OREANDA-NEWS. Mitsubishi Electric's DOAS optimizes multi-car elevator systems by allocating cars efficiently according to the floors that passengers input while waiting in the hall, helping to reduce both wait and travel times. The system also eliminates the need to press buttons upon entering the car. DOAS uses destination-control technology to maximize car allocation efficiency, including by directing passengers who are going to the same floor to use the same elevator. As a result, cars do not stop needlessly on floors being served by other cars.

The new car allocation method reduces average wait time by about 10% during congested hours, and lowers the possibility of long waits lasting 60 seconds or more during off-peak hours by about 20%. The calculations are comparisons with conventional elevator systems and are based on simulations conducted by Mitsubishi Electric using 16 floors, six cars and 20-person load capacities.

The DOAS hall panels feature upgraded design and ease of use. Big, bright 10.4-inch touch screens offer a choice of instructions in Japanese, English or Chinese. Audio guidance is optional.
