<p>The purpose of the present invention is to maintain the operation of a logistics system (100). A recovery method for the logistics system (100) involves multiple controllers (10a, 10b, 10c, 30) that are connected to each other via a local network. The recovery method for a logistics system is provided with an abnormality detection step, a switching request step, a control signal receiving step, and a control signal output step. In the switching request step, when an abnormal controller exhibiting an abnormal state is detected, a switching request signal for switching from the abnormal controller to an alternative controller (70) is output to the alternative controller by the logistics system. In the control signal receiving step, a control signal that controls at least a portion of the operations in the logistics system (100) is received from the alternative controller (70) instead of the abnormal controller.</p> |
