PurposeNew maintenance hypotheses such as lean smart maintenance emphasized internal integration. Since the maintenance process is not fully integrated with other business processes, it indicates that some of the problems in the maintenance process are caused by other departments. Additionally, nothing can be managed or improved without first measuring it. In order to enhance internal integration, this study developed a model that makes use of information systems data to examine synchronization and collaboration across departments engaged in maintenance operations.Design/methodology/approachThis research connects maintenance management and business process management through information systems. A conceptual module model based on CMMS is proposed that will use data which are already available in CMMS and, using process mining, will assess the level of synchronization between departments within an organization.FindingsThis conceptual model will serve as a roadmap for creating better value-added CMMS software. This system operates as a performance measurement tool in three majors, including organizational analysis, workflow analysis and eventually, a future simulation of maintenance processes. This module will serve as a decision support system, highlighting opportunities for improvement in maintenance processes.Originality/valueA practical guideline is provided for the future development of CMMSs and their enhancement to intelligence. All assumptions are based on maintenance theories, techniques for measuring maintenance performance and business process management and process mining.
目的精益智能维修等新的维修假设强调内部集成。由于维护过程没有与其他业务流程完全集成,这表明维护过程中的一些问题是由其他部门引起的。此外,如果不首先进行测量,任何事情都无法管理或改进。为了增强内部集成,本研究开发了一个模型,利用信息系统数据来检查参与维护操作的部门之间的同步和协作。设计/方法论/方法本研究通过信息系统将维护管理和业务流程管理联系起来。提出了一个基于CMMS的概念模块模型,该模型将使用CMMS中已经可用的数据,并使用过程挖掘来评估组织内各部门之间的同步水平。发现此概念模型将作为创建更好的增值CMMS软件的路线图。该系统作为三个专业的绩效衡量工具运行,包括组织分析、工作流程分析,以及最终的维护过程模拟。该模块将作为一个决策支持系统,突出维护流程改进的机会。独创性/价值为CMM的未来发展及其智能化提供了实用指南。所有假设都基于维护理论、测量维护性能的技术以及业务流程管理和流程挖掘。

PurposeThe study aims to design the limited number of random working cycle as a warranty term and propose two types of warranties, which can help manufacturers to ensure the product reliability during the warranty period. By extending the proposed warranty to the consumer's post-warranty maintenance model, besides the authors investigate two kinds of random maintenance policies to sustain the post-warranty reliability, i.e. random replacement first and random replacement last. By integrating depreciation expense depending on working time, the cost rate is constructed for each random maintenance policy and some special cases are provided by discussing parameters in cost rates. Finally, sensitivities on both the proposed warranty and random maintenance policies are analyzed in numerical experiments.Design/methodology/approachThe working cycle of products can be monitored by advanced sensors and measuring technologies. By monitoring the working cycle, manufacturers can design warranty policies to ensure product reliability performance and consumers can model the post-warranty maintenance to sustain the post-warranty reliability. In this article, the authors design a limited number of random working cycles as a warranty term and propose two types of warranties, which can help manufacturers to ensure the product reliability performance during the warranty period. By extending a proposed warranty to the consumer's post-warranty maintenance model, the authors investigate two kinds of random replacement policies to sustain the post-warranty reliability, i.e. random replacement first and random replacement last. By integrating a depreciation expense depending on working time, the cost rate is constructed for each random replacement and some special cases are provided by discussing parameters in the cost rate. Finally, sensitivities to both the proposed warranties and random replacements are analyzed in numerical experiments.FindingsIt is shown that the manufacturer can control the warranty cost by limiting number of random working cycle. For the consumer, when the number of random working cycle is designed as a greater warranty limit, the cost rate can be reduced while the post-warranty period can't be lengthened.Originality/valueThe contribution of this article can be highlighted in two key aspects: (1) the authors investigate early warranties to ensure reliability performance of the product which executes successively projects at random working cycles; (2) by integrating random working cycles into the post-warranty period, the authors is the first to investigate random maintenance policy to sustain the post-warranty reliability from the consumer's perspective, which seldom appears in the existing literature.
目的本研究旨在设计有限数量的随机工作周期作为保修期,并提出两种类型的保修,以帮助制造商确保产品在保修期内的可靠性。通过将建议的保修扩展到消费者的保修后维护模型,此外,作者还研究了两种维持保修后可靠性的随机维护策略,即先随机更换和后随机更换。通过整合取决于工作时间的折旧费用,为每个随机维护策略构建了成本率,并通过讨论成本率中的参数提供了一些特殊情况。最后,在数值实验中分析了所提出的保修和随机维护策略的敏感性。设计/方法/途径产品的工作周期可以通过先进的传感器和测量技术进行监测。通过监测工作周期,制造商可以设计保修政策以确保产品的可靠性性能,消费者可以对保修后维护进行建模以维持保修后的可靠性。在本文中,作者设计了有限数量的随机工作周期作为保修期,并提出了两种类型的保修,这可以帮助制造商确保产品在保修期内的可靠性性能。通过将拟议保修扩展到消费者的保修后维护模型,作者研究了两种维持保修后可靠性的随机更换策略,即先随机更换和后随机更换。通过整合取决于工作时间的折旧费用,构建了每次随机更换的成本率,并通过讨论成本率中的参数提供了一些特殊情况。最后,在数值实验中分析了对所提出的保证和随机替换的敏感性。结果表明,制造商可以通过限制随机工作周期的数量来控制保修成本。对于消费者来说,当随机工作周期的数量被设计为更大的保修限额时,成本率可以降低,而保修期后的时间不能延长。原创性/价值本文的贡献可以突出在两个关键方面:(1)作者调查了早期保修,以确保在随机工作周期内连续执行项目的产品的可靠性性能;(2) 通过将随机工作周期纳入保修期,作者首次从消费者的角度研究了随机维护策略,以维持保修期后的可靠性,这在现有文献中很少出现。

