Whether by design or by practice, systems engineering (SE) processes are used more and more often in Modeling and Simulation (M&S). While the two disciplines are very close, there are some differences that must be taken into account in order to successfully reuse practices from one community to another. In this paper, we introduce the M&S System Development Framework (MS-SDF) that unifies SE and M&S processes. The MS-SDF comprises the SE processes of requirements capture, conceptual modelling, and verification and validation (V&V), and extends them to M&S. We use model theory as a deductive apparatus in order to develop the …

Global Optimization Of Nonconvex Piecewise Linear Regression Splines, Nadia Maria Martinez Cepeda
Industrial, Manufacturing, and Systems Engineering Dissertations - Archive
Global optimization has been applied to a wide variety of science and engineering design problems. Although numerous global optimization techniques have been developed and studied for decades, when used for complex systems such as the design of an aircraft or an automobile, the results are impractical or not completely satisfactory. One of the main drawbacks is the computational CPU time required to solve these problems. The majority of design problems require a significant number of experiments or simulations in order to find a globally best solution; however a single simulation can take between seconds and days to finish. One way …
