Abstract:

This report describes an expert critiquing system, the Support Environment for Design And Review SEDAR, that uses a task-based model of design for flexible control of its multi-strategy critiquing abilities. SEDAR has been developed for the flat and low-slope roofing domain, a subfield of the building design domain. It is designed to support the existing designreview protocol for roof design for the U.S. Army Corps of Engineers. SEDAR offers three critiquing strategies. The incremental error prevention strategy is intended to help users avoid errors by visually displaying off-limits areas before errors can be made. The incremental error correction strategys intent is to give immediate feedback to the user during the design process, so that the errors may he corrected before their effects are propagated to subsequent parts of the design. The hatch-processing design review strategy is intended to allow the user to conduct reviews on a design after particular roof subsystems are completed, as some errors can not be detected until this stage.
