Firms collaborate to develop and deliver new products. These collaborations vary in terms of the similarity of the competencies that partnering firms bring to the alliance. In same-function alliances, partnering firms have similar competencies, whereas in cross-function alliances, partners have...

then uses an event tree to develop a set of compromise paths. Probability models are developed for each of the compromise … paths that user parameters based on expert judgment or historical data on security violations. The resulting probability …. Application of the methodology is demonstrated using a national security example. A set of compromise paths and probability models …

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...

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...

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...

Concentrations of environmental pollutants tend to follow positively skewed frequency distributions. Two such density functions are the gamma and lognormal. Minimum variance unbiased estimators of the expected value for both densities are available. The small sample statistical properties of...

probability of individual component failure is sometimes interpreted as the percentage of components likely to fail, this … multiplying by the probability of individual component failure. However, more complicated cost models require a break down of how … many components are likely to fail. This break down enables the calculation of costs associated with various probability of …
