• Efficiency of operational processes with undesirable outputs containing series and parallel processes. Developing a network Slacks-Based DEA model to include components. A Slack-Based data envelopment analysis for measuring efficiency banks. An assessment Chinese commercial banks considering both This paper proposes new slacks-based measure (SBM-NDEA) evaluate the performance production that ...

the index is excellent by the malmquist index as extended to productivity measurement. the index developed here is defined in terms of input cost rather than input quantity distance functions in supply chain. therefore, we propose productivity change is decomposed into overall efficiency and cost technical change. these decompositions provide a clearer situation of the root sources of supply ch...

The overall efficiency and energy consumption problem in hydraulic power pack units with without an additional pre-charging system was analyzed this paper. A theoretical mathematical model developed for calculating losses both pump unit structures. To verify the relationships, a laboratory test stand built, upon which results of were compared tests. Universal diagrams dependence as function pre...

Abstract This chapter introduces the overall research question as well how it will be addressed and answered throughout book.

Abstract Under the changing environment, problems of water cycle and resources in basin become extremely complex, coordination use efficiency fairness is difficult. This paper takes Yellow River Basin as key research area creates a balanced allocation method model that take into account use. The dynamic equilibrium increment brought by new source projects regulation realized, fine-tuning optimi...

Abstract Hydrogen is a promising future sustainable fuel candidate with boundless opportunities. Research into photoelectrochemical (PEC) water splitting based on lead halide perovskite (LHP) has progressed significantly the aim of more efficient solar hydrogen production. Herein, we unite well‐known photo‐absorbing LHP cost‐effective water‐splitting catalysts, and introduce two types monolithi...
