Claim Text:
1. An operations management method in a system including an operations management device having a processor and a memory device, a plurality of devices which consume electric power or energy, and a plurality of facilities for supplying power to and/or for cooling of the devices, the operations management method comprising the steps of: acquiring, by the operations management device, locations of the devices, locations of the facilities, and environmental information of the facilities; obtaining, by the operations management device, a plurality of combinations of allocations of workloads to be executed by the devices based on the locations of the devices; calculating, by the operations management device, power consumptions of the respective devices with regard to each of the plurality of combinations of allocations of workloads to be executed by the devices based on a function or a numerical table of the power consumptions of the respective devices with regard to amounts of workloads to be executed by the respective devices; calculating, by the operations management device, power consumptions of the facilities necessary for each of the combinations based on the power consumptions of the respective devices, the locations of the devices, the locations of the facilities, and the environmental information of the facilities; selecting, by the operations management device, one of the combinations of allocations of workloads based on a solution of a combinational optimization problem, which minimizes the power consumption of the system, including the calculated power consumptions of the respective devices, calculated in the step of calculating power consumptions of the respective devices, and the calculated power consumption of the facilities, calculated in the step of calculating power consumption of the facilities; and allocating, by the operations management device, the workloads to the devices according to the one selected combination of allocations of workloads.
