RISTwo-Level Nonlinear Mixed Discrete-Continuous Optimization-Based Design: An Application to Printed Circuit Board Assemblies
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, a new approach for optimization-based design of nonlinearly mixed discrete-continuous problems has been developed. The approach is based on a two-level decomposition strategy in ...
A Feasibility Robust Optimization Method Using Sensitivity Region Concept
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: We present a robust optimization method that ensures feasibility of an optimized design when there are uncontrollable variations in design parameters. This method is developed based on the notion ...
An Automated Procedure for Local Monotonicity Analysis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A strategy for selecting active constraints in a design optimization program is implemented computationally. The strategy uses local monotonicity information to iterate on the active set. A fully ...
A Case for a Knowledge-Based Active Set Strategy
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A strategy for selecting active constraints in a design optimization program is proposed. The strategy differs from previous ones in that it suggests a combination of local and global knowledge. ...
Multiobjective Collaborative Robust Optimization With Interval Uncertainty and Interdisciplinary Uncertainty Propagation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: We present a new solution approach for multidisciplinary design optimization (MDO) problems that, for the first time in literature, has all of the following characteristics: Each discipline has ...
Multi-Level Design Optimization Using Global Monotonicity Analysis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper describes application of global monotonicity analysis within a mutli-level design optimization framework. We present a general formulation and solution procedure, based on a bottom-level ...
Parameter Sensitivity Analysis in Two-Level Design Optimization
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Parameter sensitivity analysis of a two-level design optimization problem can be decomposed into two levels. In the first-level, the sensitivities of the subproblems are calculated separately. In ...
Product Design Selection With Preference and Attribute Variability for an Implicit Value Function
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An important aspect of engineering product design selection is the inevitable presence of variability in the selection process. There are mainly two types of variability: variability in the ...
Optimality and Constrained Derivatives in Two-Level Design Optimization
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The objective of this paper is twofold. First, an optimality test is presented to show that the optimality conditions for a separable two-level design optimization problem before and after its ...
Non-Gradient Based Parameter Sensitivity Estimation for Single Objective Robust Design Optimization
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: We present a method for estimating the parameter sensitivity of a design alternative for use in single objective robust design optimization. The method is non-gradient based: it is applicable ...
