PurposeWith production systems become more digitized, data-driven maintenance decisions can improve the performance of production systems. While manufacturers are introducing predictive maintenance and maintenance reporting to increase maintenance operation efficiency, operational data may also be used to improve maintenance management. Research on the value of data-driven decision support to foster increased internal integration of maintenance with related functions is less explored. This paper explores the potential for further development of solutions for cross-functional responsibilities that maintenance shares with production and logistics through data-driven approaches.Design/methodology/approachFifteen maintenance experts were interviewed in semi-structured interviews. The interview questions were derived based on topics identified through a structured literature analysis of 126 papers.FindingsThe main findings show that data-driven decision-making can support maintenance, asset, production and material planning to coordinate and collaborate on cross-functional responsibilities. While solutions for maintenance planning and scheduling have been explored for various operational conditions, collaborative solutions for maintenance, production and logistics offer the potential for further development. Enablers for data-driven collaboration are the internal synchronization and central definition of goals, harmonization of information systems and information visualization for decision-making.Originality/valueThis paper outlines future research directions for data-driven decision-making in maintenance management as well as the practical requirements for implementation.
目的随着生产系统日益数字化,数据驱动的维护决策可以提高生产系统的性能。制造商们正在引入预测性维护和维护报告来提高维护操作效率,而操作数据也可用于改善维护管理。关于数据驱动的决策支持对促进维护与相关功能进一步内部整合的价值的研究较少。本文探讨了通过数据驱动方法进一步开发维护与生产和物流共同承担的跨职能责任解决方案的潜力。访谈问题是根据对 126 篇论文进行结构化文献分析后确定的主题而提出的。研究结果主要研究结果表明,数据驱动决策可以支持维护、资产、生产和材料计划在跨职能职责方面进行协调与合作。虽然已经针对各种运行条件探索了维护规划和调度的解决方案,但维护、生产和物流的协作解决方案仍有进一步发展的潜力。数据驱动协作的推动因素包括内部同步和目标的集中定义、信息系统的协调以及决策信息的可视化。

PurposeThis research integrates maintenance planning and production scheduling from a green perspective to reduce the carbon footprint.Design/methodology/approachA mixed-integer nonlinear programming (MINLP) model is developed to study the relation between production makespan, energy consumption, maintenance actions and footprint, i.e. service level and sustainability measures. The speed scaling technique is used to control energy consumption, the capping policy is used to control CO2 footprint and preventive maintenance (PM) is used to keep the machine working in healthy conditions.FindingsIt was found that ignoring maintenance activities increases the schedule makespan by more than 21.80%, the total maintenance time required to keep the machine healthy by up to 75.33% and the CO2 footprint by 15%.Research limitations/implicationsThe proposed optimization model can simultaneously be used for maintenance planning, job scheduling and footprint minimization. Furthermore, it can be extended to consider other maintenance activities and production configurations, e.g. flow shop or job shop scheduling.Practical implicationsMaintenance planning, production scheduling and greenhouse gas (GHG) emissions are intertwined in the industry. The proposed model enhances the performance of the maintenance and production systems. Furthermore, it shows the value of conducting maintenance activities on the machine's availability and CO2 footprint.Originality/valueThis work contributes to the literature by combining maintenance planning, single-machine scheduling and environmental aspects in an integrated MINLP model. In addition, the model considers several practical features, such as machine-aging rate, speed scaling technique to control emissions, minimal repair (MR) and PM.

PurposeThe purpose of this study is to propose a new mathematical model that integrates strategic decision-making with tactical-operational decision-making in order to optimize production and scheduling decisions.Design/methodology/approachThis study presents a multi-objective optimization framework to make production planning, scheduling and maintenance decisions. An epsilon-constraint method is used to solve small instances of the model, while new hybrid optimization algorithms, including multi-objective particle swarm optimization (MOPSO), non-dominated sorting genetic algorithm, multi-objective harmony search and improved multi-objective harmony search (IMOHS) are developed to address the high complexity of large-scale problems.FindingsThe computational results demonstrate that the metaheuristic algorithms are effective in obtaining economic solutions within a reasonable computational time. In particular, the results show that the IMOHS algorithm is able to provide optimal Pareto solutions for the proposed model compared to the other three algorithms.Originality/valueThis study presents a new mathematical model that simultaneously determines green production planning and scheduling decisions by minimizing the sum of the total cost, makespan, lateness and energy consumption criteria. Integrating production and scheduling of a shop floor is critical for achieving optimal operational performance in production planning. To the best of the authors' knowledge, the integration of production planning and maintenance has not been adequately addressed.

