Abstract
This paper proposes a new index for a comprehensive and systematic measurement of sustainability and throughput performance in production systems. The proposed index, called Sustainable Overall Throughput Effectiveness (S.O.T.E.), is designed on the basis of a comparison of the environmental and operational factors. Specifically, it integrates the following four dimensions: availability, utilization, performance, and environmental sustainability. The way each dimension is measured is explained and justified. This index uses the overall environmental equipment effectiveness (OEEE) index, which is based on the Overall Equipment Effectiveness (OEE) index. However, such metrics are lacking at the factory level, because OEEE, as well as the OEE, is devoted to equipment-level. Its application and potential contribution to the analysis of sustainable throughput is demonstrated through a case study in an actual crushing plant. Through examining several hypotheses concerning the relationship between operational and environmental performance, a series of useful conclusions could be raised. The main difference and advantage of the proposed S.O.T.E. is that S.O.T.E., as it is based on the Overall Throughput Effectiveness (OTE), measures factory-level sustainability and operational performance. S.O.T.E. allows us to relate the impact of the overall effectiveness of each one of the components of the index to each piece of equipment that makes a part of the production systems. Furthermore, S.O.T.E., as OTE, take into account the production system configuration (series, parallel, assembly, etc.).
Highlights
Since the 1980s, Overall Equipment Effectiveness (OEE) has been recognized as a fundamental indicator for measuring performance at the level of equipment [1]
The main difference and advantage of the proposed S.O.T.E. is that S.O.T.E., as it is based on the Overall Throughput Effectiveness (OTE), measures factory-level sustainability and operational performance
To allow the evaluation of the effectiveness at the production system level and of the impact of each one of the equipment’s operational parameters, we propose the substitution of the OEE, in each one of the models proposed by Muthiah and Huang [5], with the overall environmental equipment effectiveness (OEEE) metric, proposed by Domingo and Aguado [13] (Equation (4))
Summary
Since the 1980s, Overall Equipment Effectiveness (OEE) has been recognized as a fundamental indicator for measuring performance at the level of equipment [1]. SMM takes chosen sustainability indicators into consideration and is based on VSM, Life Cycle Assessment (LCA), and Discrete Event Simulation (DES). The triple bottom line (TBL) has become a very useful concept to measure sustainability according to three main attributes, namely, environment, economy, and society. Those attributes have been identified as core pillars of sustainability. Several works have used the TBL concept as an attempt to measure the sustainability of different kinds of organizations, processes, and products. Mahmood et al [19] established a relationship among the traditional OEE factors (availability, productivity, and quality) and sustainability (through the use of the TPL concept). The author suggests mechanisms to embed sustainability attribute into business operational management systems, such as Material Requirement Planning (MRP), Manufacturing Execution Systems (MES), and Enterprise Resource Planning (ERPs) software
