PurposeThe findings of this study have lightened the focal research areas in maintenance planning and scheduling. These also served as effective guidelines for future studies in this area. This research, therefore, contributes in fulfilling the gap by carrying out an SLR of contemporary research studies in the area of models for maintenance planning and scheduling. At present, SLR rooted in BA has not been carried focusing on a survey over models for maintenance planning and scheduling. SLR uses advanced scientific methodologies from BA tools to unveil thematic structures.Design/methodology/approachWe have systematically reviewed over 1,021 peer-reviewed journal articles. Advanced contemporary tools from Bibliometric Analysis (BA) are used to perform a Systematic Literature Review (SLR). First, exploratory analysis is presented, highlighting the influential authors, sources and region amongst other key indices. Second, the large bibliographical data is visualized using co-citation network analyses, and research clusters (themes) are identified. The co-citation network is extended into a dynamic co-citation network and unveils the evolution of the research clusters. Last, cluster-based content analysis and historiographical analysis is carried out to predict the prospect of future research studies.FindingsBA tools first outlined an exploratory analysis that noted influential authors, production countries, top-cited papers and frequent keywords. Later, the bibliometric data of over 1,021 documents is visualized using co-citation network analyses. Later, a dynamic co-citation analysis identified the evolution of research clusters over time. A historiographical direct citation analysis also unveils potential research directions. We have clearly observed that there are two main streams of maintenance planning and scheduling applications. The first has focused on joint maintenance and operations on machines. The second focused on integrated production and maintenance models in an echelon setting for unrealizable production facilities.Originality/valueThere are many literature review-based research studies that have contributed to maintenance scheduling research surveys. However, most studies have adopted traditional approaches, which often fall short in handling large bibliometric data and therefore suffer from selection biases from the authors. As a result, in this area, the existing reviews could be non-comprehensive. This study bridges the research gap by conducting an SLR of maintenance models, which to the best of our knowledge, has not been carried out before this study.

PurposeMaintenance management is perceived as fundamental for ensuring that physical assets contribute to business outcomes. In this context, the purpose of this paper is to elaborate a novel maintenance management framework for asset management (MMFAM) based on ISO 55000 series guidelines.Design/methodology/approachThe paper proposes an MMFAM that intends to translate the technical requirements set out in the ISO 550001 standard to the maintenance stage of asset management. First, the framework is modeled using consideration based on the analysis of the ISO 55000 series and the review of previous maintenance management frameworks. Then, support tools are presented that collaborate for the implementation of the processes and activities provided for in the MMFAM.FindingsThe proposed MMFAM was modeled using a Business Process Model and Notation since it is a standardized graphical notation for process modeling and contributes to the understanding of the framework. In addition, the applicable tools were presented for the practical implementation of MMFAM processes and activities.Practical implicationsThe paper is expected to contribute to maintenance practitioners and researchers in understanding and disseminating a novel maintenance management framework that is in line with asset management through the international ISO 55000 series.Originality/valueAs it is essentially multidisciplinary and complex, asset management has still been little explored. Moreover, the requirements for implementing an asset management system, as explained in the ISO 55001 standard, only provide what needs to be done, but not how to do it. Accordingly, the paper fills a gap in maintenance management literature, as it addresses the ISO 55000 series for asset management in depth.

PurposeThe purpose of this paper is to investigate the performance of a turbine structure of the oil and gas Egyptian company in terms of reliability, mean time to failure (MTTF), mean time to repair (MTTR) and mean time between failures (MTBF) under fuzzy environment and working criteria. This paper examines the impact of the failure of various components on the complete turbine structure of the oil and gas system.Design/methodology/approachTo overcome the problem of uncertain behavior of available data for various components, the right triangular generalized fuzzy number (RTrGFN) is proposed to be taken into the account to express the uncertainty which attains some tolerance in data. Furthermore, reliability indices are calculated with the help of the Lambda Tau method and the arithmetic operations on right generalized triangular fuzzy numbers (RTrGFN).FindingsThis paper explores the reliability of a repairable 3 out of 4 structure of turbines and along with the other parameters namely MTTF, MTTR and MTBF; under a fuzzy environment. Failure rates and repair times are expected to be exponential. The ranking of components of the structure is being found to decide the priority for maintenance.Originality/valueThis paper investigates the performance of the system with different spread/tolerance like 15%, 25% and 50% of crisp data. It helps to predict realistic results in the range value. To enhance the system's performance, the most important item of the system requires greater attention. For this, the authors find the sensitive part by ranking. For ranking, an extended approach has been developed to find the sensitive unit of the system by using the right triangular generalized fuzzy number. This paper explores the most and least sensitive component of the system, which helps the maintenance department to plan the maintenance action.

