Environmental efficiency measurement based on DEA Malmquist model: a case study of Henan Province [PDF]
E3S Web of Conferences, 2021 Based on the panel data of different cities in Henan Province from 2010 to 2016, DEA model with variable scale compensation and Malmquist index model are used to measure environmental efficiency from static and dynamic perspectives. The results show that

Axiomatic and Dynamic Results for Power Indexes under Symmetry
Axioms, 2021 Symmetry exists in a multitude of phenomena in varying forms. The main aim of this article is to analyze the plausibility of the equal allocation non-separable costs, the efficient Banzhaf–Owen index and the efficient Banzhaf–Coleman index from the ...

Evaluating the effect of alternative carbon allocation schemes in a land surface model (CLM4.5) on carbon fluxes, pools, and turnover in temperate forests [PDF]
Geoscientific Model Development, 2017 How carbon (C) is allocated to different plant tissues (leaves, stem, and roots) determines how long C remains in plant biomass and thus remains a central challenge for understanding the global C cycle. We used a diverse set of observations (AmeriFlux

SYSTEM DYNAMICS APPROACH FOR EVALUATING EXISTING AND FUTURE WATER ALLOCATION PLANNING AMONG CONFLICTING USERS [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2020 Water shortages are a chronic and severe problem in South Africa. Allocation of this limited water resources, environmental quality, and policies for sustainable water use are issues of increasing concern that require accurate and timely information to ...

Tracking the Dynamics and Allocating Tests for COVID-19 in Real-Time: An Acceleration Index with an Application to French Age Groups and Départements [PDF]
SSRN Electronic Journal, 2020 Abstract An acceleration index is proposed as a novel indicator to track the dynamics of the COVID-19 in real-time. Using French data on cases and tests for the period following the first lock-down - from May 13, 2020, onwards - our acceleration index shows that the ongoing pandemic resurgence can be dated to begin around July 7.

On the dynamic allocation of assets subject to failure
European Journal of Operational Research, 2020 Motivated by situations arising in surveillance, search and monitoring, in this paper we study dynamic allocation of assets which tend to fail, requiring replenishment before once again being available for operation on one of the available tasks. We cast
