Several performance metrics to measure the effectiveness of manufacturing equipment have been studied, and one of the most used is overall equipment effectiveness (OEE). However, its application and development in the road transportation sector remains little studied. The purpose of this paper is to establish a new metric derived from OEE to measure the overall effectiveness of coal mining transportation and apply this metric to actual operation. This study employed in-depth interviews and Delphi techniques to explore the specific metrics. Three rounds of Delphi involving mining experts, academia, and consultants identified six potential metrics to measure coal mining transportation operations that contributed to a new metric to measure mining transportation overall vehicle effectiveness. This paper also discusses a case study of how this newly developed metric was tested and applied to the actual operation of the truck fleet at a coal-hauling company in Indonesia. According to the case study, this metric accommodated the important factors in coal mining transportation operations and reflected operational performance. This study contributes to measuring the effectiveness of coal-hauling transportation by providing an effective metric that will help the managerial team make better decisions for process improvement.

Investing in a Dental Chair Unit is an investment that requires a large amount of funds for the hospital, therefore the utilization of a Dental Chair Unit tool is a concern for hospitals. The importance of Dental Chair Unit utilization leads hospital to calculate the effectiveness of Dental Chair Unit devices using the Overall Effectiveness Equipment (OEE) method. OEE measures the effectiveness of the tool based on the availability ratio, performance ratio and quality ratio. The aimed of this study was to analyze the effectiveness of Dental Chair Unit in Mother and Child Hospital using the OEE method. This research was conducted at the dental clinic of Mother and Child Hospital on February 2019. This study was a descriptive study that was to calculate the OEE from a Dental Chair Unit then analyze the causes of the effectiveness of the tools obtained. The results of the calculation of OEE Dental Chair Unit device in a Mother and Child Hospital at Surabaya are 18,7%, far below the standard of 85%. The cause of the low OEE value is the low value of the Performance ratio that is far below the standard 85%. The low performance ratio of Dental Chair Unit tools in mother and child hospital is caused by the small number of patients who come to the dental clinic, so a little also uses the Dental Chair Unit. It is because of the competition with general hospital that surround this hospital. Another factor that cause of low OEE ratio is patient's didn't know the importance of dental health for mother and children. [ABSTRACT FROM AUTHOR]