PurposeThe purpose of this paper is to support total productive maintenance implementers by providing a roadmap for autonomous maintenance (AM) preparation phase.Design/methodology/approachThe authors use the axiomatic design (AD) methodology with lean philosophy as a paradigm.FindingsThis is an exploratory research to find the most important factors in AM preparation phase. A decoupled AD design ensures an effective usage of training within industry (TWI) and the introduction of standardized work (SW). TWI provides value in importance it assigns to leaders, with its “train the trainers” approach and in preparing a training program. Besides being an effective training method, TWI job instruction (TWI JI) provides needed information infrastructure to front load operators SW and equipment trainings.Research limitations/implicationsAlthough AD, TWI and lean artifacts are generally field proven, the research is limited due to the lack of an industrial application.Practical implicationsIn many real-life projects, companies do not know where to start and how to proceed, which leads to costly iterations. The proposed roadmap minimizes iterations and increases the chance of project success.Originality/valueThe authors apply AD for the first time to AM preparation phase despite it is used in the analysis of lean manufacturing. AD permits to structure holistically the most relevant lean manufacturing solutions to obtain a risk free roadmap. TWI has emerged as a training infrastructure; TWI JI-based operator SW training and the adaptation of JI structure to equipment training are original additions.
目的本文的目的是通过提供自主维护(AM)准备阶段的路线图来支持全面生产性维护实施者。设计/方法论/方法论作者使用公理化设计(AD)方法论,以精益哲学为范式。发现这是一项探索性研究,旨在找出AM准备阶段最重要的因素。解耦的AD设计确保了行业内培训(TWI)的有效利用和标准化工作(SW)的引入。TWI通过其“培训培训师”的方法和准备培训计划,为领导者提供了重视的价值。TWI作业指导书(TWI JI)除了是一种有效的培训方法外,还为前端操作员软件和设备培训提供了所需的信息基础设施。研究局限性/含义尽管AD、TWI和精益工件通常经过现场验证,但由于缺乏工业应用,研究受到限制。实际含义在许多现实生活中的项目中,公司不知道从哪里开始以及如何进行,这导致了成本高昂的迭代。所提出的路线图最大限度地减少了迭代,并增加了项目成功的机会。独创性/价值作者首次将AD应用于AM准备阶段,尽管它用于精益制造的分析。AD允许全面构建最相关的精益制造解决方案,以获得无风险的路线图。TWI已成为一个培训基础设施;基于TWI JI的操作员软件培训和JI结构对设备培训的调整是最初的补充。

