In this paper we develop on a geometric model of social choice among bundles of interdependent elements (objects). Social choice can be seen as a process of search for optima in a complex multi-dimensional space and objects determine a decomposition of such a space into subspaces. We present a...

Structuring Tchebycheff-Type Inequalities – A Systematical Approach / Systematisierung tschebyscheffartiger Ungleichungen – Ein Überblick

Strotmann, Harald - In: Jahrbücher für Nationalökonomie und Statistik 219 (1999) 3-4, pp. 468-493

Summary Though there is a huge variety of different Tchebycheff-type inequalities in the literature a systematised structuring is missing. The few existing surveys remain rather enumerative. Therefore in this paper a structuring of Tchebycheff-type inequalities is suggested which is based on...

Uncertainties in environmental radiological assessment models and their implications

Hoffman, F.O.; Miller, C.W. - 2008

Environmental radiological assessments rely heavily on the use of mathematical models. The predictions of these models are inherently uncertain because these models are inexact representations of real systems. The major sources of this uncertainty are related to biases in model formulation and...

Methods for developing and validating survivability distributions

Williams, R.L. - 2008

A previous report explored and discussed statistical methods and procedures that may be applied to validate the survivability of a complex system of systems that cannot be tested as an entity. It described a methodology where Monte Carlo simulation was used to develop the system survivability...

Approaches to implementing deterministic models in a probabilistic framework

Talbott, D.V. - 2009

The increasing use of results from probabilistic risk assessments in the decision-making process makes it ever more important to eliminate simplifications in probabilistic models that might lead to conservative results. One area in which conservative simplifications are often made is modeling...

Determining perception-based impacts of noxious facilities on wage rates and property values

Nieves, L.A.; Clark, D.E. - 2008

This document, written for the US Department of Energy, discusses current information and the need for future research on estimating the impacts on wages and property values that could result from people's perceptions of the risks associated with noxious facilities. Psychometric studies indicate...
