- Description: Routine maintenances are useful for reducing downtimes of rides in theme parks. Breakdown maintenances impact on the maintenance budget and customer experience and there is a possibility to minimize the unnecessary down time with the right decision on maintenance and replacements. Gyro swing is one of the oldest rides in the park studied in this paper. It will complete the 20 years of service life by 2024. Organization will have to allocate significant time, cost, and manpower for annual maintenance, shutdown for twenty-year overhaul or replacement. Cost for overhaul is estimated close to 2.23M AUD for the components, manpower, spare and services and 3.42M AUD for a replacement. This paper is on analysis and findings from a study conducted to evaluate the feasible economic decision on whether to overhaul or replace. © 2022 IEEE.

- Description: Technological changes have been happening in production facilities including food manufacturing industries in an ever-increasing rate. This includes advancement in data capture devices, signal processing, communication capabilities and automated process control systems such as Internet of Things. It is more challenging where production systems are highly reliant on automation and robotics. Remote performance monitoring and controls are becoming progressively vulnerable due to risks associated with cyber security and corporate espionage. May 2021 cyber-Attack forced JBS meats USA to pay 11m in ransom money to stop any further disruptions in services. This heavily impacted JBS global operations including JBS Australian food manufacturing facilities. Food production facilities in Australia have critical control points supported by smart technologies as part of their food safety management systems. Cyber-Attacks on production facilities could result in financial, operational, health and safety consequences. As survey by the Australian Cyber Security Centre in 2020 revealed that Australian small businesses are impacted by cybercime each year with a loss of 300m. To present the potential cyber security threats and their associated risk level, a case study is presented based on the processing and manufacture of meat products in Australia. From this case study, to protect the meat industries from attacks, we identify cyber security attacks and their possible mitigation strategies. This research shows cyber security attacks can severely affect Overall Equipment Effectiveness which motivate us to embed cyber security as an additional pillar in existing 8 pillars Total Productive Maintenance. If cyber security is added as additional pillar, it will improve the quality of end products and overall productivity of manufacturing industries. © 2021 IEEE.

- Description: Fluctuating demands and increased competition in Australia and Asian countries have been putting more pressure on plants for packaged meat products in Australia. Total Productive Maintenance (TPM) was seen a solution and is currently being implemented within a major meat processing facility in Melbourne, Australia for achieving high Overall Equipment Effectiveness (OEE). Concerns were raised by board of directors due to OEE targets not meant. TPM was initially applied in key areas of the business, thermoforming and packaging for reducing wastes and further enhancing productivity and quality. It is now being rolled out to other sections of the plant. Data collected from fifty-two weeks of production has been analysed and recommendations made to achieve OEE targets for the R145 production line. Risk based maintenance was applied to control adverse effects of packaging quality which significantly influences shelf life. Shelf life of a modified atmosphere packaged product assures safety for consumption of meat products by consumers. Risk based maintenance considered asset failure probabilities, impacts on quality and availability of spare parts. Reliability Centred Maintenance (RCM) resulted in a Risk score for each maintenance activity and as a component was used for TPM program. Findings from this study have been passed on to the meat processing facility for implementation in the entire plant.

- Description: Remote asset management are faced with additional challenges in monitoring conditions, coordinating logistics for maintenance crew, transport and spare parts for maintenance delivery and asset replacements. Recent trends in technologies, remote performance monitoring and risk-based decision making in Capital Expenditure (CAPEX) and Operations and Maintenance Expenditure (OPEX) decisions for asset management are being embraced by asset intensive industries around the world, where critical assets are located in geographically distributed remote areas or difficult to inspect and maintain locations. Industries are also pushing boundaries by reducing crew size, deferring capital expenditure and overhauling and decision making in inspection and in some cases relaxing Original Equipment Manufacturers (OEM) recommended maintenance schedules. This paper discusses some of the issues and challenges with remote asset management. Illustrative example from heavy haul rail is used to explain reduction in Life Cycle Costs (LCC) and further enhancing operational performance.

- Description: Overall Equipment Effectiveness (OEE) evaluates quantitatively how effectively a manufacturing operation is utilised. Total Productive Maintenance (TPM) was considered by Tibaldi, a leading food manufacturer in Australia for achieving OEE. This research project has identified performance gaps, developed plan and implemented it in Thermoforming area of the business. The developed methodology helped Tibaldi in improving productivity and quality through TPM involving machines, equipment, processes, and employees. This paper demonstrates how this can be achieved by reducing lead time and establishing lean environment. Productivity improvement through the devised methodology led to further enhancement of competitiveness of the organisation for domestic and international markets of processed food manufactured by Tibaldi Australia. Lessons learned from application of TPM in Thermoforming, a key asset area, is rolled out to other sections of the plat and results from this pilot study are presented in this paper.
