Order distribution method and device
The invention provides an order distribution method and device, and relates to the field of order distribution. The order distribution method firstly acquires the distribution information and the order distribution amount of the target order, and then, according to the order information of the target order and the association degree of the historical distribution of the rider, calculates the accepting the order probability of the target order under the order distribution amount of the candidate rider in the target order as a constraint condition and finally determines the push object accordingto the joint probability. Since the historical rider distribution reflects the preference of the candidate rider for certain orders, the preference degree of the candidate rider on the target order by means of the historical rider distribution (the preference degree is represented by the accepting the order probability) can be deduced, after the preference degree of the candidate rider on the target order is determined, the target order can be pushed to the rider with more interest in the target order, and the order distribution amount can be controlled to a certain extent, and the order probability of the rider can be improved.
