AbstractPurpose -To evaluate the Cusum model as a means of rapid trend detection and dynamic response classifier in a low signal/noise environment. Design/methodology/approach -The method used was the design and implementation of an IT system for automatic on-line monitoring of press operator performance. Findings -Operators engaged following an in-house skills enhancement programme display a wide range of performance profiles. Research limitations/implications -Identifies opportunities for further management investigation of working practices identified as leading to regression plus operators obviously learning to "work smarter, not harder". Practical implications -A range of novel performance templates based on the Cusum model have been derived and tested on 18 press operators. Originality/value -The Cusum model is already well established in the literature. This case study shows that the model can be readily exploited via automatic operator performance monitoring and subsequent classification.

Improvement of Preventive Maintenance Plan for an Automatic Labeling System: A Case Study of a Carbonated Soft Drink Industry

“…Preventive maintenance planning is one of the most common and significant problems faced by the manufacturing industry [1]. Without appropriate preventive maintenance plan, the breakdown became more frequent [2]. The objective of a preventive maintenance plan is to improve the reliability of the equipment and enhance their performance [3], [4] in which a well-defined set of tasks (e.g., inspection, repair, replacement, cleaning, lubrication, adjustment and alignment) is planned to be performed [5].…”
