簡介(introduction)

The analysis techniques described in this part of IEC 60300 are used for the prediction, review and improvement of reliability, availability and maintainability of an item.  
國際可恃性標準 IEC 60300 系列中的 IEC 60300-3-1 詳述可恃性分析技術。

These analyses are conducted during the concept and definition phase, the design and development phase and the oparation and maintenance phase, at various system levels and degrees of detail, in order to evaluate, determine and improve the dependability measures of an item.  They can also be used to compare the results of the analysis with specified requirements.  
這些分析技法主要作為預估、審查與改善物品的可靠度、可用度與維護度之用。這些分析方法可在概念與定義階段、設計與發展階段、及營運與維護階段，就各種系統層級及細節程度，進行分析，以便評估、決定及改善物品的可恃性度量。這些分析方法同時可應用在與特定要求的分析結果作比較。

In addition, they are also used in logistics and maintenance planning to estimate frequency of maintenance and part replacement.  These estimates often determine major life cycle cost elements and should be carefully applied in life cycle cost and comparative studies.  
除此之外，這些分析技法同時也使用在後勤與維護規劃，以便推定維護與零件更換頻度，這些推定值通常決定大部分的生命週期成本要項，因此在進行生命週期成本與比較研究時，應該小心應用。

In order to deliver meaningful results, the analysis should consider all possible contributions to the dependability of a system: hardware, software, as well as human factors and organizational aspects.  
為提出有意義的結果，分析工作應該考量所有可能影響系統可恃性的項目，包括：硬體、軟體、以及人員因子與組織方面。
