Abstract

Previous research has not analyzed the helium temperature distribution in the RDE steam generator shell. This study aims to fill that gap by analyzing these thermal characteristics with empirical calculations and Ansys Fluent simulations. The validity of the RDE steam generator design is reaffirmed, having been successfully analyzed from both the water-flow perspective in previous research and the helium-side perspective in the present study. The analytical methods used herein showed strong consistency, with empirical and numerical simulation results differing by less than 10% across all parameters. Although the calculated shell height of 5.73 m exceeds the RDE design's 4.97 m, the overall design's validity is confirmed.

Abstract

Overall Equipment Effectiveness (OEE) is a comprehensive measure to identify the level of productivity and performance of machines/equipments. Conventional approaches to OEE data processing, such as using Microsoft Excel, have limitations. Consequently, the data processing process becomes less efficient and prone to human error. This study aims to examine the application of OEE in the Manufacturing Industry, measurable performance gaps between conventional and real-time approaches. The methodology used in this study was based on a synthetic literature review to evaluate the effectiveness of both OEE approaches based on existing studies. The transition of OEE from mere calculations to dynamic, real-time, and integrated systems is a direct response to the increasing complexity and competitiveness of the modern manufacturing environment. This study can be used to identify areas for future development and as a reference for further research to provide a guide to OEE practitioners in implementing improvements.
