“…The types of efficiency generated by the DEA were calculated: (1) standard efficiency; (2) inverted frontier; and 3composite efficiency. For this analysis, composite efficiency was used, which consisted of a mean between the DMUs with best and worst performances (Piran et al 2016(Piran et al , 2017Barbosa et al 2017;Souza et al 2018;Telles et al 2020). The inverted frontier of technical efficiency or IDEA evaluates the inefficiency of a DMU, constructing a frontier constituted of units with the worst managerial practices.…”

“…Production process Uses a sequence of combined individual measurements to determine the process performance after an integration of sub-processes more controllable than the outputs, which depend on market demand, for example (Telles et al 2020). In this case, the reduction of resources use in inefficient units is proposed.…”

The efficiency levels at which companies turn inputs into outputs may increase their competitive capacity. Nevertheless, in the literature, there is a lack of methods allowing evaluation of the performance of operations in production systems that take into account all of their components. The objective of this study is to present an analysis of efficiency for a production system using DEA and OEE in an integrated manner (DEA/OEE). To achieve this objective, we conducted a case study of a bus manufacturer and a comparative analysis using the results obtained by DEA/OEE compared with the results of the OEE measured in an operation of the company studied. The efficiency measured by DEA/OEE presents differences in relation to OEE results. The analysis of the causes of such differences pointed out that action taken to improve the OEE indicator decreased the efficiency of the operation analyzed. This study evidences that decision-making focused on improving OEE on its own may lead to an increase in the consumption of resources during an operation. Such an increase does not necessarily increase production levels and may reduce technical efficiency.

“…As a result of these ETO variations and characteristics, the work in process (WIP) and production availability at different production stages become unbalanced, requiring flexible processes (Bertrand and Muntslag, 1993). These characteristics make the adoption of DBR attractive for ETO firms (Telles et al, 2020). However, there are challenges to its implementation that need to be evaluated by managers.…”

“…These benefits can be obtained through adaptations undertaken to implement DBR in an ETO production system. However, existing studies in the literature do not detail what these adaptations are (Telles et al, 2020). The research question of this work is: What adaptations are necessary in the DBR method for its implementation in ETO production systems?…”

“…On the other hand, when this time is greater than 10% of the lead time, it is recommended to use other methods, such as critical chain project management (CCPM) (Cox and Schleier, 2010). Although the DBR assumption is not met in ETO environments, there is empirical evidence of the benefits provided by the implementation of DBR in an aerospace company (Telles et al, 2020). These benefits can be obtained through adaptations undertaken to implement DBR in an ETO production system.…”

PurposeDrum-Buffer-Rope (DBR) is a method to adjust production flows, synchronize the release of materials and enable a process of focused improvement in production systems. Literature on DBR applications in engineer-to-order (ETO) production systems, where customers participate in product design decisions and, consequently, in the way production is planned and executed, is rare. However, the interest in improving production management in ETO systems has received attention from the scientific and business communities. The goal of this research was to evaluate the implementation of DBR in an ETO productive system, critically analyzing the necessary adaptations for its use.Design/methodology/approachThis research was conducted through a case study in a company that manufactures electronic equipment, known as avionics, in the aerospace sector.FindingsIn this context, the contribution of this study consists of evaluation of the implementation of DBR in an ETO productive system, describing the implementation and the necessary adaptations of the DBR to the ETO productive system explored, comparing it with the DBR theoretical proposals and Simplified Drum-Buffer-Rope (S-DBR) methods.Originality/valueThe study contributes to knowledge by expanding the field of the DBR application to make it more precise, and by applying the theory of constraints, in a general manner, to this type of productive environment.
