Our socio-economic systems continue to grow and evolve. We need to acknowledge that, consequently, our decisions often fail – they are ineffective and create unexpected side effects. The speed of execution is increasing constantly and markets and systems respond almost immediately, making decision-making challenging. There is little or no room for failure.This important new book analyses real world strategy and policy challenges, addressing the interconnectedness of the markets/systems we live in. It provides a step-by-step approach using systems thinking to solve complex problems in socio-political as well as business environment. It proposes a technique with which to better understand the problems and the context in which they arise, and tools to directly inform each step of the decision-making process. The book explores the main innovation that systemic thinking introduces – the emphasis on defining the problem creating system, which is made up of interacting parts, rather than prioritizing events that need immediate fixing.The case studies, examples and the approach proposed can be used to better understand reality and its complexity, and to integrate stakeholders for a better solution. Practically, it can be used to identify problems, analyse their boundaries, design interventions, forecast and measure their expected impacts, implement them and monitor and evaluate their success/failure. The book touches upon global issues related to policy making and strategic management, as well as issues related to sustainable development for both the public and private sector.

INTRODUCTION We start this book with Theme A (see Figure P. I in the Preface), which aims to develop an essential and fundamental understanding of systems science. So, what is systems science? When asked to explain what systems science is all about, many systems scientists are confronted with a rather daunting task. The discipline tends to be presented and understood in a fragmented way and very few people hold an overview understanding of the subject matter, while also having sufficient in-depth competence in many and broad-ranging subject areas where the ideas are used. Indeed, it was precisely this difficulty that identified the need for a comprehensive well-documented account such as is presented here in Dealing with Complexity.

You want increased customer satisfaction, faster development cycles, and less wasted work. Domain-driven design (DDD) combined with functional programming is the innovative combo that will get you there. In this pragmatic, down-to-earth guide, you'll see how applying the core principles of functional programming can result in software designs that model real-world requirements both elegantly and concisely - often more so than an object-oriented approach. Practical examples in the open-source F# functional language, and examples from familiar business domains, show you how to apply these techniques to build software that is business-focused, flexible, and high quality. Domain-driven design is a well-established approach to designing software that ensures that domain experts and developers work together effectively to create high-quality software. This book is the first to combine DDD with techniques from statically typed functional programming. This book is perfect for newcomers to DDD or functional programming - all the techniques you need will be introduced and explained. Model a complex domain accurately using the F# type system, creating compilable code that is also readable documentation---ensuring that the code and design never get out of sync. Encode business rules in the design so that you have "compile-time unit tests," and eliminate many potential bugs by making illegal states unrepresentable. Assemble a series of small, testable functions into a complete use case, and compose these individual scenarios into a large-scale design. Discover why the combination of functional programming and DDD leads naturally to service-oriented and hexagonal architectures. Finally, create a functional domain model that works with traditional databases, NoSQL, and event stores, and safely expose your domain via a website or API. Solve real problems by focusing on real-world requirements for your software. What You Need: The code in this book is designed to be run interactively on Windows, Mac and Linux.You will need a recent version of F# (4.0 or greater), and the appropriate .NET runtime for your platform.Full installation instructions for all platforms at fsharp.org.

The Department for Work and Pensions (DWP) and its agencies, are responsible for administering around 40 social security benefits to the value of around £100 billion a year. Many of these benefits are linked together; hence some customers are in receipt of more than one benefit. The need for equity and fairness in interpreting legislation, is a cause of complexity. Incentives (e.g. to work) and rewards (e.g. for an individual's savings) have been built into procedures. Problems are caused by the interface between DWP benefits and tax credits (which are administered by HM Revenue and Customs); and by the constant flow of major and minor legislative and administrative changes. Simplified procedures would enable both staff and customers to understand the system better, and to avoid duplication of effort. There would also be less scope for benefits fraud (estimated at £2.6 billion in 2004-05). This NAO report also highlights the need for improved communication with customers and better use of new technology.

Domain-Driven Design (DDD) is an approach to software development for complex businesses and other domains. DDD tackles that complexity by focusing the team's attention on knowledge of the domain, picking apart the most tricky, intricate problems with models, and shaping the software around those models. Easier said than done! The techniques of DDD help us approach this systematically. This reference gives a quick and authoritative summary of the key concepts of DDD. It is not meant as a learning introduction to the subject. Eric Evans' original book and a handful of others explain DDD in depth from different perspectives. On the other hand, we often need to scan a topic quickly or get the gist of a particular pattern. That is the purpose of this reference. It is complementary to the more discursive books. The starting point of this text was a set of excerpts from the original book by Eric Evans, Domain-Driven-Design: Tackling Complexity in the Heart of Software, 2004 - in particular, the pattern summaries, which were placed in the Creative Commons by Evans and the publisher, Pearson Education. In this reference, those original summaries have been updated and expanded with new content. The practice and understanding of DDD has not stood still over the past decade, and Evans has taken this chance to document some important refinements. Some of the patterns and definitions have been edited or rewritten by Evans to clarify the original intent. Three patterns have been added, describing concepts whose usefulness and importance has emerged in the intervening years. Also, the sequence and grouping of the topics has been changed significantly to better emphasize the core principles. This is an up-to-date, quick reference to DDD.

