To improve the efficiency and effectiveness of designing signage systems in buildings, we
present AUTOSIGN–a design tool that supports user-in-the-loop and multi-criteria
optimization of signage layouts in complex buildings. We formulate signage placement as a
multi-objective optimization problem with competing objectives (ie, total distance travelled,
total number of turns, the centrality of decision points, path overlap, and number of decision
taken) and constraints (ie, user-specified sign location and orientation threshold), which we …
