The object is to maintain the operations of a logistic system. The recovering method of the logistic system includes a plurality of controllers connected with each other via a local network. A recovery method for the logistic system comprises detecting an abnormal state of the plurality of controllers, outputting a switching requesting signal, receiving a control signal, and outputting the control signal. In outputting the switching requesting signal, when an abnormal controller that shows the abnormal state is detected, a switching requesting signal to switch from the abnormal controller to an alternate controller is outputted from the logistic system to the alternate controller. In receiving the control signal, a control signal that controls at least a part of operations of the logistic system instead of the abnormal controller is received from the alternate controller.
