Coupling the Worst Scenario Method with Fuzzy Input Data
Chleboun, Jan
Inputs entering a mathematical model are considered uncertain, i.e., they are not given in a crisp form but only within a set of admissible data. The solution to the model is evaluated through a functional (criterion) reflecting a particular feature of the solution, e.g., local temperature, velocity, stress. The higher value, the "worse" solution. The goal of the worst scenario method...
Uncertainties in modeling: where do they come from? What actions can we take?
Chleboun, Jan
Basic types and sources of uncertainty in mathematical modeling are brieefly mentioned. The notions of validation and verification are explained. A few preferrable features of mathematical models are listed. Stochastic and nonstochastic approaches to uncertainty in modeling are presented.
Worst scenario method applied to heat conductivity structures formed by composite materials
Chleboun, Jan
Uncertain conductivity coefficients are considered. They are not given directly bat they stem from an admissible family of composite materials characterized by uncertain concentrations of their constituents. The goal is to maximize a weakly continuous **st functional and to suggest an approximate method suitable for numerical solution of the problem.
Numerical solution of a temperature distribution problem in a body with uncertain heat conductivity coefficients
Chleboun, Jan
Time independent heat flow problems are considered. The heat conductivity coefficients depend on temperature and are not known exactly. The goal is to find the maximum reachable temperature in a fixed test subregion if coefficients are taken from certain compact admissible set. Results of the sensitivity analysis for isotropic as well as anisotropic bodies are given together with results of numerical examples.
