    Each chapter utilizes case studies and numerous examples. Mathematical and technical sections can be skipped without loss of continuity. Most textbooks do not include models and decision support systems robust enough for industry, but that is not true of this new edition.The accompanying CD-ROM also features the return of two simulations, the Computerized Beer Game and the Risk Pool Game and a computerized tool. These simulations help users develop and execute supply chain contracts while also illustrating many of the concepts discussed in the text.

    This guide, which can be used with any text or can stand alone, contains at the beginning of each chapter a list of key definitions, a summary of major concepts, step by step solutions to dozens of problems, and additional practice problems.

    She came from what is perhaps the world's most mysterious and imaginatively-crafted chess set -- 73 carved pieces probably dating to the 1200's. The famous Chess men (and women) comprise the world's oldest complete chess set (or parts of several sets). The treasure trove was discovered 15 feet deep in the sand in Lewis in Scotland's northern Outer Hebrides in the late 19th century. Scandinavian outposts were known to be there as early as the 1200's when the pieces were probably crafted. That chess was played in the Middle Ages with such extraordinary works of art tantalizes the imagination. Who were these people whose likenesses have been so whimsically and realistically depicted that they come alive for us today? Who played the game? These kings and queens, bishops with miters on their heads, knights mounted on rather small horses and holding spears and shields, rooks with shields and a wild expression, and pawns in the shape of obelisks -- all so very human. Some of the pieces contain red stains, suggesting perhaps that the sets had some colorings unlike modern black and white pieces. "This is the first forensic account of modern research into the Chessmen," according to Ancientchess.com. The "unmasked" in the book's title refers to new controversies about their origin and about who might have owned - and lost - them - and about the trade and state of society where they were crafted.

    In its most simple form, earned value equates to fundamental project management. This is not a new book, but rather it is an updated book. Authors Quentin Fleming and Joel Koppelman have made some important additions. In many cases, there will be no changes to a given section. But in other sections, the authors have made substantial revisions to what they had described in the first edition. Fleming and Koppelman’s goal remains the same with this update: describe earned value project management in its most fundamental form, for application to all projects, of any size or complexity. Writing in an easy-to-read, friendly, and humorous style characteristic of the best teachers, Fleming and Koppelman have identified the minimum requirements that they feel are necessary to use earned value as a simple tool for project managers. They have also witnessed the use of simple earned value on software projects, and find it particularly exciting. Realistically, a Cost Performance Index (CPI) is the same whether the project is a multibillion-dollar high-technology project, or a simple one hundred thousand-dollar software project. A CPI is a CPI … period. It is a solid metric that reflects the health of the project. In every chapter, Fleming and Koppelman stick with using simple stories to define their central concept. Their project examples range from peeling potatoes to building a house. Examples are in round numbers, and most formulas get no more complicated than one number divided by another. Earned Value Project Management—Second Edition may be the best-written, most easily understood project management book on the market today. Project managers will welcome this fresh translation of jargon into ordinary English. The authors have mastered a unique "early-warning" signal of impending cost problems in time for the project manager to react.

    While not nearly as much in demand today as they were in the days of the Yankee clippers, these skills nevertheless remain important and necessary to today's yachtsmen and owners of smaller pleasure boats.In this excellent handbook on basic shipboard skills, marine expert Hervey Garrett Smith offers boating and yachting enthusiasts a complete course in rigging, working, and maintaining a ship. More than 100 illustrations help the reader grasp the fundamentals and fine points of handling a ship while the author describes in detail a sailor's tools, basic knots, and useful hitches as well as the arts of splicing, handsewing, and canvas work.Other topics equally important to safe, economical, and efficient boat maintenance and management include belaying, coiling, and stowing; towing procedures; how to make a chafing gear; and much more. Easy-to-follow instructions for fashioning decorative knots, ornamental coverings, and nettings, and even how to make a proper bucket round out this engaging and informative guide.Packed with useful "hands-on" information conveyed in a chatty, humorous style, The Arts of the Sailor is the perfect book to keep aboard ship for study and for ready reference when the need arises. It also makes delightful reading for armchair sailors and the legions of landlubbers with an interest in the sea.

    It runs on PCs rather than servers and is ideal for small- to mid-sized businesses and households. But Access is still intimidating to learn. It doesn't help that each new version crammed in yet another set of features; so many, in fact, that even the pros don't know where to find them all. Access 2007 breaks this pattern with some of the most dramatic changes users have seen since Office 95. Most obvious is the thoroughly redesigned user interface, with its tabbed toolbar (or "Ribbon") that makes features easy to locate and use. The features list also includes several long-awaited changes. One thing that hasn't improved is Microsoft's documentation. To learn the ins and outs of all the features in Access 2007, Microsoft merely offers online help.Access 2007: The Missing Manual was written from the ground up for this redesigned application. You will learn how to design complete databases, maintain them, search for valuable nuggets of information, and build attractive forms for quick-and-easy data entry. You'll even delve into the black art of Access programming (including macros and Visual Basic), and pick up valuable tricks and techniques to automate common tasks -- even if you've never touched a line of code before. You will also learn all about the new prebuilt databases you can customize to fit your needs, and how the new complex data feature will simplify your life. With plenty of downloadable examples, this objective and witty book will turn an Access neophyte into a true master.

    Each mini-chapter adds one feature to the ray tracer, and by the end the reader can produce the image on the book cover. Details of basic ray tracing code architecture and C++ classes are given.

    Capablanca was a World Chess Champion and one of the greatest players in chess history, yet he wrote very little about the game. Chess Fundamentals, though normally for the beginning player, contains valuable insights that will benefit players at all levels of understanding, including masters. Capablanca explains:·How to obtain and nurture a passed pawn·How to get and keep the initiative·Cardinal rules for rook and pawn endings·How to attack using knight as the main force·How to cut off enemy piecesChess Fundamentals is one of the jewels of chess literature.
