摘要： An example information processing device includes first and second receiving units, a deciding unit, and first and second transmitting units. The first receiving unit receives adjustment limit information from a plurality of first external devices. The deciding unit determines adjustment rules on the basis of the adjustment limit information. The first transmitting unit transmits the adjustment rules to second and third external devices. The second receiving unit receives determination information from a fourth external device. The second transmitting unit transmits the adjustment rules to the first external devices when integrated schedule information satisfies a condition. When the integrated schedule information does not satisfy the condition, the deciding unit changes the adjustment rules. When the deciding unit has changed the adjustment rules, the first transmitting unit transmits new adjustment rules to the second and third external devices.
