OBJECTIVES
(a) To introduce students to the subject of Management Science, and a variety of manage-
ment science models, methods and computational procedures that are helpful in solving
management problems in Finance, P.O.M., Accounting, M.I.S., Marketing, Operational
Research, Actuarial Science, etc. Emphasis is placed on models and their solutions.
The course offers you a broad spectrum of knowledge of the mechanics of management
science techniques and the types of problems to which these techniques are applied. The
ultimate test of a management scientist or a manager who uses management science
techniques is the ability to transfer textbook knowledge to the business world.
(b) To give students a good foundation in basic problem solving as a preparation for upper
level quantitative courses (Finance, Production/ Operations Management, Accounting,
M.I.S., Marketing, Operational Research, Supply Chain Management etc.).

(c) Quantitative analysis is a scientific approach to decision making. The quantitative anal-
ysis approach includes defining the problem, developing a model, acquiring input data,
developing a solution, testing the solution, analyzing the results, and implementing the
results.
(d) To develop in students an appreciation of the management science approach to problem
formulation and solution, so important in the modern business and industrial world
with the increased use of computers. This course is designed to provide students with
a conceptual understanding of the role that management science plays in the decision-
making process. Quantitative methods will be discussed and there will be emphasis on
modeling, problem solving, and showing how quantitative approaches can be used in
decision making process.
(e) In the words of the authors. The objective of management science is to solve
the decision-making problems that confront and confound managers in both the public
and the private sector by developing mathematical models of those problems. These
models have traditionally been solved with various mathematical techniques, all of which
lend themselves to specific types of problems. Thus, management science as a field of
study has always been inherently mathematical in nature, and as a result sometimes
complex and rigorous. When I began writing the first edition of this book in 1979, my
main goal was to make these mathematical topics seem less complex and thus more
palatable to undergraduate business students. To achieve this goal I started out by
trying to provide simple, straightforward explanations of often difficult mathematical
topics. I tried to use lots of examples that demonstrated in detail the fundamental
mathematical steps of the modeling and solution techniques. Although in the last two
and a half decades the emphasis in management science has shifted away from strictly
mathematical to mostly computer solutions, my objective has not changed. I have
provided clear, concise explanations of the techniques used in management science to
model problems, and provided lots of examples of how to solve these models on the
computer, while still including some of the fundamental mathematics of the techniques.
The stuff of management science can seem abstract, and students sometimes have trou-
ble perceiving the usefulness of quantitative courses in general. I remember when I was
a student I could not foresee how I would use such mathematical topics (in addition to
a lot of the other things I learned in college) in any job after graduation. Part of the
problem is that the examples used in books often do not seem realistic. Unfortunately,
examples must be made simple to facilitate the learning process. Larger, more com-
3
-
plex examples reflecting actual applications would be too complex to help the student
learn the modeling technique. The modeling techniques presented in this text are, in
fact, used extensively in the business world and their use is increasing rapidly because
of computer and information technology. Therefore, the chances of students using the
modeling techniques that they learn from this text in a future job are very great indeed.
Even if these techniques are not used on the job, the logical approach to problem solving
embodied in management science is valuable for all types of jobs in all types of orga-
nizations. Management science consists of more than just a collection of mathematical
modeling techniques; it embodies a philosophy of approaching a problem in a logical
manner, as does any science. Thus, this text not only teaches specific techniques but
also provides a very useful method for approaching problems.
My primary objective throughout all revisions of this text is readability. The modeling
techniques presented in each chapter are explained with straightforward examples that
avoid lengthy written explanations. These examples are organized in a logical step-by-
step fashion that the student can subsequently apply to the Problems at the end of each
chapter. I have tried to avoid complex mathematical notation and formulas wherever
possible. These various factors will, I hope, help make the material more interesting
and less intimidating to students.

