In today's dynamic business environment, achieving and sustaining operational efficiency is paramount for organizations. To remain competitive and meet evolving customer demands, companies strive to optimize their operations and enhance efficiency. Over time, various indicators have been developed to assess efficiency across multiple operational dimensions, aligning with technological advancements and industrial practices. One such indicator is Overall Equipment Effectiveness (OEE), which evaluates equipment efficiency based on availability, performance, and quality. However, with the advent of the digital industry, the management of data for efficiency calculations has become increasingly complex. In this context, this paper proposes a digitized, real-time OEE calculation system that leverages advanced technologies to continuously monitor OEE, enable real-time decision-making, and drive performance improvements. Harnessing the potential of digitalization, the system facilitates seamless data collection, analysis, and reporting while automating manual processes. By focusing on OEE as a comprehensive efficiency indicator, the proposed system aims to enhance organizational performance and establish a foundation for calculating other efficiency measures.

In recent years, the increasing demand for autonomous vehicles in the mining industry has led to a greater focus on integrating these solutions with mine design. As technology advances, mining companies are looking to maximize the benefits of automation in terms of efficiency, productivity, and safety. The adoption of autonomous vehicles in mine design allows for the optimization of planning and operation of mining activities. Autonomous equipment can work continuously, reducing downtime and improving resource utilization. This has a direct impact on the overall equipment effectiveness (OEE), as availability and performance are significantly enhanced. In this research, the overall equipment effectiveness (OEE) of an Autonomous Haulage System (AHS) and its impact on the design of an open-pit mine were evaluated at the engineering level in Chile. Additionally, a representative month of operation (January 2034) was modeled using discrete event simulation technique with current operation and AHS philosophies. The results of this model, which were validated and calibrated based on historical information, meetings with different work groups, and understanding of the engineering level of the study, indicate that the OEE of manual operation is 14.4% lower than that of AHS operation, demonstrating an opportunity for the implementation of this technology.

- Abstract
The performance of a production work center can be measured in the five dimensions speed, quality, flexibility, dependability, and cost. Existing approaches such as the Overall Equipment Effectiveness (OEE) are either not covering all objectives or give only limited support for full utilization of the increasing amounts of available data in production. This article introduces a hierarchical status classification system that allows the integration of versatile and detailed data streams based on time series. Based on the classifications, a detailed calculation and visualization of work center performance indicators is introduced to support the prioritization of countermeasures for work center's performance increase.

Nowadays, many water treatment plants face the problems of equipment breakdown and water loss during water production process. A method to solve these problems is to implement Eight pillars strategy (EPS), one of Total Productive Maintenance (TPM) strategy to reduce equipment breakdown, decrease water loss and enhance equipment effectiveness. Failure rate (FR), availability (A), performance efficiency (PE), quality rate (QR) were determined by evaluating equipment effectiveness through Overall Equipment Effectiveness (OEE). They were also evaluated to find the entire equipment/plant effectiveness through Net Equipment Effectiveness (NEE). In this study, the chlorinator machines in each couple phase 1&2 and 3&4 at Mahasawat Water Treatment Plant (MHS) were considered as a case study for practicing EPS. The reduction of FR and increase of A, PE and QR were revealed after practicing EPS to chlorinators as evidently evaluated in this paper. They affect to higher OEE and NEE in all couple phases. As a consequence, the chlorinators were able to operate continuously for longer time with high efficiency. The plant can also produce higher quantity of qualified water to customers by monitoring the final water treatment process via Profit Cost (PC). The proposed 17 steps for OEE, NEE and PC evaluations are shown in this paper might be a good approach for other water treatment plant to get higher chlorinator effectiveness and lower water loss.

Overall Equipment Effectiveness (OEE). Calculating plant/equipment OEE can be very helpful for monitoring trends (such as whether a given plant is improving OEE over time) or as a rough measure of where a given plant lies in the OEE benchmarking spectrum. OEE concept in TPM implementation truly reduces manufacturing complex problems into simple, intuitive presentation of information. It helps to systematically improve the process with easy-to-obtain measurements. The OEE is the process, which is acquired to specify an equivalent weight setting of every single element, even if, each concerning losses are totally different. Hence, the study proposes a weighted graph approach, to identify dissimilarity in weighting each OEE element. The proposed concept is used to find the OEE for the plant, as well as to set the target for the plant and the area to focus for their improvement. [ABSTRACT FROM AUTHOR]

- Abstract
The modern manufacturing shop floor contains a variety of different types of machining equipment, each supporting different proprietary interfaces and communication protocols. This diversity has made it extremely challenging for shop managers to monitor and maintain their machines. Fortunately, the emerging MTConnect standard makes it possible for a monitoring system to accurately and consistently collect data from any MTConnect compatible machine, regardless of its brand or origin. This paper introduces a web-based machine monitoring system that provides data collection, analysis, and machine event notification for MTConnect compatible machines. This solution provides shop managers with the information needed to improve process efficiency on the shop floor, and increase overall equipment effectiveness (OEE). [ABSTRACT FROM AUTHOR]

Industry is driven by efficiency, only this makes it possible to assert competitive advantage in the global market. Many companies use Overall Equipment Effectiveness (OEE) as a Key Performance Indicator (KPI). Currently the International Organization for Standardization (ISO) is working on standardized definitions of KPIs for Manufacturing Execution Systems (MES), based on VDMA 66412. The aim of this paper is to present a service oriented approach to OEE calculation based on ISO/DIS 22400-2 for CNC machines deployed in individual production using OPC Unified Architecture (OPC UA) as an information modelling and data transport technology. In contrast to conventional procedures for OEE calculation, where a huge amount of data is collected from shop floor level and analyzed at the supervisory level, we suggest that Key Performance Indicators are calculated as close as possible to the data sources.

- Abstract
Abstract: To compete in global market, no organization will tolerate losses. Overall Equipment Effectiveness (OEE) is such a performance measure metric which will indicate performance rate with very simple calculations. It considers all important measures of productivity. Implicitly it indicates amount of losses each parameter contributes to reduce productivity. By applying quality improvement tool such as failure Mode and Effect Analysis (FMEA) root cause of any OEE measure can be found out. It will help to improve OEE and correspondingly productivity.In this paper an attempt has been made to establish a relationship between OEE and FMEA. All the parameters of OEE (i.e. Availability, Performance Rate and Quality Rate) are evaluated with respective to FMEA (i.e. severity, occurrence and Detection). Total 32 hypothesis are considered to establish relation between OEE and FMEA. A case study conducted in one of reputed process industry gives very significant insight for OEE improvement. Power of Excel tool is explored in this paper. [Copyright &y& Elsevier]
