Question

Starlight Coffee shop at the Galleria Mall serves two coffee blends it brews on a daily basis, Pomona and Coastal. Each is a blend of three high quality coffees from Columbia, Kenya, and Indonesia. The coffee shop has ten pounds of each coffee available each day.. Each pound of coffee will produce sixteen 16-ounce cups of coffee. The shop has enough brewing capacity to brew 30 gallons of these two coffee blends each day. Pomona is a blend of 20% Columbian, 35% Kenyan, and 45% Indonesian, while Coastal is a blend of 60% Columbian, 10% Kenyan, and 30% Indonesian. The shop sells 1.5 times more Pomona than Coastal each day. Pomona sells for $2.05 per cup, and Coastal sells for $1.85 per cup. The manager wants to know how many cups of each blend to sell each day in order to maximize sales.

Explanation / Answer

QM for Windows Software Package QM for Windows is a computer package that is included on the text Companion Web site, and many students and instructors will prefer to use it with this text. This software is very user friendly, requiring virtually no preliminary instruction except for the “help” screens that can be accessed directly from the program. It is demonstrated throughout the text in conjunction with virtually every management science modeling technique, except simulation. The text includes 50 QM for Windows screens used to demonstrate example problems. Thus, for most topics problem solution is demonstrated via both Excel spreadsheets and QM for Windows. Files that include all the QM for Windows solutions for examples in the text are included on the accompanying Companion Web site. Following is an example of one of the QM for Windows files (from Chapter 4) that is on the Companion Web site. Microsoft Project As we indicated previously, when talking about the new features in this edition, Chapter 8 on project management includes the popular software package Microsoft Project. Following on the next page is an example of one of the Microsoft Project files (from Chapter 8) that is available on the text Companion Web site. Crystal Ball Still another spreadsheet add-in program is Crystal Ball by Oracle. Crystal Ball is demonstrated in Chapter 14 on simulation and shows how to perform simulation analysis for certain types of risk analysis and forecasting problems. Following is an example of one of the Crystal Ball files (from Chapter 14) that is on the Companion Web site. Using the access code, found on the inside front cover of this book, you can download a 140-day trial version of this software for free. PREFACE xv New Problems and Cases Previous editions of the text always provided a substantial number of homework questions, problems, and cases to offer students practice. This edition includes more than 800 homework problems, 55 of which are new, and 64 end-of-chapter cases, 2 of which are new. In addition, 4 additional spreadsheet modeling cases are provided on the Companion Web site. “Management Science Application” Boxes These boxes are located in every chapter in the text. They describe how a company, an organization, or an agency uses the particular management science technique being presented and demonstrated in the chapter to compete in a global environment. There are 52 of these boxes, 16 of which are new, throughout the text. They encompass a broad range of business and public-sector applications, both foreign and domestic. Marginal Notes Notes in the margins of this text serve the same basic function as notes that students themselves might write in the margin. They highlight certain topics to make it easier for students to locate them, summarize topics and important points, and provide brief definitions of key terms and concepts. Examples The primary means of teaching the various quantitative modeling techniques presented in this text is through examples. Thus, examples are liberally inserted throughout the text, primarily to demonstrate how problems are solved with the different quantitative techniques and to make them easier to understand. These examples are organized in a logical step-by-step solution approach that the student can subsequently apply to the homework problems. Solved Example Problems At the end of each chapter, just prior to the homework questions and problems, is a section that provides solved examples to serve as a guide for doing the homework problems. These examples are solved in a detailed, stepby-step fashion. New Chapter Web Links A new feature in this edition is a file on the Companion Web site that contains Chapter Web links for every chapter in the text. These Web links access tutorials, summaries, and notes available on the Internet for the various techniques and topics in every chapter in the text. Also included are YouTube videos that provide additional learning resources and tutorials about many of the topics and techniques, links to the development and developers of the techniques in the text, and links to the Web sites for the companies and organizations that are featured in the “Management Science Application” boxes in every chapter. The “Chapter Web links” file includes more than 550 Web links.