Solve complex business problems by understanding users better, finding the right problem to solve, and building lean event-driven systems to give your customers what they really want Key FeaturesApply DDD principles using modern tools such as EventStorming, Event Sourcing, and CQRSLearn how DDD applies directly to various architectural styles such as REST, reactive systems, and microservicesEmpower teams to work flexibly with improved services and decoupled interactionsBook Description Developers across the world are rapidly adopting DDD principles to deliver powerful results when writing software that deals with complex business requirements. This book will guide you in involving business stakeholders when choosing the software you are planning to build for them. By figuring out the temporal nature of behavior-driven domain models, you will be able to build leaner, more agile, and modular systems. You'll begin by uncovering domain complexity and learn how to capture the behavioral aspects of the domain language. You will then learn about EventStorming and advance to creating a new project in .NET Core 2.1; you'll also and write some code to transfer your events from sticky notes to C#. The book will show you how to use aggregates to handle commands and produce events. As you progress, you'll get to grips with Bounded Contexts, Context Map, Event Sourcing, and CQRS. After translating domain models into executable C# code, you will create a frontend for your application using Vue.js. In addition to this, you'll learn how to refactor your code and cover event versioning and migration essentials. By the end of this DDD book, you will have gained the confidence to implement the DDD approach in your organization and be able to explore new techniques that complement what you've learned from the book. What you will learnDiscover and resolve domain complexity together with business stakeholdersAvoid common pitfalls when creating the domain modelStudy the concept of Bounded Context and aggregateDesign and build temporal models based on behavior and not only dataExplore benefits and drawbacks of Event SourcingGet acquainted with CQRS and to-the-point read models with projectionsPractice building one-way flow UI with Vue.jsUnderstand how a task-based UI conforms to DDD principlesWho this book is for This book is for .NET developers who have an intermediate level understanding of C#, and for those who seek to deliver value, not just write code.

Compared to its widespread implementation across almost all areas of production, Lean improvement efforts lag within the process industries. While many innovators have successfully applied Lean principles to these industries during the past three decades, most of those pioneering efforts were never recorded to guide the improvement efforts of others. Drawing on more than 40 years of application experience at one of the world’s largest chemical and materials manufacturers, coupled with 10 years in private practice, Peter King corrects this void by providing the first comprehensive resource written explicitly for change agents within the process industries. Focusing on areas where the improvement needs of the process industry differ from parts assembly manufacturing, Lean for the Process Industries: Dealing with Complexity, Second Edition: Covers each of the eight wastes commonly described in Lean literature, looking at how they manifest themselves in process operations. Explains how to adapt value stream mapping for process operations. Shows how to identify the root causes of bottlenecks, and how to manage them to optimize flow until they can be eliminated. Provides practical techniques to overcome the barriers which have prevented the application of Cellular Manufacturing to process operations. Discusses the role of business leadership in a Lean strategy, describing both enabling and counter-productive management behaviors Since the publication of the first edition of this book, Peter King has been busy consulting with food, beverage, gasoline additive, and nutraceutical companies -- these new experiences have broadened his perspectives on certain Lean processes and have given him a richer set of examples to discuss in this new edition. While Value Stream Mapping is a very powerful tool to understand flow, bottlenecks, and waste in an operation, the traditional format as presented in many other books does not describe all of the data required to fully understand process flow and its detractors. This new edition highlights the necessary additions with examples of why they are useful. Product wheel scheduling achieves production leveling in a far more comprehensive and effective way than traditional heijunka methods. This edition has a more thorough description of the wheel concept and design steps, and more examples from actual applications.

