This book was released on 2002-06-01 with total page 219 pages. Available in PDF, EPUB and Kindle. Book excerpt: Manufacturing has evolved to become a critical element of the competitive skill set of defense aerospace firms. Given the changes in the acquisition environment and culture; traditional "thrown over the wall" means of developing and manufacturing products are insufficient. Instead, the development and manufacture of air and spacecraft require much more interaction between the various functions. Also, manufacturing systems are complex systems that need to be carefully designed in a holistic manner and there are shortcomings with available tools and methods to assist in the design of these systems. This thesis proposes and validates a framework to guide the manufacturing system design process. The exploration and validation activities used 14 case studies from major aerostructures, electronics, launch vehicles and spacecraft. Actual manufacturing system design processes were observed real-time or captured retrospectively. An evaluation tool was used to compare the actual manufacturing system design processes with the process proposed by the framework. This degree of congruence with the framework was then compared to a metric of actual/planned performance of the manufacturing system. The results of the framework congruence versus the actual/planned performance metric showed that the case studies that were able to meet their planned performance also had manufacturing system design processes that resembled the process proposed in the framework. But the results also illustrated the different traits between the cases that were able to meet their planned performance and those that were not. Looking at the commonalities between the cases in the groups led to the discovery of the determinants of superior performance: breadth of functional interaction through the design process, use of a manufacturing strategy, the status of the manufacturing function, customer involvement, co-location and an enterprise perspective.

Download or read book Using Data Science and Model Based Systems Engineering to Design and Operate Production Systems written by Ravitej Reddy Kanapuram and published by . This book was released on 2019 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the last several decades, products and the production systems within the aerospace industry have grown increasingly complex -- a natural result of the continuous inclusion of technological advancements to expand the set of features of the systems. Furthermore, design of the production system has historically taken a backseat to the design of the airplane. Modifications to the production systems have thus had to be made after implementation, causing significant delays and additional expenditures. In an effort to halt this trend, prevent some of the inefficiencies from past programs from repeating, and ensure the economic viability of its products, Boeing is exploring how to take a holistic approach and effectively integrate production system design earlier in the program timeline. The primary goal of this research is to investigate how data science and model-based systems engineering (MBSE) can be used to better design and operate production systems. Namely, this work explores how these two methodologies can be used to construct a digital representation of the production system (i.e. "digital twin"), which can in turn be utilized to run stochastic simulations to more accurately characterize how a given production system configuration will perform when the constituent elements themselves behave as random variables. This project is specifically focused on modeling and evaluating a representative portion of the production system, fuselage lamination, which is the process by which layers of carbon-fiber-reinforced-polymer (CFRP) are built-up on mandrels to form the various composite sections of the airplane fuselage prior to being cured in autoclaves. Namely, three different production line configurations responsible for fuselage lamination were compared. It was found that for this particular process, the most effective configuration was not that which would have been chosen based on industry principles. A second objective of this study is to abstract the learnings from this specific implementation to the broader data science and MBSE architecture required to more intelligently design and operate production systems. It is my hope that this work will help demystify the significance of a "digital twin" by providing a concrete example of its use, and garner support for the methodology within organizations by providing clarity on its development requirements, shedding light on the business case for implementation, and offering guidance on how models can be built and used as major levers in developing the premier production system within the industry. Specifically, it hopefully serves as a demonstration of how a detailed, digital representation of the production system can address the issues arising from complexity and enable further system capabilities throughout the lifecycle of the system by offering additional means to effectively build and test concepts in silico.

Download or read book Design for Affordability in Defense and Aerospace Systems Using Tradespace based Methods written by Marcus Shihong Wu and published by . This book was released on 2014 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: Program failures have plagued the defense and aerospace industry for decades, as unanticipated cost and schedule overruns have rendered the development of systems ineffective in terms of time and cost considerations. This raises the need to holistically include performance, cost and schedule considerations during the early-phase design of systems to perform valuable tradeoffs that derive more feasible and affordable solutions. This paradigm is the design for affordability. This design for affordability conundrum is targeted at defense and aerospace systems, which have complex mission requirements and stakeholder involvement that are susceptible to changes and perturbations over time. Without a systematic framework, the design for affordability process can potentially become cognitively challenging to system architects and lead to unsatisfactory results. To resolve affordability, it can first be defined as the property of becoming or remaining feasible relative to resource needs and resource constraints over time. Affordability can then be treated as an ility that drives the design of more affordable yet technically sound architectures. Tradespace-based methods are introduced to drive affordability and incorporate these holistic considerations into the design process. They facilitate the systematic and disciplined search for affordable solutions to the system, program and portfolio of interest. Multi-Attribute Tradespace Exploration (MATE), Epoch-Era Analysis (EEA) and the Multi-Attribute Expense (MAE) function were modified for affordability analysis. Their feasibility was demonstrated through application to two design case studies. Results from both case studies demonstrated the dynamic tradeoffs among performance, cost and schedule parameters. Tradespace-based methods can thus be applied to the progressive design of systems, programs and portfolios using either a bottom-up or top-down approach to deliver affordable solutions in these cases. Affordability is not only an engineering problem; it is also a policy and management problem. Therefore, affordability can be approached through perspectives beyond engineering design. New policies and refined management practices can be used alongside tradespace-based methods for affordability analysis to ensure the continued delivery of affordable systems for the future.
Download or read book Integrated Product Process and Enterprise Design written by Ben Wang and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 505 pages. Available in PDF, EPUB and Kindle. Book excerpt: The need exists in the private sector and government manufacturing sites to reduce product development time, production lead times, inventory, and non-value added activities. At the same time, there is increased pressure to improve manufacturing process yields, produc tion efficiency, and resource utilization. Much of the technology required to meet these needs already exists, but an integrated structure that can demonstrate the potential for the technology in a concurrent engineering context does not. This book provides a road map for building the integrated technology environment to evaluate existing products, manufacturing processes and system design tools. This book details innovative approaches that will significantly improve design/manufacturing technology development and deploy ment capabilities for civilian and defense applications. These approaches are integrated product, process, and system design (IPPSD) initiatives which will greatly enhance the manufacturing competitiveness of the economy. These approaches involve the use of simulation, modeling tools and computerized virtual workstations in conjunction with a design environment which allows a diverse group of researchers, manufacturers, and suppliers to work within a comprehensive network of shared knowledge. The IPPSD infrastructure consists of virtual workstations, servers and a suite of simulation, quantitative, computa tional, analytical, experimental and qualitative tools. Such an IPPSD infrastructure will permit effective and efficient predictions of complete product design, manufacturing proces design, and customer satisfac tion.

