Based on the aforementioned performance information, identify the workers who have experience maintaining the equipment with the specified equipment ID. A maintenance support device that outputs data for displaying information indicating the identified worker.
  2. A maintenance support device according to claim 1, The aforementioned performance information indicates, for each piece of equipment in which the worker has maintenance experience, the details of any abnormalities that occurred in the equipment after the worker performed maintenance on that equipment, and the period from the time the worker performed maintenance on the equipment until the abnormality occurred. The aforementioned processor, For each worker with experience maintaining the equipment with the identified equipment ID, a maintenance evaluation is calculated based on the nature of the abnormality indicated by the performance information and the period until the abnormality occurred. A maintenance support device that outputs data for displaying information indicating which of the identified workers have a calculated maintenance evaluation of a predetermined value or higher.
  3. A maintenance support device according to claim 2, The aforementioned processor, A maintenance support device that outputs data for displaying information on workers whose calculated maintenance evaluation is equal to or greater than the predetermined value among the identified workers, and the maintenance evaluation of those workers.
  4. A maintenance support device according to claim 1, The aforementioned processor, The system outputs data for displaying an input screen that includes an area for receiving the designation of the equipment ID to be maintained, and an area for receiving input of the first threshold and the second threshold. A maintenance support device that accepts the specification of the maintenance target equipment ID and the input of the first threshold and the second threshold via the input screen.
  5. A method for supporting maintenance operations using a maintenance operation support device, The aforementioned maintenance support device includes a processor and memory, The aforementioned memory is Classification information indicating the equipment IDs of multiple devices, the industrial classification corresponding to the installation location of each of the multiple devices , and the product classification indicating the type of equipment and manufacturer associated with each of the multiple equipment IDs, The system maintains performance information indicating the equipment ID of the equipment each worker has experience maintaining, The aforementioned maintenance support method is The processor determines, for each pair of device IDs of the devices included in the plurality of devices, the first similarity of the industry classification corresponding to each device ID of the device ID pair, and the second similarity of the product classification corresponding to each device ID of the device ID pair. The processor receives a designation of a device ID for a device to be maintained, which is the device ID of a device to be maintained included in the plurality of devices. The processor refers to the performance information to determine whether there is an operator with experience in maintaining the equipment with the equipment ID to be maintained. If the processor determines that there is an operator with experience in maintaining the equipment with the equipment ID, it outputs data to display the operator with experience in maintaining the equipment with the equipment ID. If the processor determines that there are no workers with experience in maintaining the equipment with the equipment ID to be maintained, The processor identifies an equipment ID whose first similarity to the equipment ID to be maintained is equal to or greater than the first threshold, and whose second similarity to the equipment ID to be maintained is equal to or greater than the second threshold. The processor identifies, from the performance information, an operator who has experience maintaining the equipment with the identified equipment ID. A maintenance support method comprising the processor outputting data for displaying information indicating the identified worker.

Description

This invention relates to a maintenance support device and a maintenance support method. As background technology for this field, there is Japanese Patent Publication No. 2016-148882 (Patent Document 1). This publication states: "The in-work biometric information collection unit obtains in-work biometric information by collecting biometric information at each stage of work. The work history storage unit stores work IDs, work type IDs, and worker IDs. The biometric information storage unit stores in-work biometric information and work IDs. The input unit receives work type IDs for tasks that are yet to be performed. The job suitability calculation unit extracts those associated with the work type IDs received by the input unit in the work history storage unit, extracts in-work biometric information for each extracted work ID, and calculates the job suitability for each extracted worker ID based on the extracted in-work biometric information, corresponding to the work type classified by the work type ID received by the input unit."
