　ＣＰＵ１０が記憶部１１に格納されているメンテナンス支援プログラムを実行することで、図１１に示すように、点検契約抽出部１０２、メンテナンス予測部１０４、アラーム内容抽出部１０６、優先度判定部１０８、作業決定部１１０、物品手配部１１２、担当者選定部１１４、巡回ルート作成部１１６、通知部１１８、更新部１２０等が実現される。各部の処理を図１２に示すフローチャートに沿って説明する。図１２に示すフローチャートは、本実施形態に係るメンテナンス支援方法を説明するものである。 When the CPU 10 executes the maintenance support program stored in the storage unit 11, as shown in FIG. 11, the inspection contract extraction unit 102, the maintenance prediction unit 104, the alarm content extraction unit 106, the priority determination unit 108, the work A determination unit 110, an article arrangement unit 112, a person-in-charge selection unit 114, a tour route creation unit 116, a notification unit 118, an update unit 120, and the like are realized. The processing of each unit will be described with reference to the flowchart shown in FIG. The flowchart shown in FIG. 12 explains the maintenance support method according to the present embodiment.
　点検契約抽出部１０２が、契約情報ＤＢ内の契約内容を確認し、契約により予め決められている、近日中に実施すべきメンテナンス作業、及び作業を行う工場を抽出する（ステップＳ１）。 The inspection contract extraction unit 102 confirms the contract contents in the contract information DB, and extracts the maintenance work to be performed in the near future and the factory where the work is performed, which is determined in advance by the contract (step S1).
　メンテナンス予測部１０４が、運転状況ＤＢ内の運転データに基づいて、近日中に必要となるメンテナンス作業を予測する（ステップＳ２）。例えば、処理水質の変動に基づいて膜洗浄／膜交換が必要になると予測する。あるいはまた、薬品タンク内の液位の変動に基づいて、薬品補充が必要になると予測する。 The maintenance prediction unit 104 predicts maintenance work that will be required in the near future based on the operation data in the operation status DB (step S2). For example, it is predicted that membrane cleaning / membrane exchange will be required based on the quality of the treated water. Alternatively, it is predicted that chemical replenishment will be required based on fluctuations in the liquid level in the chemical tank.
　アラーム内容抽出部１０６が、アラームＤＢから、未対応のアラームの内容を抽出する（ステップＳ３）。 The alarm content extraction unit 106 extracts the content of an unsupported alarm from the alarm DB (step S3).
　優先度判定部１０８が、アラームの内容に基づいて、巡回する工場の優先度を判定する（ステップＳ４）。例えば、水処理が停止した等の重大なアラームを通知している工場の優先度が高く設定される。また、契約による定期メンテナンスを行う工場よりも緊急度や重要度の高いアラームを発している工場の優先度が高く設定されるようにすることも可能である。（この場合、警報コードに関連付けて予め緊急度や重要度を設定しておく。） The priority determination part 108 determines the priority of the factory to circulate based on the content of the alarm (step S4). For example, the priority of a factory that notifies a serious alarm such as water treatment being stopped is set high. It is also possible to set a higher priority for a factory that has issued an alarm with a higher degree of urgency or importance than a factory that performs regular maintenance by contract. (In this case, the urgency and importance are set in advance in association with the alarm code.)
　作業決定部１１０が、作業員を派遣する工場毎に、実施するメンテナンス作業を決定する（ステップＳ５）。例えば、実施するメンテナンス作業は、契約により決められているものである。また、アラームＤＢに登録されている過去のアラーム内容及びその要因から、今回対処するアラームの要因を推定し、実施する作業を決定する。 The work determination unit 110 determines the maintenance work to be performed for each factory where workers are dispatched (step S5). For example, the maintenance work to be performed is determined by a contract. Further, the factor of the alarm to be dealt with this time is estimated from the past alarm contents registered in the alarm DB and the factor thereof, and the work to be performed is determined.
　物品手配部１１２が、作業内容ＤＢを参照し、ステップＳ５で決定した作業に必要な物品を抽出、特定する（ステップＳ６）。物品手配部１１２は、物品在庫ＤＢを参照し、作業に必要な物品の在庫を確認し、搬送の手配を行う（ステップＳ７）。 The article arrangement unit 112 refers to the work content DB and extracts and specifies the articles necessary for the work determined in step S5 (step S6). The article arrangement unit 112 refers to the article inventory DB, confirms the inventory of articles necessary for the work, and arranges transportation (step S7).
　担当者選定部１１４が、作業内容ＤＢを参照し、ステップＳ５で決定した作業に必要なスキルを抽出する。担当者選定部１１４は、作業者スキルＤＢ及び作業者スケジュールＤＢを参照し、抽出したスキルを持ち、作業を行う工場が担当エリア内であり、かつスケジュールが空いている作業者を、派遣する担当者として選定する（ステップＳ８）。派遣可能な作業者が複数いる場合は、所有スキルが少ない作業者を選定してもよいし、同じ工場へ過去に行ったことがある作業者を選定してもよい。 The person-in-charge selection unit 114 refers to the work content DB and extracts skills necessary for the work determined in step S5. The person-in-charge selecting unit 114 refers to the worker skill DB and the worker schedule DB, and is responsible for dispatching workers who have the extracted skills, the factory where the work is performed is in the area in charge, and the schedule is vacant. (Step S8). When there are a plurality of workers that can be dispatched, an operator with less possession skills may be selected, or an operator who has been to the same factory in the past may be selected.
