Maintenance is an important process in a manufacturing system. Thus it should be conducted and measured effectively to ensure performance efficiency. A variety of studies have been conducted on maintenance as affected by factors such as productivity, cost, employee skills, resource utilisation, equipment, processes, and maintenance task planning and scheduling [1,2]. According to Coetzee [3], equipment is the most significant factor affecting maintenance performance because it is directly influenced by maintenance activities. This paper proposes an equipment performance and reliability (EPR) model for measuring maintenance performance based on machine effectiveness. The model is developed in four phases, using Pareto analysis for machine selection, and failure mode and effect analysis (FMEA) for failure analysis processes. Machine effectiveness is measured using the integration of overall equipment effectiveness and the reliability principle. The result is interpreted in terms of maintenance effectiveness, using five health index levels as bases. The model is implemented in a semiconductor company, and the outcomes confirm the practicality of the EPR model as it helps companies to measure maintenance effectiveness.

Specific results of effects of investment activities are expressed through effectiveness and reliability of a production process, or business system operations. Investment activities are implemented and verified through a certain decision-making matrix-the model of influence. Corrective effect of implementation of investment activities on effectiveness of real industrial system is shown by the research of operational readiness and reliability of the paper machine real system. Positive movements resulting from the raising of overall efficiency of industrial plant which are expressed by the change of operational readiness and reliability, and thus by higher performance per hour, are the confirmation and justification of investments in new technical solutions. Operational readiness and reliability of a real industrial system are analysed for two equal monitoring periods immediately before and after implementation of corrective measures i.e. investment activities, i.e. from the term of general overhaul of the paper machine.

This article discusses how to improve the overall equipment effectiveness (OEE) of the chicken bowl printing machine. OEE is important to measure machine performance in the production process. OEE will affect the costs incurred during production activities, such as product defects, how effective the performance of machines is, and how much time is available for production. The failure-tags analysis was used to identify the category factors causing engine failure. The why-why analysis was used to identify the root cause of the problem, and the theory of change was used to explain what should be implemented by the company to improve the OEE value. In 2020, only December had a value above standard by 95%, based on the Seiichi Nakajima OEE has a good value if the value >85%. The OEE values From January to May were fell from 73% to 34% and then kept increasing to 73% in November. The increase of the OEE value can be achieved by implementing a communication schedule, monitoring and eva...
Total productive maintenance is practical technique aimed at maximizing the effectiveness of facility that we use within our organization. Total productive maintenance establishes a system of productive maintenance, covering the entire life cycle of equipment, covers all departments, involves participation of all employees from top to bottom and promotes small group autonomous activities. During high growth era companies make technical progress in automation and centralization of the plants, which needs large amount of manual work to maintain the automation systems. The strategy of maintaining the equipment of a plant is crucial for the effectiveness of manufacturing. And, as the competitive environment in the world continues to increase the pace, our project work intends to help companies to develop new strategies to reduce costs, develop employees to face future challenges and bring about a new culture at work place. To carry out successful implementation of our work, firstly, literature review was done thoroughly to understand the underlying concepts of TPM. Further, empirical study was conducted based on real time data and analysis was done to obtain achievable results. Finally questionnaires were distributed to assess information on successful implementa-tion of TPM in the industry. Results obtained through the empirical study revealed the varying trends in the Overall Equipment Effectiveness (OEE) and Total Productivity of the machines taken up for the study. The average values of OEE were found to lay between the ranges of 63% to 71% against world class standards of 85%. The results highlighted the major causes resulting in the downtime and decrease in the productivity. A comparative study between World Class industries where TPM has been implemented and industries which do not follow TPM identifies the various problems leading to decrease in the overall efficiency of the industry and provides valuable suggestions focusing on the benefits and methodology for implementing TPM in industries. Total productive maintenance has proved the capacity for helping companies set up their operations through outlining feasible aims and objectives, structures and guidelines. These improve the production of companies, increase their market share and help them achieve high performance using minimum costs. Companies that have used TPM have realized immense performance growth levels.

Quantification of machine performance through Overall Equipment Effectiveness
2015 International Symposium on Technology Management and Emerging Technologies (ISTMET), 2015
Overall Equipment Effectiveness (OEE) is a hierarchy of metrics to measure the production machine performance in manufacturing industry. OEE measurement is inspired by the Total Productive Maintenance (TPM) and used as a key machine performance tool which measures availability, performance and quality rate. This study was conducted in a manufacturing company producing a broad range of packaging products. The main issue found relating to machine productivity was where availability shows a significant decrease since the purchase date.. Thus, data were collected for 12 months from the corrugator's machine and analysed using Microsoft Excel Software to determine the value of the output table, and presented graphically. The results of this study revealed that availability achieved an improvement of 5 per cent over the world standard OEE of 90 per cent, while the machine performance and quality rate each accounted for 10 per cent and 5 per cent decrease in the 'Ideal' value of OEE. Moreover, the comparisons with the 'Ideal' value of OEE were an indication level of total productivity improvement.
Maintenance Scheduling On Printing Machine Using The Duane Model
International Journal of Scientific & Technology Research, 2020
The important thing to ensure the success of operations is increasing reliability, which is achieved by maintaining machines and equipment. The Duane model is an approach in determining the MTBF (mean time between failure). The Duane model modifies the MTBF data into a logarithmic form. This paper chose the printing machine as the object of this study. The conventional method uses the MTBF data distribution pattern to obtain the average operating time. Using the Duane model and conventional method resulted a relatively small difference, 2.5 hours.

Maintenance performance level (MPL) is an important part of the key performance indicator (KPI) to improve the effectiveness of machine maintenance which includes factors of overall equipment effectiveness-machine effectiveness (OEE-ME) and machine reliability (MR). The purpose of this paper is to optimize the value of the maintenance performance level (MPL) through the collaboration of overall equipment effectiveness-machine effectiveness (OEE-ME) and machine reliability (MR). The study began with collecting research data, namely machine operation, preventive maintenance, and corrective maintenance. The data is processed using the Pareto principle to determine the critical system based on failure frequency. The selected critical system is tested for probability distribution and machine reliability (MR) assessment with several predetermined maintenance time interval scenarios. The main result of this research is the optimal maintenance time interval is a better criterion than other criteria. The optimal maintenance time interval was chosen because it can meet the requirements of overall equipment effectiveness-machine effectiveness (OEE-ME) at a world-class maintenance performance level (MPL) with a value of 90.43%, and the proposed machine reliability (MR) is better than the initial machine reliability (MR) based on the failure ratio value. Therefore, it can be boldly stated that the collaboration of overall equipment effectiveness-machine effectiveness (OEE-ME) and machine reliability (MR) can influence and optimize the value of maintenance performance level (MPL), which has a strong correlation and significant impact.
