Formal aspects of egress complexity

Egress complexity is concerned with the summative uncertainty experienced by a naive occupant of a building when faced with a challenge to evacuate without the assistance of signage. This paper takes the present model of egress complexity and recasts its basic initiative in terms of elementary order theory. Arguments are presented to demonstrate • istence of distinct maximum and minimum exit complexities for a given number of compartments, x02022; notonic nature of complexity and x02022; lationship of a given floorplan complexity to the corresponding measures of its homomorphic images iqueness of the theory on which the model is developed stems from a scenario-independent nonmetric approach to egress measurement.