Purpose It is well known in the mining industry that the increase in failures and breakdowns is due mainly to a poor maintenance policy for the equipment, in addition to the difficult access that specialized personnel have to combat the breakdown, which translates into more machine downtime. For this reason, this study aims to propose a remote assistance model for diagnosing and repairing critical breakdowns in mining industry trucks using augmented reality techniques and data analytics with a quality approach that considerably reduces response times, thus optimizing human resources. Design/methodology/approach In this work, the six-phase CRIPS-DM methodology is used. Initially, the problem of fault diagnosis in trucks used in the extraction of material in the mining industry is addressed. The authors then propose a model under study that seeks a real-time connection between a service technician attending the truck at the mine site and a specialist located at a remote location, considering the data transmission requirements and the machine's characterization. Findings It is considered that the theoretical results obtained in the development of this study are satisfactory from the business point of view since, in the first instance, it fulfills specific objectives related to the telecare process. On the other hand, from the data mining point of view, the results manage to comply with the theoretical aspects of the establishment of failure prediction models through the application of the CRISP-DM methodology. All of the above opens the possibility of developing prediction models through machine learning and establishing the best model for the objective of failure prediction. Originality/value The original contribution of this work is the proposal of the design of a remote assistance model for diagnosing and repairing critical failures in the mining industry, considering augmented reality and data analytics. Furthermore, the integration of remote assistance, the characterization of the CAEX, their maintenance information and the failure prediction models allow the establishment of a quality-based model since the database with which the learning machine will work is constantly updated.
在采矿业中,众所周知,故障和故障的增加主要是由于设备的维护政策不佳,此外,专业人员必须与故障作斗争,这意味着更多的机器停机时间。因此,本研究旨在提出一种远程辅助模型,用于诊断和修复采矿卡车的关键故障,该模型使用增强现实技术和数据分析,采用高质量的方法,大大缩短了响应时间,从而优化了人力资源。设计/方法/方法在这项工作中,使用了六阶段的CRIPS-DM方法。首先,对采矿业中用于物料提取的卡车的故障诊断问题进行了研究。然后,作者提出了一个正在研究的模型,该模型在考虑数据传输要求和机器特性的情况下,寻求在矿区现场负责卡车的服务技术人员和位于远程位置的专家之间的实时连接。研究结果认为,从商业的角度来看,在这项研究的发展中获得的理论结果是令人满意的,因为在第一个例子中,它实现了与远程医疗过程相关的具体目标。另一方面,从数据挖掘的角度来看,通过应用CRISP-DM方法,结果符合失效预测模型建立的理论方面。这些都为通过机器学习开发预测模型,建立最佳的故障预测模型提供了可能。这项工作的原始贡献是提出了一个远程辅助模型的设计,用于诊断和修复采矿业的关键故障,考虑到增强现实和数据分析。此外,远程协助、CAEX的特征、维护信息和故障预测模型的集成允许建立基于质量的模型,因为学习机器将使用的数据库不断更新。

Purpose It is of a great significance for the health monitoring of a liquid rocket engine to build an accurate and reliable fault prediction model. The thrust of a liquid rocket engine is an important indicator for its health monitoring. By predicting the changing value of the thrust, it can be judged whether the engine will fail at a certain time. However, the thrust is affected by various factors, and it is difficult to establish an accurate mathematical model. Thus, this study uses a mixture non-parametric regression prediction model to establish the model of the thrust for the health monitoring of a liquid rocket engine. Design/methodology/approach This study analyzes the characteristics of the least squares support vector regression (LS-SVR) machine . LS-SVR is suitable to model on the small samples and high dimensional data, but the performance of LS-SVR is greatly affected by its key parameters. Thus, this study implements the advanced intelligent algorithm, the real double-chain coding target gradient quantum genetic algorithm (DCQGA), to optimize these parameters, and the regression prediction model LSSVRDCQGA is proposed. Then the proposed model is used to model the thrust of a liquid rocket engine. Findings The simulation results show that: the average relative error (ARE) on the test samples is 0.37% when using LS-SVR, but it is 0.3186% when using LSSVRDCQGA on the same samples.

