Evaluation of overall line effectiveness (OLE) in a continuous product line manufacturing system

Abstract

Purpose -The total productive maintenance concept provided a quantitative metric -overall equipment effectiveness (OEE), for measuring the effectiveness of individual equipment in a factory, which is significant but insufficient since world class manufacturing (WCM) system focus on product line involving machines in series. This paper aims to present an approach to measure the overall line effectiveness (OLE) in continuous line-manufacturing system. Design/methodology/approach -Systematic methodology, based on OEE metrics, is developed to model the productivity of a line manufacturing system in terms of OLE. The general and step-by-step method of OLE measurement in the line consisting of n number of processes is explained using a flow chart. Findings -Computer simulation has been carried out for the evaluation of OLE in product line manufacturing system with n number of machines. It also identifies the bottle-neck machines and the effect of specific contributing parameter for improvement. Practical implications -The result of this research makes it possible to represent the overall product line effectiveness as a benchmark for WCM to compare the performance of the various continuous product line manufacturing-based industries. Originality/value -This paper presents a successful and effective evaluation of OLE which will provide a useful guide to aspects of the production process where inefficiencies can be targeted for doing improvements in the product line.

Ethical and psychological factors in 5S and total productive maintenance

“…Kennedy and Mazza (2010) and Gajdzik (2009) were of the opinion that if employees have been sensitized to the benefits of the implementation of the 5S techniques, it would not only help in improving the overall working environment by making it safer and more comfortable, but it would also help in improving the motivation and morale of the employees; this, in turn, leads to increased eagerness of employees and their responsibilities towards correct implementation the TPM program pillars (Singh et al, 2013;Haddad & Jaaron, 2012), thereby improving the level of the overall production through the improvement the production lines effectiveness (OLE) (Nachiappan & Anantharaman, 2006;Nelson-Raja, Kannan & Jeyabalan, 2010). This stresses that the top management should provide the necessary financial and moral support for the performance of their tasks to raise the overall motivation of the employees (Pramod, 2007).…”

An analysis of managerial factors affecting the implementation and use of overall equipment effectiveness

“…To take better decisions to effectively and efficiently manage production systems, it is necessary for managers to establish appropriate metrics for measurement purposes (Nachiappan and Anantharam, 2006). Two of the most important and used metrics of performance in manufacturing operations are productivity and quality .…”

Practical Aspects of OEE in Automotive Company - Case Study

“…single machine, production line, entire company ( [11], [12], [13], [14], [15], [16], [17], [18], [19], [20]),  Specific characteristics of an industry ( [21], [22], [23], [24], [25]). Although OEE originated as a part of TPM, it has also been used extensively outside the maintenance paradigm [19].…”
