  • Comprehensive Evaluation of Diesel Engine Quality Based on Multivariate
           and Multi-State Data Using Grey Relational Analysis

    • Abstract: Comprehensive Evaluation of Diesel Engine Quality Based on Multivariate and Multi-State Data Using Grey Relational Analysis
      Pages 1-8
      Author Shenghan ZhouXiaoduo QiaoWenbing ChangXuefeng L
      This paper aims to make a comprehensive evaluation of diesel engine quality based on the trial run data with the characteristics of multivariate and multi-state. Different from the traditional qualitative evaluation, this research will use the trial run data of diesel engine to carry on the quantitative evaluation. First, the trial run data are divided into different states according to the speed of the diesel engine, and then the evaluation of each state is carried out. Finally, the evaluation results of each state are combined to get a comprehensive evaluation. Gray relational analysis is mainly used in this process. In order to get more scientific results, the precedence chart and variation coefficient are respectively used to determine the subjective weight and the objective weight. The validity of the method is proved by an evaluation example.

  • Study on the Efficiency Characteristics of the Economic Development in
           Fujian Province Based on DEA and Malmquist Index

    • Abstract: Study on the Efficiency Characteristics of the Economic Development in Fujian Province Based on DEA and Malmquist Index
      Pages 9-14
      Author Lei HongHuang Xueya
      In this paper, the efficiency characteristics of the economic development of nine cities in Fujian Province are chosen as the research object, collecting 2001-2014 of nine cities in Fujian province input-output data, using data envelopment analysis (DEA) combined with Malmquist productivity index, and the technical efficiency, pure technical efficiency and scale efficiency and total factor productivity are calculated. According to the calculation results, the efficiency characteristics of economic development in different areas are analyzed, and the nine cities are divided into three types according to the efficiency characteristics, and the corresponding policy suggestions are proposed.
