A maintenance contractor who has received an evaluation may be selected, or a maintenance contractor with a high average value of evaluations from all customers may be selected.

  Alternatively, a maintenance contractor having the (most) type of work registered in the skill information may be selected. For example, as a result of actually inspecting the water treatment facility 2, a work different from the work specified by the work specifying unit 102 may be required. In that case, if the maintenance contractor has a lot of work that can be handled, it can be dealt with promptly.

  The distribution unit 110 distributes data necessary for the maintenance work to the maintenance contractor selected by the contractor selection unit 108. Data necessary for the maintenance work is, for example, the above-described customer information, work information of work to be performed, and the like. The work information includes a work procedure corresponding to each work item, and the work procedure is specified based on the work information.

  The work result receiving unit 112 receives a work result (work report) from the maintenance company that performed the work. For example, the work result includes information such as a problem that has occurred in the water treatment facility 2. The usage history data is updated based on this information. The management device 1 accumulates and learns this information, and the work specifying unit 102 improves the work specifying accuracy.

  The work result receiving unit 112 receives an evaluation result for the maintenance work from the customer. Based on the evaluation result, the evaluation information of the maintenance company information is updated.

  When a maintenance company performs a designated skill-up certification action, such as taking a course or passing a certification examination, it submits a certificate such as a course completion certificate or a copy of a certification certificate to the administrator. The operator of the management center uses the input unit 14 to input information such as a lecture that has been taken and a test that has passed.

  The update unit 114 determines the skills newly acquired by the maintenance company (operations that can be dealt with) from the training and test information input via the input unit 14, and uses the maintenance company information of the maintenance company. Update skill information and outsourced field information included.

  Next, an example of a method for selecting a maintenance company will be described. For example, it is assumed that an alarm is generated from the water treatment facility 2 installed in a factory of a customer A that the differential pressure of the RO membrane exceeds a threshold value. The operation specifying unit 102 of the management device 1 has similar to the increasing tendency of the differential pressure at that time, based on the usage history data, in this RO membrane device, the organic matter has adhered to the past and the membrane cleaning has been performed. judge. Moreover, the work identification unit 102 confirms that the water to be treated contains a large amount of organic matter. The operation specifying unit 102 determines that there is a high possibility of the membrane being clogged with an organic substance, and specifies the operation to be performed as membrane cleaning with alkali.

  The candidate extraction unit 104 refers to the skill information of the maintenance contractor information of each maintenance contractor, and extracts a maintenance contractor candidate who performs the film cleaning. The inquiry processing unit 106 notifies the extracted candidate maintenance company of the work content, the desired work date, and the like, and inquires whether the work can be performed and the cost estimate of the work.

  The contractor selection unit 108 selects a maintenance contractor who requests work based on the response content from the maintenance contractor. For example, the contractor selection unit 108 selects a maintenance contractor with the earliest work schedule or a maintenance contractor who has work experience in the factory of the customer A.
