This paper is a survey of recent contributions to and developments in the relationship between efficiency and productivity via the production function. The objective is to provide a brief discussion on data and on the methods of measuring efficiency and productivity. First, we introduce the reader to the measurement of partial and total factor productivity in the context of static and firm - sp...

this paper talks about the measurement of efficiency and productivity of non-life insurance firms in india. this study is focused on twelve private non-life insurance firms and four public sector non-life insurance firms of india in the period 2008-09 to 2012-13. data envelopment analysis (dea) coupled with malmquist productivity index is used in measuring the efficiency as well as productivity...

the efficiency measurement is a subject of great interest. the majority of studies on dea models have been carried out using radial or non-radial approaches regarding the application of dea for the efficiency measurement. this paper, based on the directional distance function, proposes a new generalized hybrid measure of efficiency under generalized returns to scale with the existence of both r...

energy, due to its increasing usage in various broad areas has been maintained as a vital factor in economic growth and development of societies. meanwhile, natural gas is considered as one of the most important energy sources. therefore, the efficiency and the productivity of the gas companies are crucial to be assessed. numerous examples from industrial multistage processes including internal...

The efficiency measurement is a subject of great interest. The majority of studies on DEA models have been carried out using radial or non-radial approaches regarding the application of DEA for the efficiency measurement. This paper, based on the directional distance function, proposes a new generalized hybrid measure of efficiency under generalized returns to scale with the existence of both r...

We investigate that no-knowledge measurement-based feedback control is utilized to obtain the estimation precision of the detection efficiency. For the feedback operators that concern us, noknowledge measurement is the optimal way to estimate the detection efficiency. We show that the higher precision can be achieved for the lower or larger detection efficiency. It is found that no-knowledge fe...
