Abstract :
The convexity of meta-frontier is a debated topic in data envelopment analysis (DEA). This paper claims that meta-frontier is a non-convex hull, but the production activities between the non-convex meta-frontier and the convex traditional production frontier may be feasible. Therefore, technology compatibility is defined to explain this feasibility, and a modified DEA model is constructed to evaluate the efficiency of decision-making units with technology heterogeneity and technology compatibility. Sequentially, two new meta-frontier DEA frameworks are constructed to evaluate and decompose efficiency, thereby revealing the impact of technology heterogeneity and technology compatibility on efficiency. In addition, a series of discussions are presented to analyze these two new frameworks.

Abstract :
Scientific investment forecasting can effectively avoid the blind investments of environmental management. Among existing studies in developing investment forecasting models, the extended belief rule-based system (EBRBS) showed its potential to accurately predict environment investments but also exposed two challenges to be further addressed: (1) how to select antecedent attributes from various environmental indicators for the EBRBS; (2) how to optimize basic parameters of the EBRBS based on the selected antecedent attributes. Since these two challenges are connected, a bi-level joint optimization model is proposed to improve the EBRBS for better environmental investment forecasting, in which the selection of antecedent attributes is described as an upper-level optimization model using Akaike information criterion (AIC) and the optimization of basic parameters is as a lower-level optimization model using mean absolute error (MAE). Moreover, a corresponding bilevel joint optimization algorithm is proposed to solve the bi-level joint optimization model, where ensemble feature selection and swarm intelligence optimization are regarded as the engine of upperlevel and lower-level optimizations, respectively. The real environmental data collected from 2005 to 2020 of 30 Chinese provinces are studied to verify the effectiveness of the proposed approach. Experimental results show that the EBRBS with bi-level joint optimization not only can effectively predict environmental investments, but also is able to have desired accuracy better than previous investment forecasting models.

Abstract :
Logistics provider selection is a multi-criteria decision-making problem faced by e-commerce companies. Considering the complexity of the problem and the uncertainty of the decision information, an integrated approach of GTOPSIS is proposed for evaluating and selecting the most suitable logistics provider. The GTOPSIS approach integrates the three-parameter interval grey number (T-PIGN) into the technique for order preference by similarity to ideal solution (TOPSIS). It allows decision-makers to use T-PIGN to represent the performance of the alternatives which can retain and utilise the original uncertain assessment information of alternatives to the greatest extent. Besides, the PERT distribution is adopted to weight the three parameters of T-PIGN. A real-life case study is presented to demonstrate the practicality and effectiveness of the GTOPSIS approach.

Abstract :
The allocation mechanism of carbon abatement quotas is a vital issue in the carbon emission abatement (CEA) for the environment and sustainability. The conventional CEA allocation focuses on the imposition of carbon quotas but hardly considers the techniques or mechanisms of abatement. The neglect of the abatement mechanisms may cause inapplicability and unavailability in the practical implementation of CEA allocation. To fill this gap, this paper firstly recognizes and distinguishes two kinds of non-separable relationships among energy inputs, capital investments, and carbon emission. Thereafter, three carbon abatement mechanisms are formed and defined. Then, three scenarios of carbon abatement, named managerial, technical, and hybrid scenarios, are constructed based on the carbon abatement mechanism, in which the carbon emission is, respectively, abated by reducing energy inputs and increasing capital investment and the hybrid measure of energy decrease and capital investment increase. With the developed carbon abatement mechanisms, a carbon abatement allocation application of the regional highway transportation systems in China is illustrated. It finds that the carbon abatement allocations based on the proposed carbon abatement mechanisms help to narrow the regional highway transportation system gaps in China, and the outputs perform the best under the managerial scenario. The Eastern bears more carbon abatement burdens than the Central and West under both managerial and technical scenarios. The Central and West can improve their outputs and bear more carbon abatement burden under hybrid scenarios. The central authority can choose the CEA technique and allocation scheme in line with its preference and observation.

Abstract :
针对由交叉效率评价策略和交叉效率集结方法的多样性而造成评价结果不一致的问题,提出利用证据推理方法和前景理论,综合各个交叉效率评价策略的评价结果,实现对决策单元的统一评价.首先,分别将选用的交叉效率评价策略以及各个评价策略中的他评效率设置成一级指标和二级指标,依据算数平均和前景理论分别确定一、二级指标的权重;其次,依据他评效率确定二级指标置信度,利用证据推理方法将各个交叉效率评价策略的他评效率综合转换成决策单元被评价为有效的置信度.决策者可通过比较决策单元被识别为有效的置信度的大小来判断决策单元交叉效率的大小,进而实现对决策单元的排序;最后,通过案例验证和说明本文提出方法的有效性和实用性.

Abstract :
资源优化配置对于当前我国经济的可持续和高质量发展具有重要意义.针对管理实践中存在的一类产出具有包容关系的结构异质系统的资源配置问题,从中央决策者的视角出发,在异质性效率评价模型的基础上,以最大化所有单元的总产出增加量为主要目标,提出了一种考虑中央主导权的资源优化配置的方法,并证明了各决策单元资源分配后的效率值大于等于分配前的效率值.最后,将其应用于分析我国18个省份的公共交通系统的资源优化配置中,所得结果表明该方法能够较好地实现被分析省份的资源优化配置,同时还能够提升非有效区域的资源配置效率,具有较强的有效性和实用性.