PurposeThe purpose of the research was to verify if there was an alignment between the risk assessed and the risk perceived or if some inconsistencies arise that could affect the safety of the operators. In fact, eventual inconsistencies should be analysed, interpreted and managed to maximise the information and training process, if needed.Design/methodology/approachThe adopted approach in this work relies on the collection of the perception of the operators about the level of risk in a work environment and its comparison with the level of risk assessed by the company. The collection of data was performed through a survey designed ad hoc, subministrated to all the workers in the area under study, being them involved in the production and in the maintenance. The survey’s structure and aim were described to the operator by the researchers and returned by the operators in a voluntary and anonymous way.FindingsThe information collected allowed identifying a gap between the risk assessed and the risk perceived by the plant operators. For example, for the use of personal protective equipments, the data highlighted a discrepancy between the knowledge about their need and the behaviour in using them, which resulted in the revision of both communication and training processes, with the adoption of a more participatory approach.Originality/valueThe originality of the work is in the data set, originally collected for this study, in the data collection form, also devised specifically for the case under study, despite it can be easily adapted for other work environment, and in the purpose itself, aimed at pushing risk assessment towards a personalised and adaptive approach.

PurposeThe conventional methods practiced by Development and Facilities Management Unit (UPPF) faced issues due to management deficiencies and negligent staffs to handle operation and maintenance processes of Chemical Facility (CFs) management at Malaysian Polytechnic. The prime objective of this paper is to improve the conventional methods which tend to be both cumbersome and ineffective in the Maintenance Management Systems (MMS) for UPPF at Malaysian Polytechnic.Design/methodology/approachPrimary data was gathered through the interview to develop the proposed system. The major conclusion drawn from the interview results was that there is a lack of comprehensive MMS that integrate operation and maintenance processes of CF management and software programming that provide the guides for decision-making processes. The interview results also revealed irregularities within the Malaysian Polytechnic's maintenance management database.FindingsThe conventional methods had significantly little emphasis on defect diagnosis tools. It had also increased the inadequate strategic decision making to analyse information in improving the maintenance project outcomes for Malaysian Polytechnic's building. New MMS tools is suggested from findings and lessons learned as a good practice to reduce the frequent overhauling and repairs on the durability's performance and design of building control instrument.Originality/valueThe new MMS potentially transform operation and maintenance processes of CF management into one of the most sophisticated technologies by providing access to all information published by all Malaysian Polytechnics institutions. This is in order to foster financial cooperation, the idea that being that Polytechnics who compete with one another become financially independent towards successful achievements of CF management for laboratory building and equipment.

PurposeMaintenance organizations continue to be under pressure to systematically eliminate maintenance wastes and deliver services that their customers value. To this end, maintenance managers are implementing lean maintenance practices. But how does one consistently estimate the leanness of these practices in their organization? The purpose of this paper is to develop a framework for a metrics – referred to as the lean maintenance index (LMI) that can help managers estimate the leanness of maintenance practices.Design/methodology/approachBased on a comprehensive review of literature in the domain, this study identifies four factors and nineteen subfactors that are essential for the success of a lean maintenance program. A fuzzy-set-theory-based assessment framework is developed that can be used by an in-house team to measure the degree of implementation of lean maintenance practices in their organization. The authors applied the framework to a maintenance workshop that services diesel engines and other prime movers.FindingsThe framework provides maintenance managers valuable insights to help identify the strengths and weaknesses of their organization vis-à-vis their maintenance practices, thus enabling them come up with a firm action plan for future process improvements.Originality/valueThis paper adapts the concept of agility and readiness to maintenance work. A key contribution of this study is the identification of factors and subfactors that forms the basis to estimate the leanness of maintenance practices in an organization. Another contribution is its application to a large maintenance workshop that demonstrates the ease of its implementation. Future research in this area can help identify more factors and subfactors and thus improve the estimation of leanness.

