An Analysis of the UK Auto Component Industry: From the perspective of a Tier 2 safety software company

The automotive industry is a large critical sector to UK economy as it accounts for close to a million jobs and is the highest exporter for the country. The industry is characterised by the presence of world’s major OEMs and Tier 1 suppliers along with a wide chain of other suppliers. The relationship between these players has mostly been studied only to the extent of OEMs and Tier 1 suppliers, leaving a gap in establishing the relationship with Tier 2 suppliers with the other two. This industry has been in the news for quite some time for being less competitive due to low growth and high number of players but there are also positive news about various government initiatives to promote low carbon development and to boost up the existing supply chain. This report aims to unravel the nature of relationship between OEM/Tier 1 suppliers and Tier 2 suppliers in the UK auto component sector and also to discover opportunities that might be present for Silver Atena, a new Tier 2 safety critical supplier. In doing so, first the auto component market structure has been studied to ascertain the current opportunities, trends, government initiatives etc. The relationship between OEM/Tier 1 and Tier 2 suppliers has helped in segmenting the clients into three: Tier 1 suppliers, R&D centres and Design Engineering centres. Based on this segmentation, an exhaustive client and competitor analysis has been provided. It is also observed that most current developments are taking place in the fields of electronics/electrical components involving software which makes it a good proposition for Silver Atena. This report has identified four domains for Silver Atena to focus on viz. powertrain, vehicle control, driver assistance and infotainment & telematics. Even though the future seemed bright, when the current market conditions were analysed it revealed that most participants are making very low profits and even losses making it a very unattractive market to be in. However, based on the future prospects in hybrid, electric and fuel cell technologies, the report has made recommendations for Silver and has also highlighted the challenges that Silver Atena needs to overcome in order to make a successful entry into the auto component market by leveraging its existing skills

A multiobjective, multidisciplinary design optimization methodology for the conceptual design of distributed satellite systems

Thesis (Ph. D.)--Massachusetts Institute of Technology, Dept. of Aeronautics and Astronautics, 2002.Includes bibliographical references (p. 427-438).This electronic version was submitted by the student author. The certified thesis is available in the Institute Archives and Special Collections.A multiobjective, multidisciplinary design optimization methodology for mathematically modeling the distributed satellite system (DSS) conceptual design problem as an optimization problem has been developed to advance the state-of-the-art in complex distributed satellite network design. An increasing number of space missions are utilizing DSS architectures in which multiple satellites work in a coordinated fashion to improve system performance, cost, and survivability. The trade space for distributed satellite systems can be enormous - too large to enumerate, analyze, and compare all possible architectures. The seven-step methodology enables an efficient search of the trade space for the best families of architectures, and explores architectures that might not otherwise be considered during the conceptual design phase, the phase of a DSS program in which the majority of lifecycle cost gets locked in. Four classes of multidisciplinary design optimization (MDO) techniques are investigated - Taguchi, heuristic, gradient, and univariate methods. The heuristic simulated annealing (SA) algorithm found the best DSS architectures with the greatest consistency due to its ability to escape local optima within a nonconvex trade space. Accordingly, this SA algorithm forms the core single objective MDO algorithm in the methodology. The DSS conceptual design problem scope is then broadened by expanding from single objective to multiobjective optimization problems, and two variant multiobjective SA algorithms are developed.(cont.) The utility in knowing the global Pareto boundary of a DSS trade space is presented, and several methods are explored for approximating the true global Pareto boundary with only a limited knowledge of the full DSS trade space. Finally, methods for improving the performance of the SA algorithm are tested, and it was found that the 2-DOF variant of the SA algorithm is most effective at both single objective and multiobjective searches of a DSS trade space. The versatility of the methodology is demonstrated through its application to the conceptual design of three separate distributed satellite systems - the civil NASA Origins Terrestrial Planet Finder mission, the military TechSat 21 GMTI space-based radar mission, and the commercial broadband satellite communications mission. In each case, the methodology identifies more cost-effective system architectures than those previously considered for the single objective optimization problem, and a Pareto optimal set of architectures for the multiobjective optimization problem. In this manner, the methodology serves as a powerful, versatile systems engineering tool for the conceptual design of distributed satellite systems.by Cyrus D. Jilla.Ph.D

Application of advanced technology to space automation

Automated operations in space provide the key to optimized mission design and data acquisition at minimum cost for the future. The results of this study strongly accentuate this statement and should provide further incentive for immediate development of specific automtion technology as defined herein. Essential automation technology requirements were identified for future programs. The study was undertaken to address the future role of automation in the space program, the potential benefits to be derived, and the technology efforts that should be directed toward obtaining these benefits

Abstracts on Radio Direction Finding (1899 - 1995)

The files on this record represent the various databases that originally composed the CD-ROM issue of "Abstracts on Radio Direction Finding" database, which is now part of the Dudley Knox Library's Abstracts and Selected Full Text Documents on Radio Direction Finding (1899 - 1995) Collection. (See Calhoun record https://calhoun.nps.edu/handle/10945/57364 for further information on this collection and the bibliography). Due to issues of technological obsolescence preventing current and future audiences from accessing the bibliography, DKL exported and converted into the three files on this record the various databases contained in the CD-ROM. The contents of these files are: 1) RDFA_CompleteBibliography_xls.zip [RDFA_CompleteBibliography.xls: Metadata for the complete bibliography, in Excel 97-2003 Workbook format; RDFA_Glossary.xls: Glossary of terms, in Excel 97-2003 Workbookformat; RDFA_Biographies.xls: Biographies of leading figures, in Excel 97-2003 Workbook format]; 2) RDFA_CompleteBibliography_csv.zip [RDFA_CompleteBibliography.TXT: Metadata for the complete bibliography, in CSV format; RDFA_Glossary.TXT: Glossary of terms, in CSV format; RDFA_Biographies.TXT: Biographies of leading figures, in CSV format]; 3) RDFA_CompleteBibliography.pdf: A human readable display of the bibliographic data, as a means of double-checking any possible deviations due to conversion
