Purpose – The purpose of this paper is to describe how a risk‐based dependability approach can be used to link maintenance performance measurement and management to overall objectives within an organization. Design/methodology/approach – The applied study approach is a case study at Trafikverket (the Swedish Transport Administration). Qualitative data were collected through interviews, workshops and document studies, while quantitative data was collected through data bases. As a framework for analysis, international standards within the risk and dependability areas were applied. Finally, the conclusions of the study were verified by key informants. Findings – Through the proposed risk‐based dependability approach, critical availability goals are communicated with and involve top management. The approach also contributes to enhanced data and information quality by pinpointing critical data and information for dependability management activities. The proposed availability indicator can be used to monitor the effect of dependability management activities aimed at different indenture levels of the infrastructure and related to the responsibility of different hierarchical levels of the organization, e.g. different maintenance echelons. Practical implications – The proposed approach strengthens the internal control of an organization by supporting the achievement of: objectives that are aligned with and support the mission; operations with an effective and efficient use of resources; reliable operational and financial reporting; compliance with applicable laws and regulations. Originality/value – By integrating risk management in the work with availability goals included in the balanced scorecard, a more holistic and risk‐based dependability management practice is achieved.

Risk‐based dependability approach to maintenance performance measurement

“…Hence, risk management includes a process, as well as information security. However, maintenance may also be viewed as a process as described in IEC 60300-3-14, which is used by Karim et al (2008aKarim et al ( ), 2008bKarim et al ( , 2009 within the context of eMaintenance to emphasize information logistic aspects instead of technology. From an information security perspective, one aspect of the process approach is that the users are encouraged to emphasize the importance of the following (adapted from ISO/IEC 27000):…”

“…Furthermore, the PDCA model can also be seen in the maintenance process described in IEC 60300-14 (maintenance and maintenance support), which has been used in the context of eMaintenance (see e.g. Karim et al 2008aKarim et al , 2008bKarim et al , 2009. Even though the model is used in slightly different ways, its role is to highlight the importance of continuous improvement.…”

“…These challenges can to some extent be met by eMaintenance, which aims at the provision of information logistic solutions to all stakeholders of the maintenance process through utilization of new and innovative information and communication technology (ICT) (see, e.g. Lee 2003;Levrat et al 2008;Karim et al 2008aKarim et al , 2008bKarim et al , 2009). However, in order to achieve a true risk-based maintenance approach that considers the overarching strategic goals of an organization, it is also necessary to apply principles, frameworks, processes, methodologies and tools from the risk management area.…”

Maintenance is one approach to managing risk by a reduction of the probability of failure of technical systems and/or the consequences of their failure. However, history has shown that erroneous maintenance also can lead to reduced quality, incidents and accidents with extensive losses. Today, eMaintenance promises great opportunities for a paradigm shift from a rather narrow, condition-based maintenance approach with focus on a technical system's health to a true risk-based maintenance approach that also considers organizational excellence. This is achieved by proper information logistic solutions that address the needs of all stakeholders of the maintenance process, which are possible due to new and innovative information and communication technology (ICT). However, all opportunities are also linked with some threats, which are seldom highlighted in the case of eMaintenance. In this article, a risk management framework for evaluation of eMaintenance solutions is proposed. The framework is based on a combination of international standards (e.g. ISO 31000, ISO/IEC 27000, and IEC (2004) 60300-3-14) to achieve integrated Enterprise Risk Management (ERM) and enable a linkage of eMaintenance to the strategic goals of an organization. The framework is illustrated in the railway context of Trafikverket (2010b) (the Swedish Transport Administration).

“…Innovative use of Information & Communication Technology is important for such improvements. [1][2][3][4][5] However, the nature of collected condition data usually violates common statistical assumptions, such as samples being taken from an independently, identically distributed normal distribution. Naturally, the violations of these assumptions differ from being of no practical consequence to invoking serious errors.…”

Data Analysis for Condition‐Based Railway Infrastructure Maintenance

Condition assessment is crucial to optimize condition-based maintenance actions of assets such as railway infrastructure, where a faulty state might have severe consequences. Hence, railways are regularly inspected to detect failure events and prevent the inspected item (e.g. rail) to reach a faulty state with potentially safety critical consequences (e.g. derailment). However, the preventive measures (e.g. condition-based maintenance) initiated by the inspection results may cause traffic disturbances, especially if the expected time to a faulty state is short. The alarm limits are traditionally safety related and often based on geometrical properties of the inspected item. Maintenance limits would reduce the level of emergency, producing earlier alarms and increasing possibilities of planned preventive rather than acute maintenance. However, selecting these earlier maintenance limits in a systematic way while balancing the risk of undetected safety-critical faults and false alarms is challenging.Here, we propose a statistically based approach using condition data of linear railway infrastructure assets. The data were obtained from regular inspections done by a railway track measurement wagon. The condition data were analysed by a control chart approach to evaluate the possibility for earlier detection of derailment hazardous faults using both temporal and spatial information.The study indicates that that the proposed approach could be used for condition assessment of tracks. Control charts led to earlier fault warnings compared to the traditional approach, facilitating planned condition-based maintenance actions and thereby a reduction of track downtime.
