AND MANAGEMENT IN MODELING AND COMPUTATION H.T. Banks Center for Research in Scienti c Computation Box 8205 North Carolina State University Raleigh, NC 27695-8205 Fax: 919 515-1636 email: [email protected] ABSTRACT We discuss questions related to uncertainty in scienti c computations for mathematical models. A computationally tractable probabilistic framework to treat uncertainty in the estimation of parameters or inverse problems is given. The theory is illustrated by a simple computational example for the estimation of constant parameters in di erential equations by treating the parameters as random variables.

Optimal energy management of microgrid in day-ahead and intra-day markets using a copula-based uncertainty modeling method
Recently, economic and environmental problems have created a strong attitude toward utilizing renewable energy sources (RESs). Nevertheless, uncertainty of wind and solar power leads to a more complicated energy management (EM) of RESs in microgrids. This paper models and solves the EM problem of microgrid from the generation point of view. To do this, mathematical formulation of a grid- connec...

Background: One of the most fundamental objectives of the macroeconomic policies is to realize the relationship between economic growth and inflation. According to some monetary policy advisors, inflation reflects erosion in consumer’s purchasing power. Inflation as an important economic variable, affect the economic growth and its impact on economic growth has been proposed in various theories...
متن کاملA New Uncertain Modeling of Production Project Time and Cost Based on Atanassov Fuzzy Sets
Uncertainty plays a major role in any project evaluation and management process. One of the trickiest parts of any production project work is its cost and time forecasting. Since in the initial phases of production projects uncertainty is at its highest level, a reliable method of project scheduling and cash flow generation is vital to help the managers reach successful implementation of the ...

متن کاملNumerical modeling of economic uncertainty
Representation and modeling of economic uncertainty is addressed by different modeling methods, namely stochastic variables and probabilities, interval analysis, and fuzzy numbers, in particular triple estimates. Fo-cusing on discounted cash flow analysis numerical results are presented, comparisons are made between alter-native modeling methods, and characteristics of the methods are discussed.
