Group Control of Elevator by Fuzzy Multi-Purpose Decision Making

摘要

The present invention allows the multipurpose decision making to be made by determining the optimum value for satisfying all the attributes among a plurality of alternatives in order to meet the control objectives by changing the importance of the boarding call in the elevator system according to the state of the system. Provided is a group control device of an elevator by fuzzy multi-purpose decision making.;Accordingly, the present invention receives the boarding call from the boarding point calling unit 2 and the status information from the plurality of first to nth call controlling units A1 to An, and also allocates a service call according to the group control function. An input / output interface 12 for outputting an input, an input / output interface 12 for receiving a lift call and status information of a service call, and an output command for outputting an assignment command of a service call according to a group control function, and the boarding call and service Item operation means 14 for calculating the fuzzy operation value by receiving the state information of the breathing machine and assigning all the service breaths to perform the epoch operation of evaluation items according to a plurality of control purposes, and the calculated fuzzy operation value according to the state of the system. The objective evaluating means 16 for calculating fuzzy evaluation values for each purpose by mapping the objective functions for a plurality of changing control purposes, The final evaluation means 18, which calculates the fuzzy final evaluation value according to the goodness of fit for all control purposes through the defined weights, receives the weights from the manager through the monitoring means 6 and transmits the weights to the final evaluation means 18. And a ranking means 20 for determining the ranking of the calculated fuzzy final evaluation value and determining the elevator unit having the highest ranking as the service breathing unit.
