The present invention relates to a method and apparatus for estimating the probability of occurrence of an elevator crew call, comprising: a hall calling number storage unit for recording the number of hall calls generated for a predetermined time in a layered manner; Number of calls to be recorded on a line by line basis Number of calls to be saved Number of calls to be saved and number of new calls to be registered by line Number of calls to new calls Number of lines to be called on the basis of data received from the store The probabilistic predicting unit learns the probability of occurrence of the breath call by each line and learns the data obtained by learning with the already stored data and stores the optimum data, and responds to the breath call based on the probability prediction unit and the learning unit By estimating the expected time of arrival of the expiration or the prediction of the load within the expiration, It contributes to the efficient allocation.
