Centralized Cost Efficiency DEA Models
Cost efficiency measures the cost of resource by output production. While conventional cost efficiency models set targets separately for each DMU, There are cases where the Central decision making is seeking the above targets, and at the same tries to obtain the target of Min cost efficiency for the total consumption. in this paper we consider that there is a centralized decision maker (DM). In...
متن کاملTechnically Efficient Targets for the Groups by Using the Centralized Scenario and Enhanced Russell Measure
Cooper et al. [Efficiency aggregation with enhanced Russell measures in data envelopment analysis, Socio-Economic Planning Sciences, 41 (2007) 1–21] presented a method for measuring aggregate efficiency, using the enhanced Russell measure. In that paper, they posed questions and opened the way for new opportunities for studying and extending the proposed method and some other related fields. On...
متن کاملCentralized Path Planning for Multi-aircraft in the Presence of Static and Moving Obstacles
This article proposes a new approach for centralized path planning of multiple aircraft in presence of the obstacle-laden environment under low flying rules. The problem considers as a unified nonlinear constraint optimization problem. The minimum time and control investigate as the cost functions and the maximum velocity and power consider as the constraints. The pseudospectral method applies ...
متن کاملEeective Retrieval with Distributed Collections
This paper evaluates the retrieval eeective-ness of distributed information retrieval systems in realistic environments. We nd that when a large number of collections are available, the retrieval eeectiveness is signiicantly worse than that of centralized systems, mainly because typical queries are not adequate for the purpose of choosing the right collections. We propose two techniques to addr...
متن کاملA Mexican case study on a centralised database from world natural history museums
The present contribution is a case study of the possibilities of using data from world scientific collections to understand the distribution and conservation of Mexican birds. Information was gathered on specimens from Mexico housed in 40 scientific collections in Mexico, the United States, Canada, and Europe. This information was compiled in a centralized database and various analyses were dev...
