The efficiency and eco-efficiency of manufacturing

The efficiency and eco-efficiency of manufacturing

In this paper, we review the efficiency of both manufacturing processes and systems over recent decades and compare nano-materials technologies in this context. To a first approximation, nano-materials processes appear to be about as efficient as semi-conductor processes. That is, their second law efficiencies are of the order 10, while conventional processes are of order 10. However, many of t...

assessment of the efficiency of s.p.g.c refineries using network dea

data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...

Technical Efficiency and Eco-Efficiency in the Manufacturing Industry: A Non-Parametric Frontier Approach

Poor environmental performance of the manufacturing activities is said to be attributed to the pollutants produced and emitted during the manufacturing process. These pollutants are regarded as undesirable output and cannot be ignored when measuring the efficiency of manufacturing activities. By applying Data Envelopment Analysis (DEA) and Directional Distance Function (DDF) approaches, this st...
