Reducing energy consumption has become a pressing issue in cluster computing systems not only for minimizing electricity cost, but also for improving system reliability. Therefore, it is highly desirable to design energy-efficient scheduling algorithms for applications running on clusters. In this paper, we address the problem of non-preemptively scheduling mixed tasks on power-aware clusters. ...

As a significant tourist destination, development tourism industry in great significance for promoting local economic, social, environmental sustainability. study spatiotemporal evolution ecological efficiency beneficial optimizing investment resource...

Abstract In the framework of data envelopment analysis (DEA), Tone (Eur J Oper Res 130(3):498–509, 2001) introduced slacks-based measure (SBM) efficiency, which is a nonradial model that incorporates all slacks evaluated decision-making units (DMUs) into their efficiency scores, unlike classical radial models. Next, 143(1):32–41, 2002) developed SBM super-efficiency in order to differentiate an...

  The present study is an attempt towards remodeling cost, revenue and profit relationship within the network process. The previous models of Data Envelopment Analysis (DEA) have been too general in their scope and focused on the input and the output within a black box system, therefore they have not been able to measure various phases simultaneously within a network system. By using these mod...

In the prior literature onmeasuring the efficiency of two-stage processes, there are both radial and non-radial methods of efficiency measurement. In some cases, non-radial methods which allow all inputs, intermediate measures and outputs to change non-proportionally are more appropriate than radial methods, but they do not ensure stage efficiency or allow for the efficiency decomposition of tw...

This paper employs a three-stage approach to estimate low carbon economy efficiency in the largest twenty CO₂ emitting countries from 2000 to 2012. The approach includes the following three stages: (1) use of a data envelopment analysis (DEA) model with undesirable output to estimate the low carbon economy efficiency and calculate the input and output slacks; (2) use of a stochastic frontier ap...

Despite the many advantages of interior-point algorithms over active-set methods for linear programming, one of their practical limitations is the remaining challenge to efficiently solve several related problems by an effective warmstarting strategy. Similar to earlier approaches that modify the initial problem by shifting the boundary of its feasible region, the contribution of this paper is ...

In this paper, we use the multi-stage network slacks-based measure model under uncertainty to evaluate performance of Taiwanese financial holding companies (FHCs) from 2007 2012. We conceptualize value creation process be a two-stage framework, as profitability and marketability stages with serial-linkage relationship, in order solicit more information FHCs. Under stage can further divided into...