els of Cost, Revenue and Profit, Cost and Volume Models, Revenue and Volume
Models, Profit and Volume Models, BreakEven Analysis. In this chapter, the model
construction and solutions that constitute each management science technique will be
presented in detail and illustrated with examples. Components of Break-Even Analy-
sis are presented. The three components of break-even analysis are volume, cost, and
profit. Graphical illustration and profit analysis will be discussed.
• Chapter 3. An Introduction to Linear Programming pp.35-78, A Simple Maxi-

Solving Linear Programs with Excel. Linear programming models exhibit certain
common characteristics: An objective function to be maximized or minimized, A set
of constraints, Decision variables for measuring the level of activity, Linearity among
all constraint relationships and the objective function. The graphical approach is lim-
ited to models with only two decision variables. However, the analysis of the graphical
approach provides valuable insight into linear programming problems and their solu-
tions. In Chapter 4 we will show how linear programming solutions can be obtained
using computer programs such as Excel.
• Chapter 4. In this chapter pp.79-120 we will show how linear programming problems
can be solved using Excel computer software packages. We will also describe how to
use a computer solution result to experiment with a linear programming model to see
what effect parameter changes have on the optimal solution, referred to as sensitiv-
ity analysis. Students are also exposed to Excel formulation to linear programming
model. Sensitivity Analysis and Interpretation of Solution, Introduction to Sensitiv-
ity Analysis, Objective Function Coefficients Right-Hand Sides Sensitivity Analysis,

• Chapter 5 Linear Programming Applications pp.121-194 in Marketing, Finance, and
Operations Management, Marketing Applications, Media Selection, Marketing Re-
search, Financial Applications, Portfolio Selection, Operations Management Applica-
tions, Production Scheduling, Workforce Assignment, Blending Problems. Formulat-
ing a linear programming model from a written problem statement is often difficult.
The steps for model formulation described in this section are generally followed; how-
ever, the problem must first be defined (i.e., a problem statement or some similar
descriptive apparatus must be developed). The objective function and model con-
straints can be very complex, requiring much time and effort to develop. Simply
making sure that all the model constraints have been identified and no important
problem restrictions have been omitted is difficult. It is not uncommon for linear pro-
gramming models of real problems to encompass hundreds of functional relationships
and decision variables. What is possible is to provide the fundamentals of linear pro-
gramming model formulation and solution prerequisite to solving linear programming

• Chapter 6. Distribution and Network Models pp.195-254, Transportation Problem,
Assignment Problem, Problem Variations, Transshipment Problem, Problem Varia-
tions, A General Linear Programming Model. In this chapter, three special types
of linear programming problems will be presented, the transportation problem, the
transshipment problem, and the assignment problem. As mentioned before they are
part of a larger class of linear programming problems, known as network flow prob-
lems. In the next chapter, we examine several additional examples of network flow
problems, including the shortest route problem, the minimal spanning tree problem,
and the maximal flow problem. Although they have different objectives, they share
the same general characteristics as the transportation and assignment problemsthat
is, the flow of items from sources to destinations.
• Chapter 7. Shortest-Route Problem pp.255-306, A General Linear Programming
Model, Minimal Spanning Tree, A Minimal Spanning Tree Algorithm. In this chapter,
we will examine a class of models referred to as network flow models. These included
the shortest route network and the minimal spanning tree network. These network
models are all concerned with the flow of an item (or items) through an arrangement
of paths (or routes). We will demonstrate solution approaches for each of the types
of network models. At times, it may have seemed tiresome to go through the various
steps of these solution methods, when the solutions could have more easily been found
by simply looking closely at the networks. However, as the sizes of networks increase,
intuitive solution by observation becomes more difficult, thus creating the need for
a solution procedure. Of course, as with the other techniques in this text, when a
network gets extremely large and complex, computerized solution becomes the best
approach.
• Chapter 8. Probability and Statistics pp.307-342. Students are advised to read this
chapter on their own.

