Available in PDF, EPUB and Kindle. Book excerpt: Strategies for building large systems that can be easily adapted for new situations with only minor programming modifications. Time pressures encourage programmers to write code that works well for a narrow purpose, with no room to grow. But the best systems are evolvable; they can be adapted for new situations by adding code, rather than changing the existing code. The authors describe techniques they have found effective--over their combined 100-plus years of programming experience--that will help programmers avoid programming themselves into corners. The authors explore ways to enhance flexibility by: Organizing systems using combinators to compose mix-and-match parts, ranging from small functions to whole arithmetics, with standardized interfaces Augmenting data with independent annotation layers, such as units of measurement or provenance Combining independent pieces of partial information using unification or propagation Separating control structure from problem domain with domain models, rule systems and pattern matching, propagation, and dependency-directed backtracking Extending the programming language, using dynamically extensible evaluators

Available in PDF, EPUB and Kindle. Book excerpt: Design for flexibility requires anticipation, preparation, creativity and experience. Future highly digital sociotechnical systems should contrast with those stemming from technology-centered engineering that produces objects and machines with the immensely codified and rigid practices we know today. Most of the time, current technologies are designed and developed for normal situations, leaving users to manage abnormal and emergency situations themselves, sometimes under unforeseen, extreme and/or dangerous conditions. Putting humans at the center of the design of flexible sociotechnical systems means visualizing possible futures, modeling them, simulating them and leading them down the right paths. This book is for the engineering designers, who seek to better understand the roles of humans and organizations developing complex life-critical systems. It is also for those who train future designers who will have to take into account the well-being, safety, sustainability and efficiency of the actors of future sociotechnical systems. It is about an emergent discipline, human systems integration (HSI). The aim of the flexibility challenge is to put the artificial at the service of the natural, and not the other way around. The author, an aerospace engineering designer, has worked for 40 years in the field of human-centered design (HCD) of complex systems, discovering repeatedly that automation leads to rigidity, especially when things go wrong. It is urgent we had a new paradigm where flexibility is a major asset in human systems integration. HCD is seen here as the combination of practices and technologies to come.

Download or read book Flexibility in Engineering Design written by Richard De Neufville and published by MIT Press. This book was released on 2011-08-12 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: A guide to using the power of design flexibility to improve the performance of complex technological projects, for designers, managers, users, and analysts. Project teams can improve results by recognizing that the future is inevitably uncertain and that by creating flexible designs they can adapt to eventualities. This approach enables them to take advantage of new opportunities and avoid harmful losses. Designers of complex, long-lasting projects—such as communication networks, power plants, or hospitals—must learn to abandon fixed specifications and narrow forecasts. They need to avoid the “flaw of averages,” the conceptual pitfall that traps so many designs in underperformance. Failure to allow for changing circumstances risks leaving significant value untapped. This book is a guide for creating and implementing value-enhancing flexibility in design. It will be an essential resource for all participants in the development and operation of technological systems: designers, managers, financial analysts, investors, regulators, and academics. The book provides a high-level overview of why flexibility in design is needed to deliver significantly increased value. It describes in detail methods to identify, select, and implement useful flexibility. The book is unique in that it explicitly recognizes that future outcomes are uncertain. It thus presents forecasting, analysis, and evaluation tools especially suited to this reality. Appendixes provide expanded explanations of concepts and analytic tools.

Book excerpt: Human–Systems Integration: From Virtual to Tangible Subject Guide: Ergonomics and Human Factors This book is an attempt to better formalize a systemic approach to human–systems integration (HSI). Good HSI is a matter of maturity... it takes time to mature. It takes time for a human being to become autonomous, and then mature! HSI is a matter of human–machine teaming, where human–machine cooperation and coordination are crucial. We cannot think engineering design without considering people and organizations that go with it. We also cannot think new technology, new organizations, and new jobs without considering change management. More specifically, this book is a follow-up of previous contributions in human-centered design and practice in the development of virtual prototypes that requires progressive operational tangibility toward HSI. The book discusses flexibility in design and operations, tangibility of software-intensive systems, virtual human-centered design, increasingly autonomous complex systems, human factors and ergonomics of sociotechnical systems, systems integration, and changed management in digital organizations. The book will be of interest to industry, academia, those involved with systems engineering, human factors, and the broader public.

Download or read book A Guide for Achieving Flexibility in Highway Design written by and published by AASHTO. This book was released on 2004 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: Context-sensitive solutions (CSS) reflect the need to consider highway projects as more than just transportation facilities. Depending on how highway projects are integrated into the community, they can have far-reaching impacts beyond their traffic or transportation function. CSS is a comprehensive process that brings stakeholders together in a positive, proactive environment to develop projects that not only meet transportation needs, but also improve or enhance the community. Achieving a flexible, context-sensitive design solution requires designers to fully understand the reasons behind the processes, design values, and design procedures that are used. This AASHTO Guide shows highway designers how to think flexibly, how to recognize the many choices and options they have, and how to arrive at the best solution for the particular situation or context. It also strives to emphasize that flexible design does not necessarily entail a fundamentally new design process, but that it can be integrated into the existing transportation culture. This publication represents a major step toward institutionalizing CSS into state transportation departments and other agencies charged with transportation project development.

