Solution of complex system design problems using distributed, decomposition-based optimization methods requires determination of appropriate problem partitioning and coordination strategies. Previous optimal partitioning techniques have not addressed the coordination issue explicitly. This article presents a formal approach to simultaneous partitioning and coordination strategy decisions that can provide insights on whether a decomposition-based method will be effective for a given problem. Pareto-optimal solutions are generated to quantify tradeoffs between the sizes of subproblems and coordination problems, as measures of the computational costs resulting from different partitioning-coordination strategies. Promising preliminary results with small test problems are presented. The approach is illustrated on an electric water pump design problem. IntroductionNumerous methods have been developed to solve complex system design problems partitioned into smaller subproblems. This decomposition-based approach can ease several difficulties encountered in system design, such as computational expense and management of complex interactions between system elements. Solving a problem in this way requires system designers to decide how to partition the system into subproblems and how to coordinate solution of subproblems toward a consistent, optimal system design. Partitioning decisions have been studied analytically, while only qualitative guidance exists in the literature

-Electric automobiles are clean, efficient, and powerful but are limited in range. Hybrid designs seek to enhance range through the use of liquid fuel. The energy, force, and power needs of a typical car are reviewed. The relationship to fuel cells as energy sources is discussed. Opportunities in the electrical arena, the mechanical arena, and the fuel cell arena are presented. Two commercial hybrid vehicle examples are presented. The convergence of developments in these areas will dominate hybrid designs as commercial production continues to ramp up.

Abstract-Passive components, and inductors, in particular, contribute greatly to the overall volume of power electronic converters. These components are normally packaged individually with little concern for the overall system. For high-density switching power supplies it is imperative to minimize the volume to as great an extent as possible which implies that the passive component volume usage needs to be improved. This can be accomplished by applying suitable packaging and cooling techniques to these components. In this paper, two inductor structures finding application in a 2.1-kW synchronous automotive converter are described. The air-gap placement, losses, cooling methods, and thermal profiles are analyzed and verified experimentally with an inductor designed for operation at 85 C ambient.Index Terms-Direct heat removal, high power density, high temperature, indirect heat removal, packaging, passive component.
