PURPOSE:To search for an optimum solution by grasping the call assignment of group management elevators as a combination optimum problem, applying a TA method. CONSTITUTION:The initialization of assignment as shown by an expression is conducted. Next, initialization is conducted by giving the initial value of a threshold which plays an important role in a TA method. Next, simulation is executed in regard to the initial solution, and the value of a target function for optimumization is calculated. When waiting times in regard to respective hall calls at the initial solutions are collected, the average value of them is calculated, and it is kept as the optimum value at the present time point. Next, the change of solutions is conducted by shifting only two free hall calls assigned to different cars in regard to the preceding solution, Next, simulation is carried out in regard to this new solution, and the average value of waiting times in regard to respective hall calls is calculated. When the value of solution is improved or a worsening quantity is within a predetermined value, the average value of waiting times at the solution is made to be the optimum value. When the value of solution is worse more than the predetermined value, the change of solution is canceled. |