• Chapter 9. Decision analysis pp.343-406 has been widely used in practice. The
purpose of this chapter is to demonstrate the concepts and fundamentals of decision
making when uncertainty exists. Within this context, several decision-making criteria
will be presented. The maximax, maximin, minimax regret, equal likelihood, and
Hurwicz decision criteria are demonstrated for cases in which probabilities cannot be
attached to the occurrence of outcomes. The expected value criterion will be discussed
for cases in which probabilities can be assigned to the states of nature of a decision
situation. All the decision criteria presented in this chapter are demonstrated by ex-
amples; actual decision-making situations are usually more complex. Decision analysis
can be used to determine a recommended decision alternative or an optimal decision
strategy when a decision maker is faced with an uncertain future events. The goal
of decision analysis is to identify the best decision alternative or the optimal decision
strategy given information about the uncertain events and the possible consequences
or payoffs. The uncertain future events are called chance events and the outcomes of
the chance events are called states of nature.
• Chapter 10. In this chapter pp.407-448 we present a variety of waiting line models
that can help managers make better decisions concerning the operation of waiting
lines. For each model, we will present formulas that can be used to develop operating
characteristics or performance measures for the system being studied. The operating
characteristics include the following:
– Probability that no units are in the system.
– Average number of units in the waiting line.
– Average number of units in the system.
– Average time a unit spends in the waiting line.
– Average time a unit spends in the system.
– Probability that arriving units will have to wait for service.
However, with a little creativity, waiting line models can be applied to many different
situations such as telephone calls waiting for connections, mail orders waiting for
processing, machines waiting for repairs, manufacturing jobs waiting to be processed,
and money waiting to be spent or invested.

