EN 15341:2007 (E) 4 Introduction This European Standard provid
16、es Maintenance Key Performance Indicators to support management in achieving maintenance excellence and utilize technical assets in a competitive manner. The majority of these indicators apply to all industrial and supporting facilities (buildings, infrastructure, transport, distribution, networks,
17、etc). These indicators should be used to: a) measure the status; b) compare (internal and external benchmarks); c) diagnose (analysis of strengths and weaknesses); d) identify objectives and define targets to be reached; e) plan improvement actions; f) continuously measure changes over time. EN 1534
18、1:2007 (E) 5 1 Scope This European standard describes a system for managing Key Performance Indicators to measure maintenance performance in the framework of the influencing factors such as economical, technical and organisational aspects, to appraise and to improve efficiency and effectiveness to a
19、chieve excellence in maintaining Technical Assets. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including
20、any amendments) applies. EN 13306:2001, Maintenance Terminology IEC 60050-191:1990 International electrotechnical vocabulary; chapter 191: dependability and quality of service 3 Terms and definitions For the purposes of this document the terms and definitions given in EN 13306:2001, IEC 60050-191:19
21、90 and Annex A of this document, together with the following apply. 3.1 indicator measured characteristic (or a set of characteristics) of a phenomenon, according to a given formula, which assess the evolution NOTE Indicators are related to objectives. 3.2 scorecard set of associated, consistent and
22、 complementary indicators providing synthetic and global information NOTE It is a tool for the development and implementation of a strategy and for monitoring progress towards the goals outlined in the strategy. 4 Maintenance Performance Maintenance Performance is the result of actively using resour
23、ces to retain an item, or restore it to a state in which it can perform its required function. It can be expressed as an achieved or expected result. Maintenance Performance depends on both external and internal factors such as: location, culture, transformation and service processes, size, utilizat
24、ion rate and age and is achieved by implementing corrective, preventive and improvement maintenance, using labour, information, materials, organisational methodologies, tools and operating techniques. Maintenance Performance is an outcome of complex activities which can be evaluated by appropriate i
25、ndicators to measure both the actual and expected results. EN 15341:2007 (E) 6 5 System of indicators 5.1 General To cover this aspect of maintenance, this system of key performance indicators is structured into three groups: economic, technical and organisational. These proposed indicators can be e
26、valuated as a ratio between factors (numerator and denominator) measuring activities, resources or events, according to a given formula. These indicators are used to measure any quantitative aspect or characteristic of an indenture level and homogeneous comparison. Whenever a factor is defined using
27、 the words “internal” or “external”, the derived indicator, should also be used only for “internal” or “external” influences. 5.2 Objectives When the actual or expected performance is not satisfactory, it encourages management to define objectives and strategies to improve from an economic, technica
28、l or organisational point of view using the following system of indicators, allowing the organisation to: a) measure the status; b) evaluate the performance; c) compare performance; d) identify strengths and weaknesses; e) control progress and changes over time. Measurement and analysis of these ind
29、icators can help management to: f) set objectives; g) plan strategies and actions; h) share the results in order to inform and motivate people. These indicators can be used: i) on a periodic basis, for instance by preparing and following-up a budget, and during performance assessment; j) on a spot b
30、asis, for instance within the framework of specific audits, studies and/or benchmarking. The period of time to be considered for measurement depends on the company policy and management approach. 5.3 Architecture of key indicators Figure 1 illustrates the external and internal factors that influence
31、 maintenance performance and consequently the three groups of key indicators. External factors are variable conditions outside company management control. Internal factors are referred to the group, company, factory, plant outside of the maintenance management control, but inside of the company mana
32、gement control. EN 15341:2007 (E) 7 When using the key maintenance performance indicators, it is important to consider these influencing factors as prerequisites to avoid misleading evaluations and comparisons due to not having homogeneous conditions.

35、Internal influencing factorsFigure 1 Maintenance influencing factors and Maintenance Key Performance Indicators 6 Indicators 6.1 General When calculating the indicators, denominator and numerator, factors shall be referred to the same activity/item and to the same period of time (year, quarter, mont
36、h, etc.). These factors are defined and explained in Annex A of this document. Most indicators can be used at different levels depending on whether they are used to measure the performance of plant production, one production line, or a given equipment or item, etc. The indicators in this standard ar
37、e structured in levels that represent their breakdown structure. Indicators below level one are a detailed description of indicators at a higher level. The magnitude and number of levels may be established by each company. The indicators in this standard are numbered by level as a means of identific
38、ation, not to indicate importance. These indicators refer to internal maintenance, external maintenance or both. The term “Time” is generally used to describe time units related to equipment and its performance. The terms “Hours” or “Man-hours” describes the hours delivered to maintenance activities
