PhD defence by Peter Gade

PhD defence by Peter Gade

Peter will present and defend his thesis "Ecological BIM-based Model Checking".


28.08.2020 kl. 09.00 - 13.00


This thesis presents a novel approach to develop BIM-based Model Checking (BMC) systems named Ecological BMC. BMC is a method that makes use of BIM-models to automate a checking process of, e.g., sustainability or building codes rules. Such a method can potentially yield significant results by improving the speed, consistency, and precision of the checking process and
results. However, BMC systems have been challenging to develop and use by practitioners due to socio-technical challenges. Attempting to improve BMCsystem's development, the practitioner's context was investigated through various inquiries to understand better the socio-technical factors relevant to BMC systems use. The findings from the inquiries were used to develop
prototypes that were tested with practitioners to evaluate their performance.

The insights of the inquiry, prototype development, and evaluation were used to suggest improvements to the practical applicability of BMC systems based on ecological rational perspectives on BMC systems development. An ecological
rational perspective means that rationality is not derived deterministically, but more from an ecology, i.e., context of the rationale. To ensure an Ecological BMC-system, it must be situated in the business; its rules formulations based on heuristics; emphasize rules transparency and flexibility, and provide performance tracking.


Please send an email to Linda V. Andersen no later than 26 August 2020 and you will get an invitation for the event or a copy of thesis if requested.
