原文（中国語）

[Problem] To suppress a decrease in the transport efficiency of the entire system. [Means to Solve Problem] A controllerincludes a charging instructorthat instructs to start charging each transport vehicleThe charging instructorperforms a first determination process to determine whether a charge rate of an entirety of the plurality of transport vehiclesis below a first threshold value, and instructs to start charging at least any one of the transport vehiclesif the charge rate of the entirety of the plurality of transport vehiclesis determined as being below the first threshold value. The charging instructorperforms a second determination process to determine whether the charge rate of each transport vehicleis below a second threshold value that is lower than the first threshold value, and instructs to start charging each transport vehicleif the charge rate of the transport vehicleis determined as being below the second threshold value.
