As China’s largest urban agglomeration with rapid growth of economy and population, the development Central Plains Urban Agglomeration (CPUA) has been severely restricted by environmental problems. Thus, green performance CPUA is worth studying. This study used panel data 29 cities in from 2003 to 2018 based on Slacks-based Measure Global Malmquist–Luenberger index measure total factor producti...

Supply chain performance evaluation problems are complex problems with multiple criteria and multi-layered internal linking activities. Data Envelopment Analysis (DEA) has been used to evaluate the relative performance of organizational units called Decision Making Units (DMUs). However, the conventional DEA models cannot take into account the complex nature of supply chains with internal linki...

With accelerated urbanisation, continued growth in water demand and the external pressure of from South–North Water Transfer Project, agricultural use Jiangsu is facing a critical situation. Therefore, it important to explore spatial temporal variation efficiency order clarify pathway for improving efficiency. Firstly, Super-Slacks-Based Measure (SBM) model was utilized measure Province, China,...

Least Squares Support Vector Machines (LS-SVMs) were proposed by replacing the inequality constraints inherent to L1-SVMs with equality constraints. So far this idea has only been suggested for a least squares (L2) loss. We describe how this can also be done for the sumof-slacks (L1) loss, yielding a new classifier (Least 1-Norm SVMs) which gives similar models in terms of complexity and accura...

This paper develops a new factor-analysis-based (FAB) approach for choosing the optimal direction in directional distance function (DDF) analysis. It has combined merits of factor analysis and slacks-based measure (SBM) incorporates relative ease with which various input-output could be adjusted. development relieves reliance on price information that is difficult to obtain provision public goo...

Conventional data envelopment analysis (DEA) methods assume that input and output variables are continuous. However, in many real managerial cases, some inputs and/or outputs can only take integer values. Simply rounding the performance targets to the nearest integers can lead to misleading solutions and efficiency evaluation. Addressing this kind of integer-valued data, the current paper propo...

Support Vector Machines choose the hypothesis corresponding to the centre of the largest hypersphere that can be inscribed in version space. If version space is elongated or irregularly shaped a potentially superior approach is take into account the whole of version space. We propose to construct the Bayes point which is approximated by the centre of mass. Our implementation of a Bayes Point Ma...

As the aging of China’s population continues to intensify as well deepen, and fiscal support increase, improving efficiency expenditure on undertakings has become key actively responding national strategy sustainable aging. This paper uses a global super-efficiency slacks-based measure model in China from 2011 2020. The results show, firstly, that values are generally increasing. eastern region...
