Download or read book Change Propagation in Large Technical Systems written by Monica Lee Giffin and published by . This book was released on 2007 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: Propagation of engineering changes has gained increasing scrutiny as the complexity and scale of engineered systems has increased. Over the past decade academic interest has risen, yielding some small-scale in-depth studies, as well as a variety of tools aimed at aiding investigation, analysis and prediction of change propagation. This thesis applies many of the methods and seeks to apply and extend prior reasoning through examination of a large data set from industry, including data from more than 41,000 change requests (most technical, but others not) over nearly a decade. Different methods are used to analyze the data from a variety of perspectives, in both the technical and managerial realms, and the results are compared to each other and evaluated in the context of previous findings. Macro-level patterns emerge independent of smaller scale data patterns, and in many cases offer clear implications for technical management approaches for large, complex systems development.

Download or read book Multilayer Network Modeling of Change Propagation for Engineering Change Management written by Michael C. Pasqual and published by . This book was released on 2010 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: Engineering change management is a critical and challenging process within product development. One pervasive source of difficulty for this process is the phenomenon of change propagation, by which a change to one part or element of a design requires additional changes throughout the product. Research efforts to understand and manage change propagation have largely drawn on network analysis. This thesis builds upon past research by introducing a multilayer network model that incorporates three proposed layers, or domains, that contribute to change propagation: namely, the product layer, change layer, and social layer. Each layer contains a distinct network of nodes and intralayer edges, but also connects to the other two layers through inter-layer dependencies. The model facilitates extensive quantitative analysis of change propagation using a repository of single-layer, double-layer, and triple-layer tools and metrics. A case study of a large technical program, which managed over 41,000 change requests in eight years, is employed to demonstrate the practical utility of the model. Most significantly, the case study explores the program's social layer and discovers a real-world correspondence between an engineer's organizational role and the propagation effects of his or her work, as measured by the newly proposed Engineer Change Propagation Index (Engineer-CPI). The case study also reveals that parent-child propagation often spanned more than one, but never more than three, system interfaces, thus confirming the possibility of indirect propagation. Finally, the study finds that propagation always stopped after five, and rarely more than four, generations of descendants. In all, the multilayer network model's holistic approach has significant policy implications for engineering change management in industry.

Download or read book Theory of Technical Systems written by Vladimir Hubka and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 289 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a comprehensive and unifying theory to promote the under standing of technical systems. Such a theory is useful as a foundation for a ratio nal approach to the engineering design process, as a background to engineering education, and other applications. The term "technical system" is used to represent all types of man-made artifacts, including technical products and processes. The technical system is therefore the subject (in the grammatical sense of the word) of the collection of activities which are performed by engineers within the processes of engineering design, including generating, retrieving, processing and transmitting of information about products. It is also the subject of various tasks in the production process, including work preparation and production planning, and in many economic considerations, company-internal and societal. In this way, the Theory of Technical Systems is a contribution to science, as in terpreted in the wider, Germanic sense of a "co-ordinated and codified body of knowledge". It brings together the various viewpoints of engineers, scientists, economists, ergonomists, managers, users, sociologists, etc., and shows where and how they influence the forms of engineering products. It also explains the influ ences that a product exerts on its environment. This Theory of Technical Systems should thus interest design engineers, and en gineers involved in production, management, sales, etc. In an interdisciplinary ap plication of value analysis, the Theory of Technical Systems should provide answers to many questions raised in this field.

Download or read book Transdisciplinary Engineering for Complex Socio technical Systems Real life Applications written by J. Pokojski and published by IOS Press. This book was released on 2020-10-20 with total page 738 pages. Available in PDF, EPUB and Kindle. Book excerpt: Transdisciplinary engineering transcends other inter- and multi-disciplinary ways of working, such as Concurrent Engineering (CE). In particular, transdisciplinary processes are aimed at solving complex, ill-defined problems, or problems for which the solution is not immediately obvious. No one discipline or single person can provide sufficient knowledge to solve such problems, so collaboration is essential. This book presents the proceedings of the 27th ISTE International Conference on Transdisciplinary Engineering, organized by Warsaw University of Technology, Poland, from 1-10 July 2020. ISTE2020 was the first of this conference series to be held virtually, due to the COVID-19 restrictions. Entitled Transdisciplinary Engineering for Complex Socio-technical Systems - Real-life Applications, the book includes 71 peer-reviewed papers presented at the conference by authors from 17 countries. These range from theoretical and conceptual to strongly pragmatic and addressing industrial best practice and, together with invited talks, they have been collated into 9 sections: Transdisciplinary Engineering (7 papers); Transdisciplinary Engineering Education (4 papers); Industry 4.0, Methods and Tools (7 papers); Human-centered Design (8 papers); Methods and Tools for Design and Production (14 papers); Product and Process Development (9 papers); Knowledge and Data Modeling (13 papers); Business Process and Supply Chain Management (7 papers); and Sustainability (2 papers). The book provides an overview of new approaches, methods, tools and their applications, as well as current research and development, and will be of interest to researchers, design practitioners, and educators working in the field.