目的建立准确可靠的故障预测模型对液体火箭发动机的健康监测具有重要意义。液体火箭发动机的推力是其健康监测的重要指标。通过预测推力的变化值,可以判断发动机在某一时刻是否会发生故障。但推力受多种因素影响,难以建立精确的数学模型。因此,本研究采用混合非参数回归预测模型建立了用于液体火箭发动机健康监测的推力模型。设计/方法/方法本研究分析最小二乘支持向量回归(LS-SVR)机器的特点。LS-SVR适用于小样本和高维数据的建模,但LS-SVR的关键参数对其性能影响很大。为此,本研究采用先进的智能算法——实双链编码目标梯度量子遗传算法(DCQGA)对这些参数进行优化,并提出回归预测模型LSSVRDCQGA。然后将该模型应用于某液体火箭发动机的推力建模。仿真结果表明:使用LS-SVR对测试样本的平均相对误差(ARE)为0.37%,而使用LSSVRDCQGA对相同样本的平均相对误差为0.3186%。本文提出的LSSVRDCQGA模型对于小样本和多维数据的故障预测是有效的,具有一定的推广意义。本研究的原创性贡献在于建立了LSSVRDCQGA混合非参数回归预测模型,并利用LSSVRDCQGA对发动机推力进行建模,较好地解决了液体火箭发动机健康监测问题。

The thrust of a liquid rocket engine is an important indicator for its health monitoring. By predicting the changing value of the thrust, it can be judged whether the engine will fail at a certain time. However, the thrust is affected by various factors, and it is difficult to establish an accurate mathematical model. Thus, this study uses a mixture non-parametric regression prediction model to establish the model of the thrust for the health monitoring of a liquid rocket engine. Design/methodology/approach This study analyzes the characteristics of the least squares support vector regression (LS-SVR) machine . LS-SVR is suitable to model on the small samples and high dimensional data, but the performance of LS-SVR is greatly affected by its key parameters. Thus, this study implements the advanced intelligent algorithm, the real double-chain coding target gradient quantum genetic algorithm (DCQGA), to optimize these parameters, and the regression prediction model LSSVRDCQGA is proposed. Then the proposed model is used to model the thrust of a liquid rocket engine. Findings The simulation results show that: the average relative error (ARE) on the test samples is 0.37% when using LS-SVR, but it is 0.3186% when using LSSVRDCQGA on the same samples.

Design/methodology/approach This paper identifies and evaluates the factors accountable for the adoption of TPM methodology in manufacturing organizations. Twenty-four factors affecting the TPM implementation are explored and categorized into five significant categories. Afterwards, these identified TPM factors have been evaluated by using a most popular Multi-criteria decision-making (MCDM) approach namely fuzzy pivot pairwise relative criteria importance assessment (F-PIPRECIA). Findings In this paper, through application of F-PIPRECIA, “Behavioural factor” is ranked first while “Financial factor” the last. Considering the sub-factors, “Top management support and commitment” is ranked first while “Effective use of performance indices” is ranked the last. A further sensitivity analysis indicates the factors that need higher level of attention. Practical implications The result of current research work may be exploited by the top administration of manufacturing enterprises for assessing their TPM adoption status and to recognize the frail links of TPM application and improve accordingly. Moreover, significant factors of TPM can be identified and deploy them successfully in their implementation procedure. Originality/value The conclusion obtained from this research enables the management to clearly understand the significance of each considered factor on the adoption of TPM in the organization and hence, provides effective utilization of resources.

Purpose This paper aims to develop a dynamic civil facility degradation prediction model to forecast the reliability performance tendency and remaining useful life under imperfect maintenance based on the inspection records and the maintenance actions. Design/methodology/approach A real-time hidden Markov chain (HMM) model is proposed in this paper to predict the reliability performance tendency and remaining useful life under imperfect maintenance based on rare failure events. The model assumes a Poisson arrival pattern for facility failure events occurrence. HMM is further adopted to establish the transmission probabilities among stages. Finally, the simulation inference is conducted using Particle filter (PF) to estimate the most probable model parameters. Water seals at the spillway hydraulic gate in a Taiwan's reservoir are used to examine the appropriateness of the approach. Findings The results of defect probabilities tendency from the real-time HMM model are highly consistent with the real defect trend pattern of civil facilities. The proposed facility degradation prediction model can provide the maintenance division with early warning of potential failure to establish a proper proactive maintenance plan, even under the condition of rare defects. Originality/value This model is a new method of civil facility degradation prediction under imperfect maintenance, even with rare failure events. It overcomes several limitations of classical failure pattern prediction approaches and can reliably simulate the occurrence of rare defects under imperfect maintenance and the effect of inspection reliability caused by human error. Based on the degradation trend pattern prediction, effective maintenance management plans can be practically implemented to minimize the frequency of the occurrence and the consequence of civil facility failures.
目的建立民用设施劣化动态预测模型,根据检查记录和维修行为,预测不完全维修条件下民用设施的可靠性性能趋势和剩余使用寿命。设计/方法/方法提出了一种基于罕见故障事件的不完全维护情况下系统可靠性性能趋势和剩余使用寿命的实时隐马尔可夫链模型。该模型假定设施故障事件发生的泊松到达模式。进一步采用HMM建立阶段间的传输概率。最后,利用粒子滤波(PF)进行仿真推理,估计最可能的模型参数。台湾某水库溢洪道水闸的水封被用来检验该方法的适当性。结果实时HMM模型的缺陷概率趋势结果与民用设施的实际缺陷趋势模式高度吻合。提出的设施退化预测模型可以为维修部门提供潜在故障的早期预警,以便在罕见缺陷的情况下制定适当的主动维修计划。该模型是一种不完全维修条件下,即使故障事件很少,民用设施退化预测的新方法。该方法克服了传统失效模式预测方法的局限性,能够可靠地模拟不完全维修情况下罕见缺陷的发生和人为失误对检测可靠性的影响。基于退化趋势模式预测,可以在实际操作中实施有效的维护管理计划,以最大限度地降低民用设施故障的发生频率和后果。

