An augmented Lagrangian coordination method for distributed optimal design in MDO: Part I formulation and algorithms
Quite a number of coordination methods have been proposed for the distributed optimal design of large-scale systems consisting of a number of interacting subsystems. Several coordination methods are known to have numerical convergence difficulties that can be explained theoretically. The methods for which convergence proofs are available have mostly been developed for so called quasi-separable ...
متن کاملAugmented Lagrangian Coordination for Decomposed Design Problems
Designing large-scale systems frequently involves solving a complex mathematical program that requires, for various reasons, decomposition into a number of smaller systems. Practical studies have proved the effectiveness of multilevel hierarchical methods at early stages of design; these methods divide a large program into multiple levels and multiple systems at each level and the result is kno...
متن کاملConsistency Constraint Allocation in Augmented Lagrangian Coordination
Many engineering systems are too complex to design as a single entity. Decomposition-based design optimization methods partition a system design problem into subproblems, and coordinate subproblem solutions toward an optimal system design. Recent work has addressed formal methods for determining an ideal system partition and coordination strategy, but coordination decisions have been limited to...
متن کاملAn augmented Lagrangian method for distributed optimization
We propose a novel distributed method for convex optimization problems with a certain separability structure. The method is based on the augmented Lagrangian framework. We analyze its convergence and provide an application to two network models, as well as to a two-stage stochastic optimization problem. The proposed method compares favorably to two augmented Lagrangian decomposition methods kno...
متن کاملAugmented Lagrangian Techniques for Ellipticstate Constrained Optimal Control
We propose augmented Lagrangian methods to solve state and control constrained optimal control problems. The approachis based on the Lagrangianformulationof nonsmoothconvex optimization in Hilbert spaces developed in 6]. We investigate a linear optimal control problem with a boundary control function as in 1]. Both the equation and the constraints are augmented. The proposed methods are general...
