expectations handouts
Expectations - Handouts
  • You are expected to print and bring your handout to class.
  • Fail to have your HO repeatedly will negatively impact your grade.
  • Most real life problems cannot be solved exactly.  Numerical analysis is the study of methods that approximate solutions numerically.
population model
Population Model
  • N(t) = size of a population
  •  = birth rate
  • v = immigration per year (constant)
population model1
Population Model
  • N0 = 1,000,000, N(1) = 1,564,000
  •  = ???
  • v = 435,000
  • 2 Mid-term Exams and a Final Exam.
  • Homework problem sets will be assigned.
  • All work must be typed.
  • The ONLY references you can use are the textbooks and the lecture note.  You cannot use any other resources such as other books, software, and the internet.  
  • Group HW
  • Individual HW
group homework
Group Homework
  • You are required to work together in a group of 2 (or 3 if approved).
individual homework
Individual Homework
  • No discussion with any other person, except may be the instructor. 
  • Discussing or copying homework is considered as an act of academic dishonesty
  • Staple your Homework.  Points will be taken off if you fail to do so.
  • Homework is due at the beginning of the class. Absolutely no late homework.
  • Homework must be written with proper logical format.
  • Pay attention to the notations and format used in the lecture. You need to follow the notations and presenationof the class notes in the case that they are different from the textbook and supplemental materials.
  • *.doc Type with Equation Editor
  • *.docx Saved to.docx to type with MS Equation Editor
  • Daily Short Quizzes (5 -15 min.)
  • Cover the materials discussed in the last class session and reading assignment.
  • This is to encourage you to
    • study alone the way, instead of spending 15 straight hours the night before exam;
    • Prepare for the next class.
class participation
Class Participation:

1. There are reading assignments everyday.  I will ask questions during the class period to check your reading progress

2. There are classwork in some class sessions.

3. You are expected to print and bring the handouts.

At the end of the quarter, your grades on class participation will be determined by the above activities and other observations by the instructor.

  • You may have limited discussions with one group partner
  • Each one need to write up his/ her own solutions and Maple implementations
  • You are not learning if you constantly depends on someone else to finish you work.
  • You need to develop the ability to debug your program.
modeling contests
Modeling Contests

Each group will enter into one of the following modeling contests (2/6-2/10):

  • MCM: The Mathematical Contest in Modeling
  • ICM: The Interdisciplinary Contest in Modeling
modeling contests1
Modeling Contests
  • Case Studies are selected from past contest problems
  • Registration Fee: $100 per team
  • Part of the mid-term exam
modeling contests2
Modeling Contests
  • A “N” grade will be given at the end of the quarter.
  • Grades for the MCM will be assigned as follows
incomplete policy
Incomplete Policy
  • No incomplete will be given if you do not already have a passing grade (70%) at the time of the request.
attendance policy
Attendance Policy
  • Coming to class is extremely important.
  • You are expected to be on time.
  • You will not get a course grade higher than C- if you do not have at least 90% of attendance*.
  • You will not get a course grade higher than D if you do not have at least 80% of attendance*.
make up policies
Make-Up Policies
  • NO makeups for classworks.
make up policies1
Make-Up Policies
  • NO makeups for classworks.
  • If a student has a  documented conflict that will prevent him or her from taking an exam at the scheduled time, he/she must arrange IN ADVANCE with the instructor to take the exam early. 
make up policies2
Make-Up Policies
  • Makeups are NOT AUTOMATIC.
  • Do NOT assume that because you miss an exam that you will get to make it up. A makeup exam must be APPROVED by me. Lying to avoid taking an exam is considered as an act of academic dishonesty.
  • Talk to me. I am available during office hours and other times.
  • Computer algebraic system Maple (version 17) will be used in this course to implement numerical algorithms.  
  • Maple will be available for use on computers in labs throughout the campus. 
  • Copies of the software for use on your own computer will also be available for purchase at a substantial discount for students (Discount code: AP??????).

  • Read Zeng 1.1, 1.2
  • You need to print your handouts prior to the class time.
  • Do not use the printer in this room without the instructor’s approval.
  • Handouts will be finalized by 10 pm the night before.
2002 mcm problem b airline overbooking
2002 MCM problem BAirline Overbooking
  • You are all packed and ready to go on a trip to visit your best friend in New York City. After you check in at the ticket counter, the airline clerk announces that your flight has been overbooked. Passengers need to check in immediately to determine if they still have a seat.
2002 mcm problem b airline overbooking1
2002 MCM problem BAirline Overbooking
  • Historically, airlines know that only a certain percentage of passengers who have made reservations on a particular flight will actually take that flight.
  • Consequently, most airlines overbook—that is, they take more reservations than the capacity of the aircraft. Occasionally, more passengers will want to take bumped and thus unable to take the flight for which they had reservations.
2002 mcm problem b airline overbooking2
2002 MCM problem BAirline Overbooking
  • Airlines deal with bumped passengers in various ways. Some are given nothing, some are booked on later flights on other airlines, and some are given some kind of cash or airline ticket incentive.
2002 mcm problem b airline overbooking3
2002 MCM problem BAirline Overbooking

Consider the overbooking issue in light of the current situation:

  • fewer flights by airlines from point A to point B;
  • heightened security at and around airports,
  • passengers’ fear, and
  • loss of billions of dollars in revenue by airlines to date.
2002 mcm problem b airline overbooking4
2002 MCM problem BAirline Overbooking
  • Build a mathematical model that examines the effects that different overbooking schemes have on the revenue received by an airline company, in order to find an optimal overbooking strategy—that is, the number of people by which an airline should overbook a particular flight so that the company’s revenue is maximized.
2002 mcm problem b airline overbooking5
2002 MCM problem BAirline Overbooking
  • Ensure that your model reflects the issues above and consider alternatives for handling “bumped” passengers.
  • Additionally, write a short memorandum to the airline’s CEO summarizing your findings and analysis.
2007 mcm problem b the airplane seating problem
2007 MCM problem BThe Airplane Seating Problem
  • Airlines are free to seat passengers waiting to board an aircraft in any order whatsoever. It has become customary to seat passengers with special needs first, followed by first-class passengers (who sit at the front of the plane). Then coach and business-class passengers are seated by groups of rows, beginning with the row at the back of the plane and proceeding forward.
2007 mcm problem b the airplane seating problem1
2007 MCM problem BThe Airplane Seating Problem
  • Apart from consideration of the passengers’ wait time, from the airline’s point of view, time is money, and boarding time is best minimized. The plane makes money for the airline only when it is in motion, and long boarding times limit the number of trips that a plane can make in a day.
2007 mcm problem b the airplane seating problem2
2007 MCM problem BThe Airplane Seating Problem
  • Devise and compare procedures for boarding and deboarding planes with varying numbers of passengers: small (85–210), midsize (210–330), and large (450–800). Prepare an executive summary, not to exceed two single-spaced pages, in which you set out your conclusions to an audience of airline executives, gate agents, and flight crews.
