Matthew E Brand, Daniel N Nikovski: Method and system for controlling an elevator system. Mitsubishi Electric Research Laboratories, Andrew Curtin, Dirk Brinkman, January 6, 2004: US06672431 (21 worldwide citation)

A method controls an elevator system including multiple elevator cars and multiple floors. A new passenger at one of the floors signals a hall call. In response to receiving the hall call, the method determines, for each car, a set of all possible future states of the elevator system. The future sta ...

Daniel N Nikovski, Matthew E Brand: Method and system for scheduling cars in elevator systems considering existing and future passengers. Mitsubishi Electric Research Laboratories, Dirk Brinkman, Andrew J Curtin, March 21, 2006: US07014015 (8 worldwide citation)

A method schedules cars of an elevator system in a building. The method begins execution whenever a newly arrived passenger presses an up or down button to generate a call for service. For each car, determine a first waiting time for all existing passengers if the car is assigned to service the call ...

Matthew E Brand, Daniel N Nikovski: Optimal parking of free cars in elevator group control. Mitsubishi Electric Research Laboratories, Dirk Brinkman, Andrew J Curtin, October 26, 2004: US06808049 (6 worldwide citation)

A method controls the distribution of free cars in an elevator system. First, the number of free cars in the elevator system are counted whenever this number changes. At the same time, the arrival/destination rates of passengers at each of the floor is determined. The rates are used to identify up-p ...

Daniel N Nikovski, Matthew E Brand, Dietmar Ebner: System and method for scheduling elevator cars using branch-and-bound. Mitsubishi Electric Research Laboratories, Dirk Brinkman, Gene V Vinokur, February 3, 2009: US07484597 (5 worldwide citation)

A method schedules cars of an elevator system. Each possible assignment of a set of hall calls to a set of cars is represented by a solution vector maintained as a node in a search tree. Each solution vector is evaluated using an ESA-DP process according to an immediate policy to determine initially ...

Daniel N Nikovski, Matthew E Brand, Dietmar Ebner: System and method for scheduling elevator cars using pairwise delay minimization. Mitsubishi Electric Research Laboratories, Dirk Brinkman, Gene Vinokur, June 16, 2009: US07546905 (2 worldwide citation)

A method schedules cars of an elevator system, the elevator system including a set of cars, and a set of hall calls. For each car, a waiting time is determined independently if the hall call is the only hall call assigned to the car. For each car, a mutual delay ΔW(h|g) is determined for each possib ...