PurposeThis study aims to bring awareness to the developing of fault detection systems using the data collected from sensor devices/physical devices of various systems for predictive maintenance. Opportunities and challenges in developing anomaly detection algorithms for predictive maintenance and unexplored areas in this context are also discussed.Design/methodology/approachFor conducting a systematic review on the state-of-the-art algorithms in fault detection for predictive maintenance, review papers from the years 2017–2021 available in the Scopus database were selected. A total of 93 papers were chosen. They are classified under electrical and electronics, civil and constructions, automobile, production and mechanical. In addition to this, the paper provides a detailed discussion of various fault-detection algorithms that can be categorised under supervised, semi-supervised, unsupervised learning and traditional statistical method along with an analysis of various forms of anomalies prevalent across different sectors of industry.FindingsBased on the literature reviewed, seven propositions with a focus on the following areas are presented: need for a uniform framework while scaling the number of sensors; the need for identification of erroneous parameters; why there is a need for new algorithms based on unsupervised and semi-supervised learning; the importance of ensemble learning and data fusion algorithms; the necessity of automatic fault diagnostic systems; concerns about multiple fault detection; and cost-effective fault detection. These propositions shed light on the unsolved issues of predictive maintenance using fault detection algorithms. A novel architecture based on the methodologies and propositions gives more clarity for the reader to further explore in this area.Originality/valuePapers for this study were selected from the Scopus database for predictive maintenance in the field of fault detection. Review papers published in this area deal only with methods used to detect anomalies, whereas this paper attempts to establish a link between different industrial domains and the methods used in each industry that uses fault detection for predictive maintenance.

PurposeThis study aims to identify the relationship between different maintenance practices and productive efficiency in continuous process productive plants as well as the moderating effect of good training practices.Design/methodology/approachThe empirical data were drawn from a database containing 609 observations of 29 productive units. Scales were validated using the Q-sort method. The panel data technique was used as the analysis methodology, with the inclusion of fixed effects for each productive plant.FindingsMaintenance practices can effectively contribute to increasing the overall equipment effectiveness (OEE) of firms. Application of predictive maintenance practices should be considered as the primary training tool.Research limitations/implicationsThis study used a secondary database, limiting the research design and data manipulation.Practical implicationsThe article provides practitioners with an analysis of maintenance practices by category (predictive, preventive and corrective), and the impact of each practice on the OEE of continuous process productive plants. Moreover, it explores the importance of training for extracting more results from maintenance practices.Social implicationsCompanies are investing in new technologies, but it is also essential to invest in training people. There is a demand for Industry 4.0 through the introduction of upskilling and reskilling programs.Originality/valueThis study used practice-based view (PBV) theory to explain how maintenance practices help firms achieve greater OEE. Furthermore, it introduced training practice as a moderating variable in the relationship between maintenance practices and OEE.

PurposeIn this study, the focus was shifted from repairing durable goods to achieving healthier ecology, making durable goods more secure in turn. This study introduced preventive maintenance behavior to trace the ex-post control of “curling” back to the ex-post control of “self-healing.” This study tries to close the gap between the human repair of machines and their “self-curing.” Finally, the author makes the machines healthier.Design/methodology/approachThe paper constructed a mathematical model of preventive maintenance behavior during a specific period for durable consumer goods. The author builds a simulation function of the two-stage preventative maintenance behavior relations. The study used simulations to analyze the influencing relationship and differences between three preventive maintenance behavior elements to basic warranty preventive maintenance (BWPM) behavior and extended warranty preventive maintenance (EWPM) behavior.FindingsBoth BWPM behavior and EWPM behavior were affected by the preventive maintenance (PM) behavioral components in different ways. The influence paths of the two warranty periods affected by PM behavior were also different.Research limitations/implicationsThis study introduced PM behavior to trace the ex-post control of “curling” back to the ex-post control of “self-healing.” This study adopted the human–machine interaction mode to improve durable goods' self-healing ability during operation and enable a more effective and sustainable development.Practical implicationsThis study’s conclusions may help manufacturers guide PM behavior in a way that achieves “self-healing” of the durable goods.Originality/valueThe author opened a “black box” of PM behaviors and analyzed their components. The internal structure relation of PM behavior is built and the closed-loop system of spatial structure is formed.
目的在这项研究中,重点从修复耐用品转移到实现更健康的生态,从而使耐用品更安全。这项研究引入了预防性维修行为,将“卷曲”的事后控制追溯到“自我修复”的事前控制。这项研究试图缩小人类对机器的维修与“自我修复的”之间的差距。最终,作者使机器更健康。设计/方法论/方法本文构建了耐用消费品特定时期预防性维修行为的数学模型。建立了两阶段预防性维修行为关系的仿真函数。本研究通过仿真分析了三种预防性维修行为要素对基本保修预防性维修(BWPM)行为和延长保修预防性维护(EWPM)行为的影响关系和差异。发现预防性维护行为成分对BWPM行为和EWPM行为都有不同的影响。PM行为对两个保修期的影响路径也不同。研究局限性/含义本研究引入PM行为,将“卷曲”的事后控制追溯到“自我修复”的事前控制。本研究采用人机交互模式,提高耐用品在使用过程中的自我修复能力,实现更有效和可持续的发展。实际意义这项研究的结论可能有助于制造商指导PM行为,以实现耐用品的“自我修复”。原创/价值作者打开了一个PM行为的“黑匣子”,分析了它们的组成部分。建立了PM行为的内部结构关系,形成了空间结构的闭环系统。

