Abstract
Purpose
The purpose of this paper is to describe an application of an effective risk-based methodology to support a living maintenance programme for railway infrastructure.
Design/methodology/approach
The overall research strategy is a single case study of switches and crossings at the Iron Ore Line in northern Sweden. The analysis was performed as a risk workshop guided by a methodology that integrates reliability-centred maintenance and barrier analysis.
Findings
The applied methodology is valuable to systematise and improve the existing maintenance programme, as well as supporting a continued living maintenance programme.
Research limitations/implications
The single case study approach may decrease the validity of the achieved results. However, similar case studies corroborate the results, which affect the validity in a positive way.
Practical implications
The resulting maintenance programme is effective, through compliance with external requirements, and more efficient, through improvements of tasks and intervals.
Social implications
An enhanced railway infrastructure maintenance programme contributes to improved safety, punctuality, and costs. Hence, railway becomes a more attractive mode of transport. Thereby, it also supports a safety performance of the railway that society is willing to pay for.
Originality/value
Significant improvements of the maintenance programme are achieved through adjustment of inspection intervals and tasks. The results also support the development of indicators, monitoring, and continuous improvement.

Abstract
Economic and market conditions have resulted in the use of commercial jet transport airplanes well beyond their design service objective (DSO). Air transport industry consensus is that older jet transport airplanes will continue to be in service despite an anticipated substantial increase in the required maintenance. Based on economical considerations, established operators may replace their airplanes beyond DSO with new ones. At the same time these older airplanes are sold to operators with little or no knowledge and experience of the aging airplane maintenance programs. Discusses the damage tolerance concept, its relation to airplane age and its evolution that is fail‐safe to damage tolerance based maintenance certification for jet transport airplanes. Also, this paper will discuss a process for upgrading structural inspection programs for older airplanes to damage tolerance standard per MSG‐3 Rev. 2 analysis. Finally, sub‐surface corrosion on principal airplane structures and its effect on airplane safety will be discussed.

Abstract
Purpose
Medical technologies and assets are one of the main drivers of increasing healthcare cost. The rising number and complexity of medical equipment have forced hospitals to set up and regulate medical equipment management programs to ensure critical devices are safe and reliable. The purpose of this paper is to gain insights into maintenance management-related activities for medical equipment. The paper proposes applying a tailored reliability-centered maintenance (RCM) approach for maintenance activities selection for medical equipment. Such approach will support assets management teams in enhancing operation, decrease risk and cost, and ultimately improve health of patients served by these equipment.
Design/methodology/approach
The traditional RCM approach will be used with a focus on criticality reduction. By criticality, the authors refer to the severity of failures and occurrence. The proposed method relies on the use of reliability growth analysis for opportunity identification followed by a thorough failure mode and effect analysis to investigate major failure modes and propose ways to reduce criticality. The effectiveness of the proposed method will be demonstrated using a case of one of the leading obstetric and gynecological hospitals in United Arab Emirates and in the Gulf Cooperation Council region.
Findings
The case examines the relationship between the current practice of planned preventive maintenance and the failure rates of the equipment during its life span. Although a rigorous preventive maintenance program is implemented in the hospital under study, some critical equipment show an increasing failure rates. The analysis highlights the inability of traditional time-driven preventive maintenance alone in preventing failures. Thus, a systematic RCM approach focused on criticality is more beneficial and more time and cost effective than traditional time-driven preventive maintenance practices.
Practical implications
The study highlights the need for utilizing RCM approach with criticality as the most important prioritization criterion in healthcare. A proper RCM implementation will decrease criticality and minimize the risk of failure, accidents and possible loss of life. In addition to that, it will increase the availability of equipment, and reduce cost and time.
Originality/value
This paper proposes a maintenance methodology that can help healthcare management to improve availability and decrease the risk of critical medical equipment failures. Current practices in healthcare facilities have difficulty identifying the optimal maintenance strategy. Literature focused on medical maintenance approach selection is rather limited, and this paper will help in this discussion. In addition to that, the Association for the Advancement of Medical Instrumentation supports the initiative of adopting RCM on a large scale in healthcare. Therefore, this paper address the gap in the literature for medical equipment maintenance and the work is in line with the recommendation of leading healthcare association. The paper also presents statistical review of the total number of received maintenance work orders during one full year in the hospital under study. The analysis supports the need for more research to examine current practice and propose more effective maintenance approaches.

Abstract
Purpose
The purpose of this paper is to discuss the concept of strategy in the field of heritage conservation, with a focus on a new conservation approach that promotes the empowerment of local communities and sustainable development: a living heritage approach.
Design/methodology/approach
The approaches to heritage conservation are outlined: a material-based approach defines the principles of western-based conservation, a values-based approach expands these principles, while a living heritage approach clearly challenges the established principles. These approaches are, then, analysed from the perspective of strategy, and a living heritage approach is seen as an example of strategic innovation. The process by which ICCROM develops a living heritage approach at an international level is also examined.
Findings
Choosing the “appropriate” conservation approach depends on the specific conditions of each heritage place. Yet, for the cases of living heritage in particular (with communities with an original connection with heritage) a living heritage approach would be more preferable. Living heritage approach can be seen as an example of a strategic innovation in the field of heritage conservation: it proposes a different concept of heritage and conservation (a new WHAT), points at a different community group as responsible for the definition and protection of heritage (a new WHO), and proposes a different way of heritage protection (a new HOW).
Practical implications
A living heritage approach (presented in the paper) may potentially influence the theory as well as the practice of heritage conservation in a variety of parts and heritage places in the world, especially in terms of the attitude towards local and indigenous communities.
Originality/value
Developing a new approach is, in a sense, developing a new strategy. In this context, the paper aims at bringing the insight of business strategy into the field of heritage conservation.