"Every developer working with the Web needs to read this book." -- David Heinemeier Hansson, creator of the Rails framework "RESTful Web Services finally provides a practical roadmap for constructing services that embrace the Web, instead of trying to route around it." -- Adam Trachtenberg, PHP author and EBay Web Services Evangelist You've built web sites that can be used by humans. But can you also build web sites that are usable by machines? That's where the future lies, and that's what RESTful Web Services shows you how to do. The World Wide Web is the most popular distributed application in history, and Web services and mashups have turned it into a powerful distributed computing platform. But today's web service technologies have lost sight of the simplicity that made the Web successful. They don't work like the Web, and they're missing out on its advantages. This book puts the "Web" back into web services. It shows how you can connect to the programmable web with the technologies you already use every day. The key is REST, the architectural style that drives the Web. This book: Emphasizes the power of basic Web technologies -- the HTTP application protocol, the URI naming standard, and the XML markup language Introduces the Resource-Oriented Architecture (ROA), a common-sense set of rules for designing RESTful web services Shows how a RESTful design is simpler, more versatile, and more scalable than a design based on Remote Procedure Calls (RPC) Includes real-world examples of RESTful web services, like Amazon's Simple Storage Service and the Atom Publishing Protocol Discusses web service clients for popular programming languages Shows how to implement RESTful services in three popular frameworks -- Ruby on Rails, Restlet (for Java), and Django (for Python) Focuses on practical issues: how to design and implement RESTful web services and clients This is the first book that applies the REST design philosophy to real web services. It sets down the best practices you need to make your design a success, and the techniques you need to turn your design into working code. You can harness the power of the Web for programmable applications: you just have to work with the Web instead of against it. This book shows you how.

"Structural unemployment, alarming changes in the environment, periodical signs of an imminent Stock Exchange crash, involvement in armed conflicts: we are faced with an increasingly complex world and the inadequacy of conventional ways of thinking is becoming progressively more evident. Although perfectly planned in itself, the consequences of any intervention to the intricate fabric can have fatal repercussions: feedbacks, time delays and delayed after-effects."--Back cover.

Contemporary Systems Thinking is a series of texts, each of which deals comparatively and/or critically with different aspects of holistic thinking at the frontiers of the discipline. Traditionally, writings by systems thinkers have been concerned with single theme propositions such as general systems theory, cybernetics, operations research, system dyna mics, soft systems methodology, and many others. Recently there have been attempts to fulfil a different, yet equally important, role by com parative analyses of viewpoints and approaches, each addressing dispa rate areas of study such as modeling and simulation, measurement, management, "problem-solving" methods, international relations, so cial theory, and last, but not exhaustively or least, philosophy. In a recent book these were drawn together within a multiform framework as part of an eclectic discussion-a nearly impossible task as I dis covered (see Dealing with Complexity-An Introduction to the Theory and Application of Systems Science by R. L. Flood and E. R. Carson). Neverthe less, bringing many sources together led to several achievements, among which was showing a great diversity of approaches, ideas, and application areas that systems thinking contributes to (although often with difficulties remaining unresolved). More important, however, while working on that manuscript I became aware of the need for and potential value in a series of books, each focusing in detail on the study areas mentioned above.

From climate change to GM foods, we are increasingly confronted with complex, interconnected social and environmental problems that span disciplines, knowledge bases and value systems. This book offers a transdisciplinary, open approach for those working towards resolving these 'wicked' problems and highlights the crucial role of this 'transdisciplinary imagination' in addressing the shift to sustainable futures. Tackling Wicked Problems provides readers with a framework and practical examples that will guide the design and conduct of their own open-ended enquiries. In this approach, academic disciplines are combined with personal, local and strategic understanding and researchers are required to recognise multiple knowledge cultures, accept the inevitability of uncertainty, and clarify their own and others' ethical positions. The authors then comment on fifteen practical examples of how researchers have engaged with the opportunities and challenges of conducting transdisciplinary inquiries. The book gives those who are grappling with complex problems innovative methods of inquiry that will allow them to work collaboratively towards long-term solutions.

The purpose of this annual series, Applied and Computational Control, Signals, and Circuits, is to keep abreast of the fast-paced developments in computational mathematics and scientific computing and their increasing use by researchers and engineers in control, signals, and circuits. The series is dedicated to fostering effective communication between mathematicians, computer scientists, computational scientists, software engineers, theorists, and practicing engineers. This interdisciplinary scope is meant to blend areas of mathematics (such as linear algebra, operator theory, and certain branches of analysis) and computational mathematics (numerical linear algebra, numerical differential equations, large scale and parallel matrix computations, numerical optimization) with control and systems theory, signal and image processing, and circuit analysis and design. The disciplines mentioned above have long enjoyed a natural synergy. There are distinguished journals in the fields of control and systems the ory, as well as signal processing and circuit theory, which publish high quality papers on mathematical and engineering aspects of these areas; however, articles on their computational and applications aspects appear only sporadically. At the same time, there has been tremendous recent growth and development of computational mathematics, scientific comput ing, and mathematical software, and the resulting sophisticated techniques are being gradually adapted by engineers, software designers, and other scientists to the needs of those applied disciplines.
