Spatially-explicit sensitivity and uncertainty analysis in a MCDA-based flood vulnerability model
International Journal of Geographical Information Science, 2019This study presents a methodology for conducting sensitivity and uncertainty analysis of a GIS-based multi-criteria model used to assess flood vulnerability in a case study in Brazil.

The uncertainty tree: Reducing the uncertainty of uncertainty analysis
Review of Scientific Instruments, 2002Uncertainty analysis is an integral aspect of experimental measurements, though accurately assessing the flow of uncertainty in a measurement system—particularly for complicated systems with more than a few variables—can become a challenging, error-prone task, while being less enjoyable than it should be.

Investment Analysis Under Uncertainty
Management Science, 1969Investment projects are described in this paper as a pattern of uncertain cash flows over time; i.e., as a cash flow pattern over an event tree. Whereas the portfolio problem of selecting projects generally requires simultaneous consideration of all available projects, here we seek sufficient conditions for accepting and rejecting individual projects.

Financial Analysis in uncertainty [PDF]
, 2001 It is an unquestionable fact that the social surroundings in which businesses operate have an obvious influence on their financial structures at all times and also on the prospects for their evolution in the future.

The Propagation and Analysis of Uncertainty
1990Introduction Suppose we have constructed a model to predict the consequences of various possible events and decisions. And suppose further we have identified various uncertainties in the inputs. How can we propagate these uncertainties through the model to discover the uncertainty in the predicted consequences?

Interactive uncertainty analysis
Proceedings of the 2012 ACM international conference on Intelligent User Interfaces, 2012Humans have difficulty evaluating the effects of uncertainty on schedules. People often mitigate the effects of uncertainty by adding slack based on experience and non-stochastic analyses such as the critical path method (CPM). This is costly as it leads to longer than necessary schedules, and can be ineffective without a clear understanding of where ...

Sensitivity and Uncertainty Analysis [PDF]
, 2012 LCA data quality issues were investigated by using case studies on products from starch-PVOH biopolymers and petrochemical alternatives. These case studies demonstrated that the parameters and assumptions in the database as well as the characterization and normalization methods need to be addressed in sensitivity analysis in order to draw robust LCA ...

On Chu spaces in uncertainty analysis
International Journal of Intelligent Systems, 2000Summary: A very general algebraic framework, known as Chu spaces, has recently been systematically used in modeling of information flow in distributed systems and in modeling of concurrency in computer science. In this paper, we explore this framework in the context of uncertainty modeling and analysis.

Nasendoscopy: An Analysis of Measurement Uncertainties
The Cleft Palate Craniofacial Journal, 2013Objective The purpose of this study was to analyze the optical characteristics of two different nasendoscopes used to assess velopharyngeal insufficiency and to quantify the measurement uncertainties that will occur in a typical set of clinical data.

Abstract : The Wright-Patterson Air Force Base Advanced Turbine Aerothermal Research Rig (ATARR) is a short-duration, turbine stage testing facility. The ATARR facility is designed for a nominal 2-second run time. This long run time created the requirement for fast-acting shut-off valves to avoid over-heating the eddy brake system and other potential ...
