Control method, control device, and non-transitory computer readable storage medium

A control device that controls a plurality of moving objects that convey a plurality of cargos, the control device comprising:

• a processor;
• and
• a memory including a control program that, when executed by the processor, causes the processor to:
• acquire a residual battery capacity of the plurality of moving objects;
• determine a target residual battery capacity of the plurality of moving objects in a next unit of time;
• allocate a conveyance unit to each of the plurality of moving objects based on the residual battery capacity and the target residual battery capacity of each of the plurality of moving objects and a weight of each of the plurality of cargos;
• and
• transmit, to each of the plurality of moving objects, control information instructing a conveyance work of the conveyance unit allocated to each of the plurality of moving objects, wherein
• when the processor determines the target residual battery capacity:
• the target residual battery capacity is determined with a number of moving objects to be charged in the next unit of time being less than or equal to an upper limit number of moving objects that are simultaneously chargeable by a charging device;
• the plurality of moving objects is divided into a plurality of groups having the upper limit number of moving objects or less;
• a charging timing of moving objects in an arbitrary k-th group among the plurality of groups is set to be after k units of time;
• and
• the target residual battery capacity of the moving objects in the arbitrary k-th group in the next unit of time is determined with the residual battery capacity of the moving objects in the arbitrary k-th group after the k units of time being a predetermined charge start residual battery capacity.

A non-transitory computer readable storage medium storing a program that causes a computer of a control device, that controls a plurality of moving objects that conveys a plurality of cargos, to:

• acquire a residual battery capacity of the plurality of moving objects;
• determine a target residual battery capacity of the plurality of moving objects in a next unit of time;
• allocate a conveyance unit to each of the plurality of moving objects based on the residual battery capacity and the target residual battery capacity of each of the plurality of moving objects and a weight of each of the plurality of cargos;
• and
• transmit, to each of the plurality of moving objects, control information instructing a conveyance work of the conveyance unit allocated to each of the plurality of moving objects, wherein
• when the computer determines the target residual battery capacity:
• the target residual battery capacity is determined with a number of moving objects to be charged in the next unit of time being less than or equal to an upper limit number of moving objects that are simultaneously chargeable by a charging device;
• the plurality of moving objects is divided into a plurality of groups having the upper limit number of moving objects or less;
• a charging timing of moving objects in an arbitrary k-th group among the plurality of groups is set to be after k units of time;
• and
• the target residual battery capacity of the moving objects in the arbitrary k-th group in the next unit of time is determined with the residual battery capacity of the moving objects in the arbitrary k-th group after the k units of time being a predetermined charge start residual battery capacity.
