Abstract
Description
本実施形態にかかる保全計画策定支援システムは、生産用機械等の産業用機械の保全計画の策定を支援するためのシステムである。
本実施の形態において、保全計画策定支援システムは、1台のサーバで実現されている。図1は、そのサーバおよび接続先の構成を示す模式図である。サーバ1は、データベース2にアクセス可能である。なお、データベース2は、サーバ1の内部に設けられてもよいし、サーバ1の外部に設けられ、通信ネットワークを介してアクセスされてもよい。
図3は、データベース2の例を示す図である。データベース2は、顧客別「納入設備機械情報」管理DB21、納入設備機械別「ユニット構成情報」管理DB22、ユニット別「主要部位情報」マスター管理DB23、ユニット/主要部位別「点検箇所情報」マスター管理DB24、点検箇所別「評価項目情報」マスター管理DB25、点検箇所別「処置内容情報」マスター管理DB26、納入設備機械/ユニット別「点検記録情報」管理DB27および納入設備機械/ユニット別「点検計画情報」管理DB28を含んでいる。
次に、上述したように構成された保全計画策定支援システム(サーバ1)の動作について説明する。サーバ1は、(1)通常モードおよび(2)点検結果反映モードの2つのモードで動作する。このうち、通常モードでは、データベース2で規定された標準点検周期を補正することなくそのまま用いて、点検すべき点検箇所が特定される。他方、点検結果反映モードでは、過去の点検結果に基づいて標準点検周期が補正された上で、点検すべき点検箇所が特定される。以下、各モードに分けて説明する。
図14は、通常モードにおけるサーバ1の制御部10が実行する処理手順を示すフローチャートである。なお、この処理に先立って、担当者による操作によって端末3がサーバ1にアクセスしているものとする。これにより、サーバ1は、端末3からのリクエストを受付可能な状態にある。
式1;T(l[n,m])=Z(l[n,m])+Y(l[n,m])
式2;T(l[n,m])=X(n)+Y(l[n,m])
ただし、nは、ユニット、mは、ユニットnの主要部位、l[n,m]は、ユニットnの主要部位mの点検箇所を示している。Xは、ステップS102で抽出された稼働開始年月Xであり、Yは、ステップS104で抽出された標準点検周期Yであり、Zは、ステップS105で抽出された工事実施年月Zである。
次に、点検結果反映モードにおけるシステム1の動作について説明する。上述したとおり、点検結果反映モードでは、過去の点検結果に基づいて標準点検周期が補正された上で、点検すべき点検箇所が特定される。
式3;Y'=Y×30
式4;Y''=Y'×(1-α+β)
式5;Y'''=(Y''÷30)の整数値
式6;T’(l[n,m])=Z(l[n,m])+Y'''(l[n,m])
式7;T'(l[n,m])=X(n)+Y(l[n,m])