Purpose This research aims to investigate critical success factors, barriers and initiatives of total productive maintenance (TPM) implementation in selected manufacturing industries in Addis Ababa, Ethiopia. Design/methodology/approach This study built and looked into a conceptual research framework. The potential barriers and success factors to TPM implementation have been highlighted. The primary study techniques used to collect relevant data were a closed-ended questionnaire and semi-structured interview questions. With the use of SPSS version 23 and SmartPLS 3.0 software, the data were examined using descriptive statistics and the inferential Partial Least Square Structural Equation Modeling (PLS-SEM) techniques. Findings According to the results of descriptive statistics and multivariate analysis using PLS-SEM, the case manufacturing industries' TPM implementation initiative is in its infancy; break down maintenance is the most widely used maintenance policy; top managers are not dedicated to the implementation of TPM; and there are TPM pillars that have been weakly and strongly addressed by the case manufacturing companies. Research limitations/implications The small sample size is a limitation to this study. It is therefore challenging to extrapolate the research findings to other industries. The only manufacturing KPI utilized in this study is overall equipment effectiveness (OEE). It is possible to add more parameters to the manufacturing performance measurement KPI. The relationships between TPM and other lean production methods may differ from those observed in this cross-sectional study. Longitudinal experimental studies and in-depth analyses of TPM implementations may shed further light on this. Practical implications Defining crucial success factors and barriers to TPM adoption, as well as identifying the weak and strong TPM pillars, will help companies in allocating their scarce resources exclusively to the most important areas. TPM is not a quick solution. It necessitates a change in both the company's and employees' attitude and their values, which takes time to bring about. Hence, it entails a long-term planning. The commitment of top managers is very important in the initiatives of TPM implementation. Originality/value This study is unique in that, it uses a new conceptual research model and the PLS-SEM technique to analyze relationships between TPM pillars and OEE in depth.
本研究旨在探讨埃塞俄比亚亚的斯亚贝巴选定制造业实施全面生产维护(TPM)的关键成功因素、障碍和举措。设计/方法/方法本研究建立并研究了一个概念性研究框架。强调了实施TPM的潜在障碍和成功因素。收集相关数据的主要研究方法是封闭式问卷和半结构化访谈问题。使用SPSS version 23和SmartPLS 3.0软件,采用描述性统计和推理偏最小二乘结构方程建模(PLS-SEM)技术对数据进行检验。运用PLS-SEM进行描述性统计和多变量分析的结果表明,案例制造业实施TPM的主动性处于起步阶段;故障维修是应用最广泛的维修策略;高层管理人员没有致力于TPM的实施;有一些TPM支柱已经被制造公司或弱或强地解决了。研究的局限性/启示小样本量是本研究的局限性。因此,将研究结果外推到其他行业是具有挑战性的。本研究中使用的唯一制造KPI是整体设备效率(OEE)。可以向制造性能度量KPI添加更多参数。TPM与其他精益生产方法之间的关系可能与本横断面研究中观察到的不同。对TPM实施的纵向实验研究和深入分析可能会进一步阐明这一点。确定采用TPM的关键成功因素和障碍,以及确定薄弱和强大的TPM支柱,将有助于公司将稀缺资源专门分配给最重要的领域。TPM不是一个快速的解决方案。它需要改变公司和员工的态度和价值观,这需要时间来实现。因此,它需要一个长期的计划。高层管理者的承诺在TPM实施的主动性中是非常重要的。独创性/价值本研究的独特之处在于,采用全新的概念研究模型和PLS-SEM技术,深入分析了TPM支柱与OEE之间的关系。