FFFF(Chapters 2, 3, 4, 5, 6, 7, 9, 10) for the final exam.
IMPORTANT NOTE:
Students are strongly advised to go through solved examples, Problems and Case Problems
in the textbook. Always adopt pen and paper for doing Management Science problems. You
will be deceiving yourself if you simply read the text. In order to draw the maximum benefit
out of this course, you should always, before going to the next lecture, go through the reading
assignment. This will create greater interest in the lecture.
The final grade will be determined based on the scores obtained on the closed-book test,
several graded quizzes and on the final exam. On all the written tests, you have to show all
your work on the paper you hand in. The grade will be based on the work shown, not on
what was intended or implied. A correct answer is not sufficient for full credit: missing or
poorly justified steps, excessively sloppy and disorganized work will result in a lower grade.
It is the Responsibility of all Students.
• FF Responsibility: You are responsible for obtaining notes and handouts
from any classes you miss.
• FF Attendance: It has been observed that your attendance in class has a
direct correlation with your final grade. Do make an attempt to attend all
classes.
• FF Exams: The Tests and Final will be closed book, no notes allowed.
• FF Students should familiarize themselves each year with the university’s
academic regulations and policy in general;
• FF Students should familiarize themselves with the regulations and poli-
cies applying specifically to their faculty, school, or program;
• FF Students should familiarize themselves with the specific graduation
requirements of the degree, diploma, or certificate they are seeking; and
10
-
• FF To ensure that the courses they have selected are appropriate to their
programs.
Attendance Policy
Attendance will not be taken. However, students are expected to attend the classes. While
your absences will not directly influence your grades, you are responsible for all material
covered in class whether you attend classes regularly or not. Ultimately, the final grade
will depend on how much you have learned and not how often you came to class (although
the two are usually highly correlated since missing classes may impair your understanding
of the material). If you need my help and are unable to come to my office hours, don’t
hesitate to schedule an appointment to see me some other time. The best way to contact
me outside office hours is by e-mail. Feel free to interrupt me (as long as you don’t overdo
it) during class and to talk to me after class if you have questions. You are expected to be in
a professional business manner in asking questions and replying to questions from both the
instructor and other classmates. Late arrivals and walking in and out of the class disrupt
the flow of the class. Please avoid private conversations that may distract your classmates
and your instructor, and turn off your cellular phones.
You must come to my office prepared in the following sense: before posing a question,
make a serious effort to answer it yourself. In particular, if you have a question about an
exercise, make every effort to understand its formulation, the definitions and theorems that
are related to the exercise, as well as the employed notations. Most likely it will be enough
for you to read the corresponding paragraphs in your notes and/or the textbook. In short,
office hours will not be a substitute for lectures.
Exam Policy
No cellular telephones or other electronic communication devices are allowed during exam-
inations. Such items will be removed when discovered, and returned upon the completion
of the examination.
No make-up examinations will be given. If you miss a Mid-Term Examination for health
reasons you are expected to have your doctor complete a Medical Absenteeism Form and
submit it to your instructor.
If you miss the Final Examination you will be required to consult with the Student Advisors
11
-
in the Undergraduate Program Office, Room 268 Drake Centre. If you meet the criteria and
qualify for a Deferred Final Examination, the Department of Supply Chain Management
will schedule another opportunity in the New Year for you to write your Final Examination
in the course.
If you miss a Mid-Term Examination for a reason other than illness, you are expected
to contact your instructor at your earliest possible opportunity and explain the circum-
stances surrounding your absence. Your instructor will require appropriate documentary
evidence to justify your absence. Then the matter will be referred to the Department Head
to ensure that all scenarios are dealt with in a uniform manner.
ADDITIONAL RESOURCES: Your textbook contains numerous Problems, Self Test
Exercises and Case Problems (voluntary or otherwise) at the conclusion of each chapter.
You are seriously encouraged to work through many of them in order to consolidate your
understanding and provide you with confidence when writing the examinations.
You will have Library Reserve Access to Practice Mid-Term Examinations and a Practice
Final Examination. These former examinations will make you aware of the examination
format and the scope of the material included in an examination in this course. You will re-
alize that you will be expected to solve a variety of analytical problems in a limited amount
of time and space.
The best way to succeed in this course is to read your textbook, practice solving problems,
complete homework prior to each class, and review the lecture notes with the examples
done in class. It is strongly advised that you start studying for this course well before the
examination date. Few students are able to learn all the required topics in the last week
before the examination. Limited knowledge of a few of the topics covered in the class may
not be sufficient to earn a passing grade in the course.
ACADEMIC INTEGRITY:
It is critical to the reputation of the Asper School of Business and of our degrees, that
everyone associated with our faculty behave with the highest academic integrity. As the
faculty that helps create business and government leaders, we have a special obligation to
ensure that our ethical standards are beyond reproach. Any dishonesty in our academic
12
-
transactions violates this trust. The University of Manitoba General Calendar addresses
the issue of academic dishonesty under the heading Plagiarism and Cheating. We expect
you to familiarize yourself with the Academic Integrity guidelines. Students who violate
University standards of academic integrity are subject to disciplinary sanctions, including
failure in the course and suspension from the University. Since dishonesty in any form
harms the individual, other students, and the University, policies on academic integrity will
be strictly enforced.
Offenses: Cheating on any exam, quiz, work to be completed in class; theft, or attempted
theft of exam questions; possession of exam questions prior to the time for examination; or
use of a graphing calculator on a test shall all be offenses subject to appropriate penalties.
I expect you to exhibit integrity in all of your actions related to this course.
What does integrity mean? On exams, the meaning is clear: dont cheat, and
we all know what that means. In addition to homeworks, I will provide practice
midterms and a practice final. These are based on past exams and are meant
as a guide for how the exams may look like. They are not meant to tell you
what will be on the exam.
How to study for this class: We will cover a wide range of topics in this
class. The exams will require that you can solve analytical problems in a limited
amount of time. The best way to succeed in this class is to thoroughly practice
solving problems, doing the homeworks, reading the textbook, and reviewing the
lecture notes and examples given in class. I strongly advise you to start study-
ing for this class well before the exam date. Few people manage to learn all the
required topics in the last week before the exam. Limited knowledge of a few of
the covered topics may not be sufficient to pass the course.
