During Hong Kong's Elevcon '95, a paper was presented that brought the term "dynamic zoning" to the world. "Dynamic zoning" was an improved version of the "channelling" technique developed almost a decade ago. In volume 1 of the International Journal of Elevator Engineering, that paper on dynamic zoning was further elaborated, with more details included. However, until recently, the consideration has been only with up-peak and down-peak conditions. In this paper, the concept of dynamic zoning has been extended to include random interfloor traffic conditions as well, while up-peak and down peak become special cases. The most general traffic condition - of interfloor traffic with unequal floor demand and population - is employed to arrive at an appropriate "equivalent roundtrip time" for each car with an assigned zone. A cost function based on the optimal equivalent roundtrip time of all cars is used to select the best zoning using a genetic algorithm due to its high speed of convergence. Hence, the name "comprehensive" is adopted.