Available in PDF, EPUB and Kindle. Book excerpt: strategy, but we also focus on execution. We talk about organizational design, and also refect on leadership practices. Our assumption is that in a dynamic world, leaders at all levels, have to constantly switch gears, wear different hats, and na- gate at different altitudes. They have to think about the “total” enterprise, not in terms of compartmentalized silos or felds of functional expertise. Much like a g- eral contractor, they have to draw on specialized expertise, as and when needed, yet keep the big picture in mind. Our hope is that our diagnostic tools can help teams develop a shared frame of reference and generate cross-functional dialogue. The third driving force behind this second edition is the gradual convergence between the worlds of entrepreneurial start-ups and challenges facing established corporations. Innovation, agility, and initiative are no longer the exclusive preserve of start-ups. Established companies are looking for ways to re-invent themselves, to innovate, to think creatively, and to make their enterprises more fexible, agile and entrepreneurial. We have had the good fortune to sit at the intersection of these two worlds. We hope our ideas can beneft both groups. We set out to provide a “buffet table”, a menu of options that can be helpful for the two ends of the spectrum.

Download or read book Grow Home written by Avi Friedman and published by McGill-Queen's Press - MQUP. This book was released on 2001-02-09 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: With economic restructuring, demographic shifts, and lifestyle changes, the traditional family - working father, stay-at-home mother, two to three children - is no longer the norm and the need for smaller homes at moderate cost has skyrocketed. The first prototype of the Grow Home was built on the campus of McGill University in 1990 and more than one thousand units were built across North America and Europe in the first year alone. In this illustrated guide, Friedman describes the background, conception, and construction of these modest (14" x 36") homes. He details their construction for prospective owners, builders, and architects, showing how past and contemporary precedents have been transformed and how the first versions were adapted by the building industry. Visits to completed Grow Homes shed light on why such homes were purchased and the process by which they "grew." Friedman also shows how the design has been adapted for prefabrication to meet the needs of the developing world. He describes the contribution that small-unit design makes to saving valuable natural resources and shares his experiences in planning communities based on the Grow Home. The Grow Home reveals the development and history of a concept that revolutionizes the home and building industry, has been translated into over 10,000 housing units, and has received, among many accolades, the United Nations World Habitat Award.

Download or read book Optimizing Higher Education Learning Through Activities and Assessments written by Inoue-Smith, Yukiko and published by IGI Global. This book was released on 2020-06-26 with total page 407 pages. Available in PDF, EPUB and Kindle. Book excerpt: The mission of higher education in the 21st century must focus on optimizing learning for all students. In a shift from prioritizing effective teaching to active learning, it is understood that computer-enhanced environments provide a variety of ways to reach a wide range of learners who have differing backgrounds, ages, learning needs, and expectations. Integrating technology into teaching assumes greater importance to improve the learning experience. Optimizing Higher Education Learning Through Activities and Assessments is a collection of innovative research that explores the link between effective course design and student engagement and optimizes learning and assessments in technology-enhanced environments and among diverse student populations. Its focus is on providing an understanding of the essential link between practices for effective “activities” and strategies for effective “assessments,” as well as providing examples of course designs aligned with assessments, positioning college educators both as leaders and followers in the cycle of lifelong learning. While highlighting a broad range of topics including collaborative teaching, active learning, and flipped classroom methods, this book is ideally designed for educators, curriculum developers, instructional designers, administrators, researchers, academicians, and students.

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.

Download or read book Deterministic Flexibility Analysis written by Chuei-Tin Chang and published by CRC Press. This book was released on 2017-07-28 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Traditionally, design and control decisions are made in sequential stages over the life cycle of a chemical plant. In the design phase, the optimal operating conditions and the corresponding material and energy balance data are established mainly on the basis of economic considerations. In the subsequent step, the control systems are configured to maintain the key process conditions at the fixed nominal values. Because it is often desirable to address the operability issues at the earliest possible stage before stipulation of control schemes, the systematic incorporation of flexibility analysis in process synthesis and design has received considerable attention in recent years. This book focuses to a large extent on computation and implementation methods of deterministic performance measures, i.e., the steady-state, volumetric, dynamic and temporal flexibility indices, in various applications. The formal definitions of several available performance indices, their mathematical formulations, and the corresponding algorithms and codes are provided in sufficient detail to facilitate implementation. To show the utility of flexibility analyses, the book presents several practical case studies including membrane modules and heat-exchanger networks, solar-driven membrane distillation desalination systems, and hybrid power generation systems. It also includes MATLAB and GAMS codes.
