    Abstract: The method of the present invention can be used to monitor and predict the condition of an automatic door of an elevator or more generally an automatic door in a building. In the method, the acceleration or velocity of the door is measured and a dynamic model of the door is created. Using the model, estimated values of acceleration or velocity of the door can be calculated as a function of unknown parameters. One of the unknown parameters is the frictional force acting on the door during movement. By utilizing the estimated acceleration or velocity as well as measured acceleration or velocity values, an error function is obtained, whose minimum value is found using an optimizer. The unknown parameters corresponding to the minimum value indicate the current condition of the door. On the basis of earlier measurement results, it is additionally possible to predict a point of time when a failure is likely to occur in the operation of the door. In addition to unknown force parameters, it is possible, using a genetic algorithm, to determine the operational condition of a door closing device as well.

    Abstract: PCT No. PCT/FI96/00216 Sec. 371 Date Oct. 21, 1997 Sec. 102(e) Date Oct. 21, 1997 PCT Filed Apr. 19, 1996 PCT Pub. No. WO96/33123 PCT Pub. Date Oct. 24, 1996A procedure for allocating the calls entered via landing call devices of the elevators in an elevator bank forms several allocation options. Each allocating option contains, for each active landing call, a call data item and an elevator data item which together are used to determine which elevator should service the call. The value of a cost function is calculated for each allocation option; one or more of the allocation options is repeatedly changed with respect to at least one data item, and the values of the cost functions of the new allocation options are calculated. Based on the values of the cost functions, the best allocation option is selected and the active elevator calls are allocated to the elevators in the elevator bank accordingly.
