Socio-technical Integrity in Maintenance Activities
Published in Peter Vink, Advances in Social and Organizational Factors, 2012
Malgorzata Jasiulewicz-Kaczmarek
The main purpose of maintenance engineering is to reduce the adverse effects of breakdown and to maximize the availability at minimum cost, in order to increase the performance and improve the dependability level. Thus, to maintain a manufacturing system means to implement objectives (cost, delay, quality, etc.) fixed by the direction of the production, taking surrounding events (risks, perturbation, etc.) into account. In every case the maintenance system must: ensure smooth and reliable operation of the production line,integrate the human and technical resources, technical knowledge management and capitalization,be able to reconfigure manufacturing systems for the production of innovative products.
Methodology and Application of RAM Management along the Railway Rolling Stock Life Cycle
Published in Qamar Mahboob, Enrico Zio, Handbook of RAMS in Railway Systems, 2018
Maintenance engineering is the discipline of applying engineering concepts to ensure the availability, reliability, safety, and cost effectiveness of technical systems. Maintenance engineering is closely related to reliability engineering. Particularly, the systematic analysis of failure behavior enables knowledge transfer and optimization of maintenance strategies and concepts (Figure 21.8).

In technical fields, the most prominent changes were: - Standardize and optimize resources; systematic utilization of statistical tools.- The fixed scale assures that all equipment has its own operating team, which is committed to the operational performance of its respective equipment.- Work teams know exactly what is happening with their equipment and they are constantly discussing and treating the problems.- Housekeeping activities are focused. Check lists are used to evaluate the general condition of equipment cleanliness and safety.- Observation to the Operational Procedures seeking minimum errors.- Operators are trained in how to recognize vital equipment’s indications, basic working principles and simple maintenance activities. This training was administered by experienced mechanics and technicians. All mechanics were trained, also, in subjects concerning operation of the equipment.- Emphasis on maintenance engineering function aiming at better reliability and availability of equipment.- Improve workers productivity by better organization and planning.- Ensure effective preventive maintenance and reduce to a minimum the unscheduled repairs. More planned and scheduled work.
Integrated scheduling of distributed service resources for complex equipment considering multiple on-site MRO tasks

In the past decades, researchers have contributed a wealth of results in multitudes of fields related to MRO. Many scholars have explored the conceptual framework and supportive technology to improve MRO services. Crespo Marquez and Gupta (2006) proposed a maintenance framework from the perspectives of information technology, maintenance engineering and relationship management. Meanwhile, they constructed a management system consisting of e-maintenance, on-line failure prediction and customised maintenance. Li et al. (2010) put forward the integrated modules, critical methods and technologies to support the MRO service system which is oriented to product lifecycle. Zhang et al. (2015b) pondered over the advantages of cloud manufacturing and then provided a cloud-based MRO framework, namely lean MRO, to enhance productivity and reduce costs. Yang and Hu (2019) analysed the collaborative MRO service chain of complex products, and then proposed uncertainty analysis methods to build the uncertainty transmission relationship model.
Value creation in the engineering enterprise: an educational perspective
Published in European Journal of Engineering Education, 2019
James Trevelyan, Bill Williams
Engineering operations, engineering asset management and maintenance engineering (collectively known as sustainment) are critical for protecting value embodied in engineered products, systems and business processes. These require elaborate technical coordination and other collaboration performances by engineers. For example, a gas pipeline needs carefully planned and implemented inspections and maintenance. Without these measures, the condition of the pipeline can deteriorate, resulting in considerable value destruction. Energy, water, transport, communication and sanitation services are critical for the functioning of all human societies: inadvertent failure can lead to enormous value destruction, disease and deaths, far beyond the replacement value of the engineered systems themselves. Accountants use a fixed rate of depreciation as a crude measure of value loss but the rate of depreciation used for accounting purposes is often unrelated to the actual loss of value that depends on how maintenance is actually performed. This is seldom represented adequately by recorded data (Nair and Trevelyan 2008; Gouws 2014). For example, an accountant may wish to maximise losses early in the life of a productive asset in order to take advantage of certain taxation rules. A very different strategy is needed to maximise value protection for the physical asset.
Integrated production quality and condition-based maintenance optimisation for a stochastically deteriorating manufacturing system

Thanks to the development of sensor and information technologies, we can monitor the deterioration level of systems to facilitate the prediction of failures. Therefore, the condition-based maintenance (CBM) has been widely used in maintenance engineering due to its effectiveness and efficiency. To help the manufacturer coordinate and balance production quality and CBM decisions, there is a substantial need to develop new integrated models where maintenance programs are developed and optimised on the basis of information collected through condition monitoring and product quality requirements. In the last decade, increasing research efforts have been made on CBM modelling and optimisation. CBM isrecognised to be more effective because it takes into account the real-time condition of the system (e.g. degradation level). In the existing literature, a large variety of mathematical models, methods as well as techniques have been developed for CBM (Pandey, Cheng, and van der Weide 2011; Liu et al. 2013; Mercier and Castro 2013; Rafiee, Feng, and Coit 2015). For a comprehensive literature review in CBM, one may refer to Jardine, Banjevic, and Lin (2006), Scarf (2007) and van Noortwijk (2009), and to the recent review by Alaswad and Xiang (2017).
