This book was released on 2008 with total page 143 pages. Available in PDF, EPUB and Kindle. Book excerpt: The growing size, complexity and demands of engineering systems requires paying greater attention to the initial design of the system concept. To improve the process by which concept design is carried out, this thesis develops an Engineering Framework for Concept Development. The Engineering Framework is applicable to a diverse range of concept design problems. It helps guide the otherwise haphazard process of the early stages of design to provide confidence that the chosen concept is superior to a large set of alternatives. Accompanying the Engineering Framework is a collection of tools which aid the designer in analyzing different options. Two tools in particular are demonstrated for their mutually beneficial characteristics: 1) Object-Process Network is used to explore the full space of options, revealing the relationships among design decisions and system performance, and 2) a particle.swarm optimization algorithm is implemented to efficiently search through the design space. The use of such an optimization algorithm becomes especially advantageous when higher fidelity models are included in the analysis because it is able to quickly identify the most favorable families of designs. The complementary approaches of exploring the entire trade space and then efficiently searching for the best groups of designs are shown to provide valuable insights in concept design problems. Two case study examples are presented as applications of the Engineering Framework and design tools. The first is an air-launched sounding rocket propulsion system design. The second is the design of a responsive disaster monitoring system. In each case, the use of the Engineering Framework and concept design tools give the designer increased confidence that quality concept designs have been identified.

Download or read book Multi objective Design Space Exploration of Multiprocessor SoC Architectures written by Cristina Silvano and published by Springer Science & Business Media. This book was released on 2011-08-23 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book serves as a reference for researchers and designers in Embedded Systems who need to explore design alternatives. It provides a design space exploration methodology for the analysis of system characteristics and the selection of the most appropriate architectural solution to satisfy requirements in terms of performance, power consumption, number of required resources, etc. Coverage focuses on the design of complex multimedia applications, where the choice of the optimal design alternative in terms of application/architecture pair is too complex to be pursued through a full search comparison, especially because of the multi-objective nature of the designer’s goal, the simulation time required and the number of parameters of the multi-core architecture to be optimized concurrently.

This book was released on 2018-06-15 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: The current preliminary design tools lack the product performance, quality and cost prediction fidelity required to design Six Sigma products. They are also frequently incompatible with the tools used in detailed design, leading to a great deal of rework and lost or discarded data in the transition from preliminary to detailed design. Thus, enhanced preliminary design tools are needed in order to produce adequate financial returns to the business. To achieve this goal, GEAE has focused on building the preliminary design system around the same geometric 3D solid model that will be used in detailed design. With this approach, the preliminary designer will no longer convert a flowpath sketch into an engine cross section but rather, automatically create 3D solid geometry for structural integrity, life, weight, cost, complexity, producibility, and maintainability assessments. Likewise, both the preliminary design and the detailed design can benefit from the use of the same preliminary part sizing routines. The design analysis tools will also be integrated with the 3D solid model to eliminate manual transfer of data between programs. GEAE has aggressively pursued the computerized control of engineering knowledge for many years. Through its study and validation of 3D CAD programs and processes, GEAE concluded that total system control was not feasible at that time. Prior CAD tools focused exclusively on detail part geometry and Knowledge Based Engineering systems concentrated on rules input and data output. A system was needed to bridge the gap between the two to capture the total system. With the introduction of WAVE Engineering from UGS, the possibilities of an engineering system control device began to formulate. GEAE decided to investigate the new WAVE functionality to accomplish this task. NASA joined GEAE in funding this validation project through Task Order No. 1. With the validation project complete, the second phase under Task Order No. 2 was established to develo

Download or read book A Framework for Automation of System level Design Space Exploration written by Manan Kathuria and published by . This book was released on 2012 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: Design Space Exploration is the task of identifying optimal implementation architectures for an application. On the front-end, it involves multi-objective optimization through a large space of options, and lends itself to a multitude of algorithmic approaches. On the back-end, it relies extensively on common capabilities such as model refinement, simulation and assessment of parameters like performance and cost. These characteristics present an opportunity to create an infrastructure that enables multiple approaches to be deployed using generic back-end services. In this work, we describe such a framework, developed using the System-on-Chip Environment, and we demonstrate the benefits and feasibility of deploying a variety of design space exploration approaches built on top of this basic infrastructure.
