An Interval Based Approach To Model Input Uncertainty In Discrete-Event Simulation, Ola Batarseh
An Interval Based Approach To Model Input Uncertainty In Discrete-Event Simulation, Ola Batarseh
Electronic Theses and Dissertations
The objective of this research is to increase the robustness of discrete-event simulation (DES) when input uncertainties associated models and parameters are present. Input uncertainties in simulation have different sources, including lack of data, conflicting information and beliefs, lack of introspection, measurement errors, and lack of information about dependency. A reliable solution is obtained from a simulation mechanism that accounts for these uncertainty components in simulation. An interval-based simulation (IBS) mechanism based on imprecise probabilities is proposed, where the statistical distribution parameters in simulation are intervals instead of precise real numbers. This approach incorporates variability and uncertainty in systems. In …
