A group decision-making interface for conceptual design

The ARL Trade Space Visualizer (ATSV) is a multi-dimensional data visualization interface used in early conceptual design to support trade space exploration. Often, conceptual design teams consist of multiple decision-makers, where each team member has a unique set of requirements and preferences. Previously, the ATSV has been restricted to a single seat model, where decisionmakers explore trade spaces without any direct interaction with other ATSV design sessions. This work is focused on extending the ATSV to support a collaborative decision-making environment which consists of multiple participants, where each participant can run a unique ATSV design session. These designs sessions are linked to each other, allowing each participant to share requirements and preference structures with all other participants. Key benefits of this research include the ability to support data exploration and concurrent communication within a design session.
