Researchers in the area of electoral systems have recently turned their attention to network flow techniques with the aim to resolve certain practically relevant problems arising in this area. The aim of the present paper is review some of this work, showing the applicability of these techniques even to problems of a very different nature. Major emphasis will be placed on “biproportional apport...

BARD is the first (and at time of writing, only) open source software package for general redistricting and redistricting analysis. BARD provides methods to create, display, compare, edit, automatically refine, evaluate, and profile political districting plans. BARD aims to provide a framework for scientific analysis of redistricting plans and to facilitate wider public participation in the cre...

A measure of shape compactness is a numerical quantity representing the degree to which a shape is compact. Ways to provide an accurate measure have been given great attention due to its application in a broad range of GIS problems, such as detecting clustering patterns from remote sensing images, understanding urban sprawl, and redrawing electoral districts to avoid gerrymandering. In this pap...

Gerrymandering is returning to the Supreme Court. For the first time in three decades, a federal court invalidated redistricting legislation on the grounds that it constituted a partisan gerrymander in violation of the Fourteenth Amendment. That court relied, in part, on a new tool—the efficiency gap—which some have touted as the means to “end gerrymandering once and for all.” We evaluate this ...

the sensitivity analysis for multi-attribute decision making (madm) problems is important for two reasons: first, the decision matrix as the source of the results of a decision problem is inaccurate because it sorts the alternatives in each criterion inaccurately. second, the decision maker may change his opinions in a time period because of changes in the importance of the criteria and in the ...

this paper develops a single-vendor single-retailer supply chain for multi-product. the proposed model is based on vendor managed inventory (vmi) approach and vendor uses the retailer's data for better decision making. number of orders and available capital are the constraints of the model. in this system, shortages are backordered; therefore, the vendor’s warehouse capacity is another limitati...

agent technology is an emerging and promising research area in software technology, which increasingly contributes to the development of value-added information systems for large healthcare organizations due to its capability to automatically modify themselves in response to changes in their operating environment. multi agent system (mas) approach is the construction of a complex system as a se...