　所有スキルが少ない作業者を選定することで、経験を積ませることができる。また、所有スキルの多い作業者を残しておくことで、その後に緊急度の高いアラームが発生した場合に、当該担当者を迅速に派遣し、対応することが可能となる。 Employees can gain experience by selecting workers with less possession skills. In addition, by leaving an operator with a lot of possession skills, it becomes possible to quickly dispatch and respond to the person in charge when an alarm with a high degree of urgency occurs thereafter.
　巡回ルート作成部１１６が、作業内容ＤＢを参照し、各工場で実施する作業の標準作業時間から、各工場での作業所要時間を算出する（ステップＳ９）。 The traveling route creation unit 116 refers to the work content DB, and calculates the work required time in each factory from the standard work time of work performed in each factory (step S9).
　巡回ルート作成部１１６が、所在地情報ＤＢを参照し、各工場の所在地から、移動距離（移動時間）が最短となる訪問順を決定し、巡回ルートを作成する（ステップＳ１０）。巡回ルート作成部１１６は、ステップＳ４で判定した優先度の高い工場が優先度の低い工場よりも先になるように巡回ルートを作成する。巡回ルート作成部１１６は、道路の渋滞情報、鉄道運行情報などの交通情報をウェブ等から入手し、交通情報を考慮して、巡回ルートを作成してもよい。 The traveling route creation unit 116 refers to the location information DB, determines the order of visits in which the travel distance (travel time) is the shortest from the location of each factory, and creates a tour route (step S10). The traveling route creation unit 116 creates the traveling route so that the factory with high priority determined in step S4 comes before the factory with low priority. The traveling route creation unit 116 may obtain traffic information such as road congestion information and railway operation information from the web and the like, and may create a traveling route in consideration of the traffic information.
　通知部１１８が、巡回ルート、各工場の訪問日時、各工場での作業内容等を、作業者の端末Ｔに通知する（ステップＳ１１）。 The notification unit 118 notifies the operator's terminal T of the patrol route, the visit date and time of each factory, the work contents at each factory, and the like (step S11).
　作業完了後、作業結果が登録される（ステップＳ１２）。例えば、アラームの原因がアラームＤＢに登録される。また、作業者が新たなスキルを習得した場合、更新部１２０が作業者スキルＤＢの所有スキルを更新する。例えば、所定の研修を受講した場合や、所定の作業を所定回数実施した場合などに、新たなスキルを習得したと判定される。 After the work is completed, the work result is registered (step S12). For example, the cause of the alarm is registered in the alarm DB. Further, when the worker acquires a new skill, the update unit 120 updates the possession skill of the worker skill DB. For example, it is determined that a new skill has been acquired when a predetermined training is taken or a predetermined work is performed a predetermined number of times.
　作業結果の登録は、作業者が端末Ｔを用いて行ってもよいし、作業者が提出した報告書に基づいて、入力部１４から入力してもよい。作業者が端末Ｔを用いて登録する場合、自身が対応したアラームの原因のみ登録できる。また、所有スキルの更新は、端末Ｔからは行えないようにしてある。 The registration of the work result may be performed by the worker using the terminal T, or may be input from the input unit 14 based on the report submitted by the worker. When an operator registers using the terminal T, only the cause of the alarm that he / she can handle can be registered. In addition, the possession skill cannot be updated from the terminal T.
　このように、本実施形態に係るメンテナンス支援装置１によれば、複数の工場を効率よく巡回する巡回ルートを作成できる。また、アラーム内容等から優先度を判定して訪問順を決めるため、緊急度の高い工場でのメンテナンス作業を速やかに実施できる。 Thus, according to the maintenance support device 1 according to the present embodiment, it is possible to create a patrol route for patroling a plurality of factories efficiently. In addition, since the priority is determined from the alarm contents and the order of visit is determined, maintenance work in a factory with high urgency can be performed promptly.
　上記実施形態において、巡回ルートの作成後、水処理設備に突発的なトラブルが発生した場合、この水処理設備が設置してある工場を加えて巡回ルートが再演算され、結果が作業者の端末Ｔに通知される。 In the above embodiment, when a sudden trouble occurs in the water treatment facility after creating the circulation route, the circulation route is recalculated by adding the factory where the water treatment facility is installed, and the result is the operator's terminal. T is notified.
　なお、本発明は上記実施形態そのままに限定されるものではなく、実施段階ではその要旨を逸脱しない範囲で構成要素を変形して具体化できる。また、上記実施形態に開示されている複数の構成要素の適宜な組み合わせにより、種々の発明を形成できる。例えば、実施形態に示される全構成要素から幾つかの構成要素を削除してもよい。さらに、異なる実施形態にわたる構成要素を適宜組み合わせてもよい。 Note that the present invention is not limited to the above-described embodiment as it is, and can be embodied by modifying constituent elements without departing from the scope of the invention in the implementation stage. In addition, various inventions can be formed by appropriately combining a plurality of components disclosed in the embodiment. For example, some components may be deleted from all the components shown in the embodiment. Furthermore, constituent elements over different embodiments may be appropriately combined.
　本発明を特定の態様を用いて詳細に説明したが、本発明の意図と範囲を離れることなく様々な変更が可能であることは当業者に明らかである。
　本出願は、２０１８年３月２３日付で出願された日本特許出願２０１８－０５６４５８に基づいており、その全体が引用により援用される。 Although the present invention has been described in detail using specific embodiments, it will be apparent to those skilled in the art that various modifications can be made without departing from the spirit and scope of the invention.
