Data envelopment analysis (DEA) is effective to evaluate energy efficiency, but few studies use this technique considering carbon emissions. This paper measures Chinese industrial sector's energy efficiency considering carbon emissions based on the slack-based measure (SBM) model in 1997-2008. The results show that Chinese industrial energy efficiency is relatively low, the average scores (SBM-based)...
Low efficiency and waste are the main problems in the process of coal resources extraction in China. Taking the utilization and recovery rate into account, the article has analyzed the factors influencing the utilization and recovery rate and given some suggestions to improve it by setting up a dynamic optimal model. The analysis result indicates that: (i)the policy based on reserves to impose the...
In view of the supply chain risk evaluation has become the hot-issue and nodus about the supply chain risk management, and it is difficult to embody the requirements about balanced and incentive by the constant weight synthesize in evaluation, then set up a supply chain risk evaluation model based on variable-weights extenics matter-element, by combining the extenics theory with the variable-weights...
The past optimized model of SC network structure always choose not the risk, but rather the cost or customer satisfaction merely as the decision goal, which is not correspondent with practical decision. In order to supply scientific optimized model for decision makers preferring different risks, we introduced CVaR (conditional value-at-risk), a kind of recently developed instrument for measuring financial...