Download or read book Design of Flexible Production Systems written by Tullio Tolio and published by Springer Science & Business Media. This book was released on 2008-12-11 with total page 308 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the last decade, the production of mechanical components to be assembled in final products produced in high volumes (e.g. cars, mopeds, industrial vehicles, etc.) has undergone deep changes due to the overall modifications in the way companies compete. Companies must consider competitive factors such as short lead times, tight product tolerances, frequent market changes and cost reduction. Anyway, companies often have to define production objectives as trade-offs among these critical factors since it can be difficult to improve all of them. Even if system flexibility is often considered a fundamental requirement for firms, it is not always a desirable characteristic of a system because it requires relevant investment cost which can jeopardize the profitability of the firm. Dedicated systems are not able to adapt to changes of the product characteristics while flexible systems offer more flexibility than what is needed, thus increasing investment and operative costs. Production contexts characterized by mid to high demand volume of well identified families of products in continuous evolution do not require the highest level of flexibility; therefore, manufacturing system flexibility must be rationalized and it is necessary to find out the best trade-off between productivity and flexibility by designing manufacturing systems endowed with the right level of flexibility required by the production problem. This new class of production systems can be named Focused Flexibility Manufacturing Systems-FFMSs. The flexibility degree in FFMSs is related to their ability to cope with volume, mix and technological changes, and it must take into account both present and future changes. The required level of system flexibility impacts on the architecture of the system and the explicit design of flexibility often leads to hybrid systems, i.e. automated integrated systems in which parts can be processed by both general purpose and dedicated machines. This is a key issue of FFMSs and results from the matching of flexibility and productivity that respectively characterize FMSs and Dedicated Manufacturing Systems (DMSs). The market share of the EU in the machine tool sector is 44%; the introduction of focused flexibility would be particularly important for machine tool builders whose competitive advantage is based on the ability of customizing their systems on the basis of needs of their customers. In fact, even if current production contexts frequently present situations which would fit well with the FFMS approach, tradition and know-how of machine tool builders play a crucial role. Firms often agree with the focused flexibility vision, nevertheless they decide not to pay the risk and efforts related to the design of this new system architecture. This is due also to the lack of well-structured design approaches which can help machine tool builders to configure innovative systems. Therefore, the FFMS topic is studied through the book chapters following a shared mission: "To define methodologies and tools to design production systems with a minimum level of flexibility needed to face, during their lifecycle, the product and process evolution both in the technological and demand aspects. The goal is to find out the optimal trade-off between flexibility and productivity". The book framework follows the architecture which has been developed to address the FFMS Design problem. This architecture is both broad and detailed, since it pays attention to all the relevant levels in a firm hierarchy which are involved in the system design. Moreover, the architecture is innovative because it models both the point of view of the machine tool builder and the point of view of the system user. The architecture starts analyzing Manufacturing Strategy issues and generating the possible demand scenario to be faced. Technological aspects play a key role while solving process plan problems for the products in the part family. Strategic and technological data becomes input when a machine tool builder performs system configuration. The resulting system configurations are possible solutions that a system user considers when planning its system capacity. All the steps of the architecture are deeply studied, developing methods and tools to address each subproblem. Particular attention is paid to the methodologies adopted to face the different subproblems: mathematical programming, stochastic programming, simulation techniques and inverse kinematics have been used. The whole architecture provides a general approach to implement the right degree of flexibility and it allows to study how different aspects and decisions taken in a firm impact on each other. The work presented in the book is innovative because it gives links among different research fields, such as Manufacturing Strategy, Process Plan, System Design, Capacity Planning and Performance Evaluation; moreover, it helps to formalize and rationalize a critical area such as manufacturing system flexibility. The addressed problem is relevant at an academic level but, also, at an industrial level. A great deal of industrial sectors need to address the problem of designing systems with the right degree of flexibility; for instance, automotive, white goods, electrical and electronic goods industries, etc. Attention to industrial issues is confirmed by empirical studies and real case analyses which are presented within the book chapters.
