EN 15341:2007 (E) 4 Introduction This European Standard provides Maintenance Key Performance Indicators to support managemen
17、t 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, etc). These indicators should be used to: a) measure the statu
18、s; 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 15341:2007 (E) 5 1 Scope This European standard describes a system
19、 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 achieve excellence in maintaining Technical Assets. 2 Normative

23、mation 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 resources to retain an item, or restore it to a state in which it ca
24、n 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, utilization rate and age and is achieved by implementing corrective, p
25、reventive 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 indicators to measure both the actual and expected results. EN
26、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 evaluated as a ratio between factors (numerator and denominator
27、) 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 the words “internal” or “external”, the derived indicator, sh
28、ould 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, technical or organisational point of view using the following system o
29、f 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 indicators can help management to: f) set objectives; g) plan str
30、ategies 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 basis, for instance within the framework of specific audits, st
31、udies 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 maintenance performance and consequently the three groups of
32、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 management control. EN 15341:2007 (E) 7 When using the key mainten
33、ance performance indicators, it is important to consider these influencing factors as prerequisites to avoid misleading evaluations and comparisons due to not having homogeneous conditions.

36、actors 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, month, etc.). These factors are defined and explained in Annex A o
37、f 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 are structured in levels that represent their breakdown structur
38、e. 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 identification, not to indicate importance. These indicators refer to i
39、nternal 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. EN 15341:2007 (E) 8 6.2 Economical Key Indicators 6.2.1 LEVE
