25、ation guide Analysis techniques for dependability Guide on methodology FOREWORD 1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of the IEC is to promote in
26、ternational co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, the IEC publishes International Standards. Their preparation is entrusted to technical committees; any IEC National Committee interested in t
27、he subject dealt with may participate in this preparatory work. International, governmental and non-governmental organizations liaising with the IEC also participate in this preparation. The IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with con
28、ditions determined by agreement between the two organizations. 2) The formal decisions or agreements of the IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested Na
29、tional Committees. 3) The documents produced have the form of recommendations for international use and are published in the form of standards, technical specifications, technical reports or guides and they are accepted by the National Committees in that sense. 4) In order to promote international u
30、nification, IEC National Committees undertake to apply IEC International Standards transparently to the maximum extent possible in their national and regional standards. Any divergence between the IEC Standard and the corresponding national or regional standard shall be clearly indicated in the latt
31、er. 5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declared to be in conformity with one of its standards. 6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of p
32、atent rights. The IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 60300-3-1 has been prepared by IEC technical committee 56: Dependability. This second edition cancels and replaces the first edition, published in 1991, and constitutes a ful
33、l technical revision. In particular, the guidance on the selection of analysis techniques and the number of analysis techniques covered has been extended. This bilingual version (2013-03) corresponds to the monolingual English version, published in 2003-01. The text of this standard is based on the
34、following documents: FDIS Report on voting 56/825/FDIS 56/840/RVD Full information on the voting for the approval of this standard can be found in the report on voting indicated in the above table. The French version of this standard has not been voted upon. This publication has been drafted in acco
35、rdance with the ISO/IEC Directives, Part 2. 4 60300-3-1 IEC:2003 The committee has decided that the contents of this publication will remain unchanged until 2007. At this date, the publication will be reconfirmed; withdrawn; replaced by a revised edition, or amended. IMPORTANT The colour inside logo
36、 on the cover page of this publication indicates that it contains colours which are considered to be useful for the correct understanding of its contents. Users should therefore print this document using a colour printer. 60300-3-1 IEC:2003 5 INTRODUCTION The analysis techniques described in this pa
37、rt of IEC 60300 are used for the prediction, review and improvement of reliability, availability and maintainability of an item. These analyses are conducted during the concept and definition phase, the design and development phase and the operation and maintenance phase, at various system levels an
38、d 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. In addition, they are used in logistics and maintenance planning to estimate frequency of maintenance and
39、part replacement. These estimates often determine major life cycle cost elements and should be carefully applied in life cycle cost and comparative studies. In order to deliver meaningful results, the analysis should consider all possible contributions to the dependability of a system: hardware, sof
40、tware, as well as human factors and organizational aspects. 6 60300-3-1 IEC:2003 DEPENDABILITY MANAGEMENT Part 3-1: Application guide Analysis techniques for dependability Guide on methodology 1 Scope This part of IEC 60300 gives a general overview of commonly used dependability analysis techniques.
41、 It describes the usual methodologies, their advantages and disadvantages, data input and other conditions for using various techniques. This standard is an introduction to selected methodologies and is intended to provide the necessary information for choosing the most appropriate analysis methods.
