METHOD AND DEVICE FOR INSTANT ASIGNMENT TO DESTINATION CALL FOR ELEVATOR GROUP, BASED ON OPERATION COAST AND VARIABLE PLUS/MINUS POINT FACTOR

摘要

PURPOSE: To definitively and immediately allocate target calls to the individual elevators according to higher rank and lower rank function requirements and display these allocations at the call input floors immediately. CONSTITUTION: A target call is immediately allocated to the individual elevators by target call allocation algorithms in one higher rank. Cost computation algorithms in one lower rank computes operation costs equivalent to passenger's wait time and other loss time formed as a sum of many parts of partial operation costs based on elevator data related to each elevator and each target call. After that, they are compared per each operation cost or each target call of all elevators to allocate an elevator having the minimum operating cost immediately and finally with respect to the target call, thereby improving passenger's wait time and time for reaching a target story.
