04-23 12:00:00","gmt_time_end":"2026-04-23 15:00:00","gmt_time_end_last":"2026-04-23 15:00:00","rrule":null,"timezone":"America\/New_York"},"location":"Collaborative Design Environment (CoVE), Weber (SST II)","extras":[],"groups":[{"id":"221981","name":"Graduate Studies"}],"categories":[],"keywords":[{"id":"102851","name":"Phd proposal"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1788","name":"Other\/Miscellaneous"}],"invited_audience":[{"id":"78771","name":"Public"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}}}
