“…The standard DEA method has been successfully applied for the evaluation of efficiencies where multiple inputs and outputs occur. 34 Based on this characteristic, researchers extend DEA to the field of ranking, such as cross-efficiency DEA ranking, super-efficiency DEA ranking, and benchmark DEA ranking. 35 This article applies super-efficiency DEA ranking method 36 for realizing IOR rank of PPs, and the method can be described as below min 1 + 1 m…”

This article proposes a new model for concurrent Lean-Kaizen based on the Lean production thinking. According to the concept and application scenarios of value stream mapping and DMAIC (Define, Measure, Analyze, Improve, and Control), we proposed an integrated VSM-DMAIC by adopting their advantages and avoiding their disadvantages. The VSM-DMAIC model is applied to tackle the production problems on production line. Value stream mapping is used to identify the production problems during production processes by waste identification. Then, the production problems are clustered into different production problem sets according to the changed types of production resources while solving production problems. The data envelopment analysis method is used to rank the production problems by inputoutput ratio, and the most important production problem in each set can be the concurrent Lean-Kaizen. DMAIC provides a structured problem-solving method for production problems. Finally, the production problems and production problem sets will be reassessed for the next concurrent Lean-Kaizen. A case study of an air-conditioner assembly line verified the feasibility and efficiency of the proposed VSM-DMAIC model, which can be used to improve the economic benefits and decrease the waste of production line.

PurposeThe objective of this study is to present a binary-valued data envelopment analysis (DEA) theory. The authors’ proposed approach, for the first time, combines binary-valued and integer-valued theories concurrently in the DEA context. To do so, new production possibility sets (PPSs) with some distinguished features are developed.Design/methodology/approachThe authors address integer inputs and outputs in the proposed approach by introducing a new PPS.FindingsTo take into account the binary data, the authors develop axiomatic DEA principles. The binary production principles guarantee any combination of convexity and feasibility. Furthermore, the authors develop a new DEA model to consider integer and real data. A case study is presented to show the usefulness of the developed models. Using the proposed models, the authors obtained benchmarks to solve the sustainable supplier selection problems.Originality/value(1) For the first time, binary-valued and integer-valued theories are presented in an integrated DEA model. (2) To deal with the pure binary data, a new PPS is proposed. (3) To consider real, integer and binary data, a new PPS is introduced. (4) New technologies are developed to propose feasible solutions. (5) The proposed models can project inefficient decision-making units (DMUs) on efficiency frontier given binary, integer and real data. (6) A case study is given for the performance evaluation of sustainable suppliers.
