1. An elevator group management system that decides any of a plurality of cars as an assigned car in response to a newly generated hall call, comprising:

  • waiting time evaluation index computing means computing a waiting time evaluation index based on an estimated arrival time at a loading floor by the hall call for each of said plurality of cars in a first case before an assignment is made as said assigned car and a second case after an assignment is made as said assigned car, and outputting waiting time evaluation index information in which said waiting time evaluation index is specified;

    an in-travel power consumption computing section computing an in-travel power consumption value in a travel-expected section from a current position to a last stop position for each of said plurality of cars in each of said first and second cases, and outputting in-travel power consumption value information in which said in-travel power consumption value is specified, said travel-expected section being expected to be covered by a known call for each car;

    an in-future-travel power consumption computing section computing an in-future-travel power consumption value in a predetermined future travel-expected section following the last stop position of the travel-expected section expected to be covered by each car for each of said plurality of cars in each of said first and second cases, and outputting in-future-travel power consumption value information in which said in-future-travel power consumption value is specified; and

    an assigned car deciding section computing, based on said waiting time evaluation index information, in-travel power consumption value information and in-future-travel power consumption value information, an assigned total evaluation index before assignment and an assigned total evaluation index after assignment for each of said plurality of cars in said first and second cases and deciding, as said assigned car, a car with the smallest value of the assigned total evaluation index after assignment with respect to the assigned total evaluation index before assignment.
