In order to achieve its 2030 carbon emission peak target, China needs adjust and allocate energy consumption initial allowances for each province in a phased planned manner. Thus, this study applied an improved dynamic undesirable zero-sum-gains slacks-based-measure (ZSG-SBM) model evaluate provincial CO2 reduction scenarios allocation 2015–2019 calculate the optimal values of 2030. The results...

Power-aware scheduling reduces CPU energy consumption in hard real-time systems through dynamic voltage scaling(DVS). The basic idea of power-aware scheduling is to find slacks available to tasks and reduce CPU‟s frequency or lower its voltage using the found slacks. In this paper, we introduce temporal workload of a system which specifies how much busy its CPU is to complete the tasks at curre...

In this research we employ data envelopment analysis (DEA) to measure the Malmquist productivity of semiconductor packaging and testing firms in Taiwan from 2000 to 2003. Malmquist productivity has three components: the measurement of technical change, the measurement of the frontier forward shift, and the measurement of the frontier backward shift of a company over two consecutive periods. Thi...

For years, China has adopted environmental regulations in developing ports to improve their sustainability. Based on the data of Chinese from 2009 2018, this paper presents a envelopment analysis model with subdividing input-output indicator weights and develops it further two stages weight preference slacks-based measure, respectively. After assessing sustainable development capability (SDC) s...

Abstract Efficiencies of Agricultural Credit Associations the US Farm System are measured quarterly from 2005 through 2020. A slacks-based measure based on directional distance function is used with non-performing loans included as an undesirable output. This permitted efficiency scores to be by type defined input or Generally, most were highly efficient, but there was deterioration in mean ove...

Many countries are attempting to reduce energy consumption and CO2 emissions while increasing the productivity and efficiency of their industries. An undesirable-output-oriented data envelopment analysis (DEA) model with slacks-based measure (SBM) was used to evaluate the changes in the environmental efficiency of the transportation sector in 30 Chinese provinces (municipalities and autonomous ...
