INTEGRATION OF MODEL-BASED SYSTEMS ENGINEERING AND VIRTUAL ENGINEERING TOOLS FOR DETAILED DESIGN by AKSHA Y KANDE A THESIS Presented to the Faculty of the Graduate School of the MISSOURI UNIVERSITY OF SCIENCE AND TECHNOLOGY In Partial Fulfillment of the Requirements for the Degree MASTER OF SCIENCE IN SYSTEMS ENGINEERING 2011 Approved by Steve Corns, Advisor Cihan Dagli Scott Grasman © 2011 Akshay Kande All Rights Reserved 111 ABSTRACT Design and development of a system can be viewed as a process of transferring and transforming data using a set of tools that form the system's development environment. Conversion of the systems engineering data into useful information is one of the prime objectives of the tools used in the process. With complex systems, the objective is further augmented with a need to represent the information in an accessible and comprehensible manner. The importance of representation is easily understood in light of the fact that the stakeholder's ability to make prompt and appropriate decisions is directly related to his understanding of the available information. Systems Modeling Language (SysML), a graphical modeling language developed by Object Management Group is one such tool used to capture and convey information about a system under development. This work proposes a methodology for integrating the models developed using SysML with virtual engineering software to create an executable, interactive, and user-centered platform for engineering systems. The framework provides an opportunity to combine the benefits offered by both model-based systems engineering and virtual engineering for detail design. This research demonstrates how this framework can be implemented using a biotech fermentor to illustrate the coupling of information between SysML and virtual engineering. lV ACKNOWLEDGMENTS I would like to thank my advisor, Dr. Steve Corns, for his valuable leadership and advice during my graduate studies. I have sincerely enjoyed working on his research projects. I would also like to thank Dr. Cihan Dagli and Dr. Scott Grasman for their valuable input and participation in my committee. I would like to thank my parents, Shekhar and Shilpa Kande, for their love and commitment to make me what I am today. I would also like to thank my grandmother, Vijaya Kande, for her blessings and support. I would like to thank my roommates, Juned Kazi, Ravi Bhatt, Balaji, and Vinayak Bhagwat, for their unconditional support and encouragement throughout my graduate studies. I would also like to thank a very close friend of mine, Shashank Babele, whose willingness to help me when I needed it the most was truly commendable. v TABLE OF CONTENTS Page ABSTRACT ... ................................................................................... .... .... ....................... .. iii ACKNOWLEDGMENTS .. ... ............................................... ................... .. .. ..... ... ... ........... iv LIST OF ILLUSTRATIONS .......................................... .. ................................................ vii LIST OF TABLES ............................................. ... .............................. ............ ................. viii SECTION 1.
