چکیده

Network designing often involves two significant yet contradictive objectives: enhancing the whole network’s transmission efficiency while at the same time lowering the whole network’s designing cost. Deep study of the interplay between major aspects of network planning– network topology, routing algorithm and node’s transmission capability configuration–reveals that good tradeoff canbe achieved between these two objectives. By properly combining network topology, routing algorithm and node capability configuration scheme, the network can achieve desirable transmission efficiency at very low cost. This discovery will undoubtedly provide insight into the next generation data network designing.

The overall efficiency and projection point in network DEA

Data Envelopment Analysis (DEA) is one of the best methods for measuring the efficiency and productivity of Decision Making Units (DMU). Evaluating the efficiency of DMUs which have two or several stages by using the conventional DEA models, is equal to consider them as black box. This method, omits the effect of intermediate measure on efficiency. Therefore, just the first network inputs and t...

Measuring the performances of Medical Diagnostic Laboratories based on interval efficiencies

The classic data envelopment analysis (DEA) models have overlooked the intermediate products, internal interactions and the absence of data certainty; and deal with analyzing the network within the “Black Box” mode. This results in the loss of important information and at times a considerable modification occurs in efficiency results. In this paper, a Three-stage network model is considered wit...

Network ‎D‎ata Envelopment Analysis Models For Measuring Efficiency Of a Four-Stage Supply Chain With Returned Outputs‎

In this paper using DEA technique, four-stage DEA model mooted in order to consider the situation in which returned products exist. Returned products are the inputs of the previous sub-processes that need to be reprocessed due to existence of flaws. Here, a supply chain with four stages as supplier, manufacture, distributor, and retailer with intermediate and return products has been considered...

Measuring the efficiency of a three-stage network using data envelopment analysis approach considering dual boundary

This paper presents a method for performance evaluation, ranking and clustering based on the double-frontier view to analyze the complex networks. The model allows us to open the structure of the “black box” and can help to obtain important information about efficient and inefficient points of the system. In this paper, we consider a three-stage network, in respect to the additional desirable a...