The influence paths of the two warranty periods affected by PM behavior were also different.Research limitations/implicationsThis study introduced PM behavior to trace the ex-post control of “curling” back to the ex-post control of “self-healing.” This study adopted the human–machine interaction mode to improve durable goods' self-healing ability during operation and enable a more effective and sustainable development.Practical implicationsThis study’s conclusions may help manufacturers guide PM behavior in a way that achieves “self-healing” of the durable goods.Originality/valueThe author opened a “black box” of PM behaviors and analyzed their components. The internal structure relation of PM behavior is built and the closed-loop system of spatial structure is formed.","PeriodicalId":16938,"journal":{"name":"Journal of Quality in Maintenance Engineering","volume":" ","pages":""},"PeriodicalIF":1.5,"publicationDate":"2022-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48735849","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

PurposeIndustry decision makers often rely on a risk-based approach to perform inspection and maintenance planning. According to the Risk-Based Inspection and Maintenance Procedure project for the European industry, risk has two main components: probability of failure (PoF) and consequence of failure (CoF). As one of these risk drivers, a more accurate estimation of the PoF will contribute to a more accurate risk assessment. Current methods to estimate the PoF are either time-based or founded on expert judgement. This paper suggests an approach that incorporates the proportional hazards model (PHM), which is a statistical procedure to estimate the risk of failure for a component subject to condition monitoring, into the risk-based inspection (RBI) methodology, so that the PoF estimation is enhanced to optimize inspection policies.Design/methodology/approachTo achieve the overall goal of this paper, a case study applying the PHM to determine the PoF for the real-time condition data component is discussed. Due to a lack of published data for risk assessment at this stage of the research, the case study considered here uses failure data obtained from the simple but readily available Intelligent Maintenance Systems bearing data, to illustrate the methodology.FindingsThe benefit of incorporating PHM into the RBI approach is that PHM uses real-time condition data, allowing dynamic decision-making on inspection and maintenance planning. An additional advantage of the PHM is that where traditional techniques might not give an accurate estimation of the remaining useful life to plan inspection, the PHM method has the ability to consider the condition as well as the age of the component.Research limitations/implicationsThis paper is proposing the development of an approach to incorporate the PHM into an RBI methodology using bearing data to illustrate the methodology. The CoF estimation is not addressed in this paper.Originality/valueThis paper presents the benefits related to the use of PHM as an approach to optimize the PoF estimation, which drives to the optimal risk assessment, in comparison to the time-based approach.
行业决策者通常依靠基于风险的方法来执行检查和维护计划。根据欧洲工业基于风险的检查和维护程序项目,风险有两个主要组成部分:故障概率(PoF)和故障后果(CoF)。作为这些风险驱动因素之一,对PoF的更准确的估计将有助于更准确的风险评估。目前估计PoF的方法要么是基于时间的,要么是基于专家判断的。本文提出了一种方法,将比例风险模型(PHM)——一种估计状态监测部件失效风险的统计方法——纳入基于风险的检测方法中,从而增强PoF估计以优化检测策略。为了实现本文的总体目标,本文讨论了一个应用PHM确定实时状态数据组件的PoF的案例研究。由于在研究的这个阶段缺乏公开的风险评估数据,这里考虑的案例研究使用从简单但容易获得的智能维护系统轴承数据中获得的故障数据来说明方法。将PHM纳入RBI方法的好处是PHM使用实时状态数据,允许对检查和维护计划进行动态决策。PHM的另一个优点是,传统技术可能无法给出剩余使用寿命的准确估计来计划检查,而PHM方法能够考虑组件的条件和年龄。研究限制/影响本文提出了一种方法的发展,将PHM纳入RBI方法,使用轴承数据来说明该方法。本文没有讨论CoF估计问题。原创性/价值本文介绍了与使用PHM作为优化PoF估计的方法相关的好处,与基于时间的方法相比,PHM可以驱动最佳风险评估。

