Claim 2:
3. A multi device coordination control method performed by a multi device coordination control device that controls a plurality of actuator devices disposed in the same physical space, the multi device coordination control method, comprising the steps of:
acquiring prescribed information on the physical space as sensor information from one or more sensor devices disposed on the same physical space, and converting a value indicated by the acquired sensor information, to a degree of service achievement, the degree of service achievement being an indicator showing to what degree a purpose of a prescribed service realized by controlling the actuator device is achieved;
making a learning device allow an input of the degree of service achievement obtained by the conversion as an input value and making the learning device compute therefrom an actuator control amount for each of the actuator devices, to thereby obtain the actuator control amount for each of the actuator devices as an output value, the learning device being subjected to machine learning such that, upon an input of the degree of service achievement, an actuator control amount for each of the actuator devices, designed to satisfy a targeted degree of service achievement which is a target of a degree of service achievement for each service, is computed and outputted; and
converting the actuator control amount obtained as the output value to a control instruction in accordance with each of the actuator devices, and transmitting the obtained control instruction to each of the actuator devices, to thereby make the each of the actuator devices execute the control instruction,
wherein, after the control instruction is executed, sensor information is again acquired from the one or more sensor devices, and a degree of service achievement after the control of the actuator device is performed is calculated, based on a value obtained from the acquired sensor information;
wherein, if the degree of service achievement after the control is smaller than the targeted degree of service achievement, an adjustment control amount of the actuator device is calculated by applying evolution strategy algorithm using a degree of difference, the degree of difference being an indicator showing to what extent the degree of service achievement obtained this time after the control, is different from the targeted degree of service achievement, then an actuator control amount after an adjustment of interest is made is calculated, using the calculated adjustment control amount and an actuator adjustment reference amount, the actuator adjustment reference amount being a reference for adjusting an actuator control amount of this time, and, if the degree of service achievement after the control is larger than the degree of service achievement just before the control, the actuator adjustment reference amount with the actuator control amount of this time is updated; and
wherein the actuator control amount after the adjustment is converted to a control instruction in accordance with each of the actuator devices, and the control instruction is transmitted thereto, to thereby make each of the actuator devices execute the control instruction.
