As it was announced in the class yesterday, the Final
Examination for 

the course will
take place on Wednesday, August 07 from 19:00 to 22:00 

in CLH J. The exam will be comprehensive,
covering the entire course 

material according to the
Course Schedule but
with an emphasis on the 

more recent material covered
after the third test. If less common formulas 

are needed on the exam, then
those will be provided on the exam. 

There will be several questions, some with a few parts. Marks for each 

question will be indicated. You have to show all your work, and you 

should explain your solutions where appropriate. Unofficial final grades 

for the course will hopefully be posted to the course web page by 

Wednesday, August 21. Please also note that I will be holding an 

additional office hour for last minute questions on Tuesday, August 06 

from 14:00 to 15:00.

Course Description: An introductory course in Operations Research. The course deals with standard optimization techniques used in Operations Research. The main topics include: a) Linear Programming: the theory and applications of linear programming including the simplex algorithm, duality theorem, postoptimality analysis, and a discussion of the types of problems that lead to linear programming problems; b) Transportation Problems: the transportation algorithm with applications to network flows, assignment problems, shortestroute problems, and critical path scheduling; c) Integer Programming: a study of the situations leading to integerprogramming problems, branchandbound algorithm for solving such problems; d) Dynamic Programming: an introduction to the concepts of dynamic programming with a discussion of typical problems and their solutions. The emphasis will be on practical problems representative of the field of Operations Research. With the help of notes and class instructions students will be introduced to the optimization solver software LINDO/LINGO and the spreadsheet. For a more detailed list of topics with references to the textbook, please see Course Schedule.

Note: The course will not cover all the sections of the chapters of the textbook.
Throughout the term, homework problems will be posted to the Announcements Section of the course web page. In order to develop your understanding of the course material you must do all assigned problems. These will not be collected for grading and hence will not directly affect your grade. However, it is extremely important that you complete all assigned exercises. Do not memorize them. Rather, learn how to solve problems like them. Learning Mathematics is not a spectacular sport, it is a participatory event. There is nothing like a bit of computation to strengthen understanding in mathematics! Use the Solutions Manual only after you have tried the problem. Solutions to typical homework problems will be posted to the course web page. Successful students must keep up with homework and seek help for points they do not understand as soon as possible. Do not fall behind! It is recommended to read the relevant sections of the textbook before every class. Next to the classes, working out the answers to the problems is the most important preparation for the tests and exam that will contain for the most part but not exclusively, questions very similar to those from the textbook. It is quite practical to work on your own or together in small groups. Each student should do at least two hours of independent study for every lecture hour. The amount you learn in this course and the grade you receive will be proportional to the amount of time you spend working on problems.
Please turn off all cell phones, iphones,
ipods, ipads and pagers
before entering the lecture hall. For tests and exam cell phones, iphones, ipods, ipads, calculators, digital dictionaries, palms, pagers or
any other electronic devices are NOT allowed. All such devices as well as all
books, papers, knapsacks and briefcases must be left at the front of the
lecture hall. Anyone caught with electronic devices will be charged with
Academic Dishonesty (see the next page). The only items you may have at your
seat are pens, pencils, student ID and purses. You are responsible for all
material covered in lectures.
Note: Photo identification and signingin are required at all
tests and exam.
The official grades at York University are LETTER grades. Qualitative descriptions of these grades can be found in the York Calendar at this link. Your test marks will be on a numerical
scale because these have to be weighted and averaged in various ways, but THERE IS NO AUTOMATIC
PREDETERMINED CORRELATIONS BETWEEN NUMERICAL GRADES AND LETTER GRADES in this course. In particular, the
"numerical" grades you
receive are NOT to be interpreted as percentages; they are merely 'raw scores'. Once the tests are returned in class, the distribution
of 'raw scores' will be announced along with their approximate
conversion to letter grades. The median
letter grade for the course will
likely fall between C and C+.
The composition of the final grade is as follows:
Three classtests (75 minutes each, written tests held in lecture
periods): 20% each, of the overall grade (Tentative dates for the tests:
Wednesdays, May 29, June 26 and July 24, 2013).
Final examination (3hour exam scheduled by the Registar's
Office): 40% of the overall grade will take place during the examination
period between August 06 and 16, 2013.
Note: Students have five days from the date of the return of test
papers to appeal their marks. Some test papers (randomly selected) are
photocopied before they are handed back, so we can detect subsequent
alterations. Once you have written all three tests and your final exam
grade is higher than your average test grade, your final exam will be counted
as 60% and term grade as 40% of your overall grade for the course.
Makeup Policy:
No permission will be given to a student to write the
tests in advance of their scheduled dates. No makeups will be done for the
tests. A missed test will be counted as zero, except under extreme
circumstances in which case the corresponding percentage of the overall grade
will be "forwarded" to the final exam. If you miss a test for medical
reasons, you must turn in within one week following the test date the Attending
Physician's Statement form provided here after getting it filled in by your doctor. No
other type of medical note will be accepted. However, missing tests is
extremely dangerous and not recommended. As experience has shown, students who
miss class tests because of some 'mysterious illnesses' will usually average
30% on the final exam. A student who misses the final examination will be
allowed to write a makeup exam only if both of the following conditions are
met:
1) the student notifies me (raguimov@mathstat.yorku.ca)
or the Department of Mathematics and Statistics (Undergraduate Office, N502/503
Ross Building, 4167362100 4167362100, Ext. 55902 or 33969) in advance that
the exam will be missed,
2) the student submits within one week following the exam date the Attending
Physician's Statement form provided here after getting it filled in by his/her doctor.
Students who miss the final examination and do not meet both conditions will
receive a grade of F. It is student's responsibility to fill out and submit the
Deferred Standing Agreement Form.
Note: Do not make vacation/job plan until the final exam date is
known: having a plane ticket for Banff or Hawaii on August 10 is NOT a
legitimate excuse for absence from a final examination on August 15.
Religious Observance:
York University is committed to respecting the religious beliefs and practices of all members of the community and making accommodations for observances of special significance to adherents. If any of the dates specified in the course schedule for the tests pose such a conflict, students should contact me (raguimov@mathstat.yorku.ca) within the first two weeks of classes. Please note that if the final exam date poses a conflict, students must complete the Examination Accommodation Form, which can be obtained from the Registrar’s Office.
Academic Honesty:
Students are responsible for familiarizing themselves with University Policies and Regulations. Conduct that violates the ethical or legal standards of the university community or of one’s programme or specialization may result in serious consequences. Refer to the Senate Policy on Academic Honesty.
Individual questions can be discussed by email or in person after class, or during office hours. Please send all email notes as plain text within the body of the message. Do not send attachments or HTMLformatted mail. Also, if the name of your account is an alias, I will not know who the mail is from unless you sign it; it also risks being accidentally discarded as junk mail. The course web page will be updated regularly to include important announcements made in class, such as the material to be covered on the tests. Email notes requesting such information contained on the web page will be answered the last.
