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

Book Synopsis Flexibility in Engineering Design by : Richard De Neufville

Download or read book Flexibility in Engineering Design written by Richard De Neufville. This book was released on 2011-08-12. 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 Synopsis Design for Flexibility by : Guy André Boy

Download or read book Design for Flexibility written by Guy André Boy. This book was released on 2021-06-19. 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.

Book Synopsis Human–Systems Integration by : Guy André Boy

Download or read book Human–Systems Integration written by Guy André Boy. This book was released on 2020-01-27. Available in PDF, EPUB and Kindle. 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.

Book Synopsis Flexible Housing by : Jeremy Till

Download or read book Flexible Housing written by Jeremy Till. This book was released on 2016-09-19. Available in PDF, EPUB and Kindle. Book excerpt: Flexible housing is housing that can adjust to the changing needs of the user and accommodate new technologies as they emerge. Flexible Housing by Jeremy Till and Tatjana Schneider examines the past, present and future of this important subject through over 160 international examples. Specially commissioned plans, printed to scale, together with over 200 illustrations and diagrams provide fascinating detail and allow direct visual comparisons to be made. Combining history, theory and design the book explains the social and economic benefits that can be achieved and shows the various ways it has been and can be delivered. The book ends with an accessible guide to how flexible housing might be designed and constructed today to achieve adaptable and ultimately sustainable buildings. Housing designers, housing managers and students of architecture, construction and housing will find this book of immense value both as a comprehensive reference and design manual.
