The fourth party logistics which acts as a new role will increasingly play more and more important functions. In this paper, for a given deformation problems of 4PL providers’ evaluation, We builds up a fourth party logistics evaluating indicator system based on four factors, which are quality, technical abilities, collaboration and price. Besides, we studies the analysis methods of grey correl...

TAMBARAM KAILASAM, GAYATHRI. Efficient Skycube Computation using Bitmaps derived from Indexes. (Under the direction of Dr. Jaewoo Kang.) Skyline queries have been increasingly used in multi-criteria decision making and data mining applications. They retrieve a set of interesting points from a potentially large set of data points. A point is said to be interesting if it is as good or better in a...

Classic data envelopment analysis (DEA) models determine the efficiency of productive units, called decision making units (DMUs). DEA uses as its methodology the equiproportional reduction of inputs or increase of outputs and the finding of a single target for each DMU. This target does not incorporate the preference of the decision maker. Later works propose obtaining alternative targets based...

We wish to propose a database architecture combining a general view of bioinformatics data as a graph of nodes (data objects) and edges (data relationships), with the efficiency and robustness of data management and query provided by indexing and generic programming techniques. We refer to this architecture as “inverting the database” because it replaces tabular schema—the primary interface of ...

In the first part of this work, combined heat and power (CHP) criteria pertaining to energy, exergy, environmental (pollutant emission) and economic aspects, have been investigated and compared. Although the constraints in legislation usually refer to energy efficiency, primary energy savings and greenhouse gas savings, other criteria should also be taken into account in order to obtain a bette...

Planning for electricity generation systems is a very important task and should take environmental and economic factors into account. This paper reviews the existing metrics and methods in evaluating energy sustainability, and we propose a sustainability assessment index system. The input indexes include generation capacity, generation cost, and land use. The output indexes include desirable an...