Download or read book Handbook of Engineering Systems Design written by Anja Maier and published by Springer Nature. This book was released on 2022-07-30 with total page 1040 pages. Available in PDF, EPUB and Kindle. Book excerpt: This handbook charts the new engineering paradigm of engineering systems. It brings together contributions from leading thinkers in the field and discusses the design, management and enabling policy of engineering systems. It contains explorations of core themes including technical and (socio-) organisational complexity, human behaviour and uncertainty. The text includes chapters on the education of future engineers, the way in which interventions can be designed, and presents a look to the future. This book follows the emergence of engineering systems, a new engineering paradigm that will help solve truly global challenges. This global approach is characterised by complex sociotechnical systems that are now co-dependent and highly integrated both functionally and technically as well as by a realisation that we all share the same: climate, natural resources, a highly integrated economical system and a responsibility for global sustainability goals. The new paradigm and approach requires the (re)designing of engineering systems that take into account the shifting dynamics of human behaviour, the influence of global stakeholders, and the need for system integration. The text is a reference point for scholars, engineers and policy leaders who are interested in broadening their current perspective on engineering systems design and in devising interventions to help shape societal futures.

Download or read book A Socio technical Systems Analysis of Change Processes in the Design of Flagship Interplanetary Missions written by Eric Daniel Ward and published by . This book was released on 2016 with total page 107 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the engineering of complex systems, changes to flight hardware or software after initial release can have large impacts on project implementation. Even a comparatively small change on an assembly or subsystem can cascade into a significant amount of rework if it propagates through the system. This can happen when a change affects the interfaces with another subsystem, or if it alters the emergent behavior of the system in a significant way, and is especially critical when subsequent work has already been performed utilizing the initial version. These changes can be driven by new or modified requirements leading to changes in scope, design deficiencies discovered during analysis or test, failures during test, and other such mechanisms. In complex system development, changes are managed through engineering change requests (ECRs) that are communicated to affected elements. While the tracking of changes is critical for the ongoing engineering of a complex project, the ECRs can also reveal trends on the system level that could assist with the management of current and future projects. In an effort to identify systematic trends, this research has analyzed ECRs from two different JPL led space mission projects to classify the change activity and assess change propagation. It employs time analysis of ECR initiation throughout the lifecycle, correlates ECR generators with ECR absorbers, and considers the distribution of ECRs across subsystems. The analyzed projects are the planetary rover mission, Mars Science Laboratory (MSL), and the Earth-orbiting mission, Soil Moisture Active Passive (SMAP). This analysis has shown that there is some consistency across these projects with regard to which subsystems generate or absorb change. The relationship of the ECRSubsystem networks identifies subsystems that are absorbers of change and others that are generators of change. For the flight systems, the strongest absorbers of change were found to be avionics and the mechanical structure for the spacecraft bus, and the strongest generators of change were concentrated in the payloads. When this attribute is recognized, project management can attempt to close ECR networks by looking for ways to leverage absorbers and avoid multipliers. Alternatively, in cases where changes to a subsystem are undesirable, knowing whether it is an absorber can greatly assist with expectations and planning. This analysis identified some significant differences between the two projects as well. While SMAP followed a relatively well behaved blossom profile across the project, MSL had an avalanche of change leading to the drastic action of re-baselining the launch date. While the official reasoning for the slip of the launch date is based in technical difficulties, the avalanche profile implies that a snowballing of change may have had a significant impact as well. Furthermore, the complexity metrics applied show that MSL has a more complex nature than SMAP, with 269 ECRs in 65 Parent-Child clusters, opposed to 166 in 53 for SMAP, respectively. The Process Complexity metric confirms this, quantitatively measuring the complexity of MSL at 492, compared to 367 for SMAP. These tools and metrics confirm the intuition that MSL, as a planetary rover, is a more complex space mission than SMAP, an earth orbiter.

Download or read book Propagation Phenomena in Real World Networks written by Dariusz Król and published by Springer. This book was released on 2015-03-19 with total page 375 pages. Available in PDF, EPUB and Kindle. Book excerpt: “Propagation, which looks at spreading in complex networks, can be seen from many viewpoints; it is undesirable, or desirable, controllable, the mechanisms generating that propagation can be the topic of interest, but in the end all depends on the setting. This book covers leading research on a wide spectrum of propagation phenomenon and the techniques currently used in its modelling, prediction, analysis and control. Fourteen papers range over topics including epidemic models, models for trust inference, coverage strategies for networks, vehicle flow propagation, bio-inspired routing algorithms, P2P botnet attacks and defences, fault propagation in gene-cellular networks, malware propagation for mobile networks, information propagation in crisis situations, financial contagion in interbank networks, and finally how to maximize the spread of influence in social networks. The compendium will be of interest to researchers, those working in social networking, communications and finance and is aimed at providing a base point for further studies on current research. Above all, by bringing together research from such diverse fields, the book seeks to cross-pollinate ideas, and give the reader a glimpse of the breath of current research.”

Download or read book Verification and Validation of Complex Systems Human Factors Issues written by John A. Wise and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 682 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite its increasing importance, the verification and validation of the human-machine interface is perhaps the most overlooked aspect of system development. Although much has been written about the design and developmentprocess, very little organized information is available on how to verifyand validate highly complex and highly coupled dynamic systems. Inability toevaluate such systems adequately may become the limiting factor in our ability to employ systems that our technology and knowledge allow us to design. This volume, based on a NATO Advanced Science Institute held in 1992, is designed to provide guidance for the verification and validation of all highly complex and coupled systems. Air traffic control isused an an example to ensure that the theory is described in terms that will allow its implementation, but the results can be applied to all complex and coupled systems. The volume presents the knowledge and theory ina format that will allow readers from a wide variety of backgrounds to apply it to the systems for which they are responsible. The emphasis is on domains where significant advances have been made in the methods of identifying potential problems and in new testing methods and tools. Also emphasized are techniques to identify the assumptions on which a system is built and to spot their weaknesses.