PurposeThe proposed hybridized framework provides a new performance optimization-based paradigm for analysing the failure behaviour of paneer unit (PU) in the dairy industry.Design/methodology/approachA novel fuzzy Jaya-based Lambda–Tau Optimization (JBLTO) approach-based mathematical modelling was developed for calculating various reliability indices of the considered unit. Failure mode and effect analysis (FMEA) was carried using qualitative information gathered from system's expert opinions. Fuzzy-complex proportional assessment (FCOPRAS) approach was integrated within FMEA to recognize the most critical failure causes associated with various subsystem/components.FindingsThe availability of the unit falls by 0.053% as the uncertainty level increases from ±15 to ±25% and further decreases to 0.323% as the uncertainty level increases from ±25 to ±60%. Failure causes, namely wearing in gears of gearbox (MST4), an impeller's cavitation and/or corrosion (CFP4), winding failure of electric motor (WS9), were recognized as the most critical failure causes with FCOPRAS final performance scores of 100, 100 and 100 and fuzzy combinative distance-based assessment (FCODAS) resultant assessment score of 0.5997, 1.1898 and 1.6135.Originality/valueJBLTO approach-based reliability results were compared with traditional particle swarm optimization-based Lambda–Tau (PSOBLT) and traditional fuzzy Lambda–Tau (FLT) approaches for confirming the downward trend in the system's availability. The ranking results of qualitative analysis are compared with the implementation of FCODAS technique. Sensitivity analysis was executed to evaluate the robustness of the proposed hybridized framework.
目的提出的混合框架为分析奶业中奶牛厂机组(PU)的失效行为提供了一种新的基于性能优化的范式。设计/方法/方法提出了一种新的基于模糊jaya的Lambda-Tau优化(JBLTO)方法的数学模型,用于计算考虑单元的各种可靠性指标。利用从系统专家意见中收集的定性信息进行故障模式和影响分析(FMEA)。在FMEA中集成了模糊-复杂比例评估(FCOPRAS)方法,以识别与各个子系统/组件相关的最关键故障原因。当不确定度从±15%增加到±25%时,该装置的可用性下降0.053%,当不确定度从±25%增加到±60%时,该装置的可用性进一步下降至0.323%。FCOPRAS最终性能得分分别为100分、100分和100分,模糊组合距离评价(FCODAS)综合评价得分分别为0.5997、1.1898和1.6135,结果表明,齿轮箱齿轮磨损(MST4)、叶轮空化和/或腐蚀(CFP4)、电动机绕组失效(WS9)是最关键的失效原因。将基于独创性/valueJBLTO方法的可靠性结果与传统的基于粒子群优化的Lambda-Tau (PSOBLT)方法和传统的模糊Lambda-Tau (FLT)方法进行比较,以确定系统可用性的下降趋势。将定性分析的排序结果与FCODAS技术的实施结果进行了比较。采用敏感性分析来评价所提出的杂交框架的鲁棒性。

PurposeThe data created from regular maintenance activities of equipment are stored as text in industrial plants. The size of these data is increasing rapidly nowadays. Text mining provides a chance to handle this huge amount of text data and extract meaningful information to improve various processes of an industrial environment. This paper represents the application of classification models on maintenance text records to classify failure for improving maintenance programs in the industry.Design/methodology/approachThis paper is presented as an implementation study, where text mining approaches are used for binary classification of text data. Naive Bayes and Support Vector Machine (SVM), two classification algorithms are applied for training and testing of the models as per the labeled data. The reason behind this is, these algorithms perform better on text data for classifying failure and they are easy to handle. A methodology is proposed for the development of maintenance programs, including classification of potential failure in advance by analyzing the regular maintenance data as well as comparing the performance of both models on the data.FindingsThe accuracy of both models falls within the acceptable limit, and performance evaluation of the models concludes the validation of the results. Other performance measures exhibit excellent values for both of the models.Practical implicationsThe proposed approach provides the maintenance team an opportunity to know about the upcoming breakdown in advance so that necessary measures can be taken to prevent failure in an industrial environment. As predictive maintenance incurs a high expense, it could be a better replacement for small and medium industrial plants.Originality/valueNowadays, maintenance is preventive-based rather than a corrective approach. The proposed technique is facilitating the concept of a proactive approach by minimizing the cost of additional maintenance steps. As predictive maintenance is efficient but incurs high expenses, this proposed method can minimize unnecessary maintenance operations and keep control over the budget. This is a significant way of developing maintenance programs and will make maintenance personnel ready for the machine breakdown.
