機械的製品の信頼度モデル―現場データによる直接的誘導―

概要

論文の詳細を見る
A new approach is outlined for analysing the field reliability of the mechanical items which are under preventive maintenance.<BR>A failure-mechanism model is obtained directly from the field data, by a strict interpretation discriminating the informations concerned about the failures and prefailure defects or abnormalities, recorded in the conventional reports. It can be approximated by a known distribution and conveniently used for data analysis. The validity of this macroscopic model is shown in the applications to several cases of actual data of the marine products.<BR>The approach does not require any prior knowledge of the distribution, and Pandit called it “Data Dependent Systems Approach” in his Tool-life investigations.
