The paper leads the application of DEA (data envelopment analysis) into the power engineering bidding estimation practices. The scheme of evaluation carrying out multi-IO indices helps weaken the influence of subjective factor in the power engineering bidding evaluation. The paper builds up the power engineering bid evaluation index system, and in this foundation, it evaluates and analyzes the relative...
The data in traditional DEA model are limited to crisp inputs and outputs, which cannot be precisely obtained in many production processes or social activities. At the same time, the traditional DEA model can not evaluate by using some given reference units. This paper attempts to extend the traditional DEA model and establishes a fuzzy DEA model based on sample data evaluation. To establish this...
The article firstly describes C2R model and C2GS2 model of DEA method; secondly, it determines input and output indexes of Chinese equipment manufacturing and then uses DEA method to make positive measure of technical validity and scale validity about equipment manufacturing's input-output of 31 provinces and municipalities. Based on measure results, the article divides 31 provinces and municipalities...
Based on maximum entropy principle, technological innovation diffusion model of enterprises has been established, which described the process and conditions of technological innovation diffusion. We expanded C2GS2 model based on C2R model of DEA method, and made evaluation on innovation efficiency of enterprises by the software of WINQSB. We show whether the innovation efficiency is best according...
The C2R and C2GS2 model of DEA have been described firstly. Next, in the light of the principle of systemic, scientific and comparability, by integrating the realities of the large and medium Enterprises in China, the evaluation indicator system has been set up. And then, by using the DEA method, the paper has evaluated and analyzed the technical validity and scale validity of technological innovation...
The efficiency evaluation value which is provided by C2R model of data envelopment analysis (DEA) can be used for ranking decision making units (DMUs), however, this ranking procedure does not yield relative rankings for those units with 100% efficiency. Some researchers have proposed a modified efficiency measure for efficient units which can be used for ranking, but this ranking breaks down in some...