PurposeThis paper aims to prioritize the factors for the successful implementation of total productive maintenance (TPM).Design/methodology/approachThe technique used for prioritization is the analytical hierarchy process (AHP).FindingsThe commitment and involvement of the top management, i.e. the leadership team, is the most critical success factor in the successful implementation of TPM. Employee training is another vital factor. Top management should also encourage a culture favorable for information flow, equipment ownership, the involvement of people and quality management throughout the organization.Research limitations/implicationsManufacturing organizations interested in improving productivity through the implementation of TPM should first involve the leadership team and seek their full support and train all the employees in this philosophy. However, the findings cannot be generalized for global application due to the inputs taken from experts in AHP from limited geography.Practical implicationsReducing production costs is a universal expectation of business leaders. TPM can be used as a long-term strategy to improve productivity by the organization.Social implicationsAll employees have to be trained in this philosophy, and as part of the training and the implementation of TPM, they feel empowered and committed to the organization.Originality/valueThis study has illustrated the use of AHP for the prioritization of success factors. Prioritization of success factors will help in strategy formulation by management for effective maintenance. It will help in improving the productivity and performance of the organization.

PurposeThe purpose of this paper is to present an integrated strategy for inventory control and preventive maintenance planning for a single-machine production system with increasing failure rates.Design/methodology/approachThere are three scenarios for solving presented model. The strategy is such that the production component is placed under maintenance as soon as it reaches the m level or in the event of a malfunction earlier than m. Maintenance completion time is not predictable.

PurposeThe purpose of this paper is to demonstrate industrial Internet of Things (IIoT) solution to improve the equipment condition monitoring with equipment status data and process condition monitoring with plasma optical emission spectroscopy data, simultaneously. The suggested research contributes e-maintenance capability by remote monitoring in real time.Design/methodology/approachSemiconductor processing equipment consists of more than a thousand of components, and unreliable condition of equipment parts leads to the failure of wafer production. This study presents a web-based remote monitoring system for physical vapor deposition (PVD) systems using programmable logic controller (PLC) and Modbus protocol. A method of obtaining electron temperature and electron density in plasma through optical emission spectroscopy (OES) is proposed to monitor the plasma process. Through this system, parts that affect equipment and processes can be controlled and properly managed. It is certainly beneficial to improve the manufacturing yield by reducing errors from equipment parts.FindingsA web-based remote monitoring system provides much of benefits to equipment engineers to provide equipment data for the equipment maintenance even though they are physically away from the equipment side. The usefulness of IIoT for the e-maintenance in semiconductor manufacturing domain with the in situ monitoring of plasma parameters is convinced. The authors found the average electron temperature gradually with the increase of Ar carrier gas flow due to the increased atomic collisions in PVD process. The large amount of carrier gas flow, in this experimental case, was 90 sccm, dramatically decreasing the electron temperature, which represents kinetic energy of electrons.Research limitations/implicationsSemiconductor industries require high level of data security for the protection of their intellectual properties, and it also falls into equipment operational condition; however, data security through the Internet communication is not considered in this research, but it is already existing technology to be easily adopted by add-on feature.Practical implicationsThe findings indicate that crucial equipment parameters are the amount of carrier gas flow rate and chamber pressure among the many equipment parameters, and they also affect plasma parameters of electron temperature and electron density, which directly affect the quality of metal deposition process result on wafer. Increasing the gas flow rate beyond a certain limit can yield the electron temperature loss to have undesired process result.Originality/valueSeveral research studies on data mining with semiconductor equipment data have been suggested in semiconductor data mining domain, but the actual demonstration of the data acquisition system with real-time plasma monitoring data has not been reported. The suggested research is also valuable in terms of high cost and complicated equipment manufacturing.
