Description
複数の前記回線で試験を実行し、回線毎の試験データの1つまたは複数の要素を得る工程と、
共通故障特性で回線を識別するために試験データを分析する工程と、
ノードから故障特性を取り除くために必要とされる保守タスクの緊急性の相対的な基準を提供する共通故障特性で、回線数に基づいてノード毎にスコアを確立する工程と、
を備える。
(この場合「p」は、本実施形態の中では0.5に設定されるレンジパラメータである。)
この式は、AHFを示す第1の回線からそうするための最後の回線までから選択された表1からのデータのサブセットであるグループを参照する。前記の表1ではグループは位置4から位置24まで通る。該式は分析されているグループ中の疑わしいものの総数を取り、それをグループ内の疑わしいものの総数で除算し、これをレンジパラメータpの累乗に乗算する。したがって本例では、クラスタ範囲は(24/13)0.5=1.84として計算される。次にクラスタ範囲は、AHFを示す回線の間に物理的に位置している明らかに障害のない回線(前記表1中の「a」)のどれがAHFを示すとして処理されるべきかを判断するために使用される。言い換えると、2(またはそれ以上)の「b」の間に1のみの「a」がある場合には、該「a」は「b」、及びその隣接する「b」、つまり1<クラスタ範囲=1.84であるクラスタの一部として処理される。2の「a」がある場合には、これらは隣接する「b」、つまり2>クラスタ範囲=1.84であり、クラスタを形成するとして処理されないだろう。クラスタ範囲を表1に示される結果に適用すると、以下の表2に描かれる次の結果が生じる。
Claims (5)
- 複数のノードを通過する複数の回線を備える通信網のためのフォルトマネジメントシステムを動作する方法であって、
a)回線毎にテストデータの1つまたはそれ以上の要素を得るために複数の前記回線上でテストを実行する段階と、
b)故障が所定の期間内に発生する可能性があることを示す共通の特性を有する回線を識別するためにテストデータを分析する段階と、
c)該共通の特性の原因が位置する可能性が最も高いノードを指摘するためにノード毎に共通の特性を有する回線の物理的なクラスタ化の相対的な基準に基づきノード毎にクラスタ化スコアを計算する段階と、
d)共通の特性を有する回線数に基づきノード毎に優先順位スコアを計算する段階であって、該スコアはノードから該特性を取り除くために必要とされる保守タスクの緊急性の相対的な基準を提供するものと、を備える方法。 - ワイヤAとバッテリー、又はワイヤBとバッテリーのいずれかの間の抵抗が400キロオーム未満の値を有するならば、故障が1年の期間内に発生する可能性があることを示す請求項1記載の方法。
- ノード毎のスコアの計算において、使用されていない回線と、動作中の回線と、故障が疑われる回線と、実際に故障の回線の数が、ノードの優先順位スコアを計算するのに使用される請求項1に記載の方法。
- 複数のノードを通過する複数の回線を備える通信網のためのフォルトマネジメントシステムであって、
回線毎にテストデータの1つまたはそれ以上の要素を得るために複数の前記回線上でテストを実行するように動作可能な手段と、
故障が所定の期間内に発生する可能性があることを示す共通の特性を有する回線を識別するためにテストデータを分析するように動作可能な手段と、
共通の特性の原因が位置する可能性が最も高いノードを指摘するためにノード毎に共通の特性を有する回線の物理的なクラスタ化の相対的な基準に基づきノード毎にクラスタ化スコアを計算するように動作可能な手段と、
共通の特性を有する回線数に基づきノード毎に優先順位スコアを計算するように動作可能な手段であって、該スコアはノードから該特性を取り除くために必要とされる保守タスクの緊急性の相対的な基準を提供するものと、を備えるシステム。 - 請求項1乃至請求項3のいずれか1項に記載の方法を実行するためのコンピュータ実行可能コードを備えるコンピュータプログラム。
