Some experience using Excel, VBA, Mathematica, Maple, or Matlab will also be VERY helpful, but it is not strictly a prerequisite.

Follow-up courses: Math 325 Differential Equations, Math 418 Modeling with Linear Algebra, Math 419 Advanced Math Modeling (stochastics), Math 425 Math for Scientists, Math 436 Numerical Analysis

The U of M has two related courses: Math 462, "Mathematical Modeling", and Math 463, "Mathematical Modeling in Biology". However, these focus on differential equation models, while this class focuses on regression, operations research, and dynamical systems.

"Final Exam" schedule: Tue, Aug. 17th, usual class time

CRN 41956, 3 credit hours.

Class meetings will be mostly interactive lectures, with some time to work on problems in class, and some time to discuss homework.

Math department main office: Hoyt 404, (734) 487-1444

- M/T/R 9:30am-10:30am (location TBA)
- M/T/R 12:20-1:00pm (starting at Roosevelt 101, walking to MarkJ 122, eating lunch on the way)
- M/T/R 3:00-4:00pm (location TBA)

I am also happy to make appointments if you cannot come to the general office hours. Please send me e-mail to arrange an appointment.

I am definitely unavailable during the times I teach other classes:- M/T/R 10:30am-12:20pm

The Mathematics Student Services Center (or "Math Lab") is also here to help you, in 117A King Hall. Their hours are posted here. Please give them a call at 734-487-0983 or just drop by.

Many assignments in this course will be in the form of papers, which I want to be well written. Please consult with The Writing Center for help in tuning up your writing.

Most students do well in this course without a textbook. For those who feel the need to have one just in case, I suggest "A First Course in Mathematical Modeling", 3rd or 4th Edition, by Giordano, Weir, and Fox.

A lot of our work will be done on computers, specifically in Excel. If you had been waiting for a good reason to buy a laptop, this is it.

I will post data files, homework assignment files, etc. on my home page.

We will use an on-line gradebook (perhaps the WebCT system) to keep track of grades. You are expected to keep an eye on your scores using the system, and get extra help if your scores indicate the need.

Our primary goal is to teach you to be a good (or great!) math modeler. To be a good modeler, you need:

- Good habits and procedures, just like a scientist, and
- Knowledge of common math models.

- Get enough people together to form a few teams for the Math Contest in Modeling (MCM), mid-February, 2011. I participated in this 3 times as an undergrad and had a lot of fun. Recent EMU teams have done well!
- Give future teachers some great ideas to show your kids how high-power math is used in the real world. You may enjoy reading Meaningful Math.
- Give computer-science students lots of interesting things to program. You may like reading this blog entry about math for programmers.
- Get everyone using Mathematica, Maple, or Matlab/SciLab.
- Teach you how to communicate your math models by writing math papers and giving math presentations.

- (General modeling skills):
- categorize problems into operational/tactical/strategic categories,
- identify nearby problems in the oper./tact./strat. hierarchy,
- evaluate models by constructing simple test cases,
- conduct cross-validation when needed,
- select the most important variables to start modeling with,

- (Empirical modeling skills):
- use ordinary, semilog, and loglog plots to evaluate relationships in data sets,
- perform linear regression in software,
- interpret the correlation coefficient,
- perform transformations before regression as appropriate,
- fit a function to data using nonlinear regression, e.g. sine waves
- decide when to use logistic regression (logit), and interpret the results

- (Communication skills):
- write a technical report,
- differentiate between literature of varying quality, e.g. peer-reviewed vs. working paper vs. white paper vs. web site,
- design appropriate figures to communicate models and results,

- (Optimization skills):
- Formulate non-linear programs (NLP) as appropriate,
- solve NLP using software,
- describe the (im)possibility of multiple optimal solutions (convexity/concavity)
- formulate linear programs (LP) as appropriate,

- describe the nature of LP solutions,
- identify common LP models: network flow, diet/blending, inventory, minimax, assignment,
- formulate Integer programs (IP) as appropriate,
- identify common IP models: knapsack, fixed charge, scheduling

- (Dynamical Systems skills):
- use Dynamical Systems to model populations:
- single-variable, incl. financial models,
- two-population: predator/prey, competition, cooperation
- age-structured populations (Leslie models)
- Markov-chain models

- Fit model parameters to data,
- Describe equilibrium behavior,
- Implement and interpret trajectory plots, phase-plane plots, and delta-a_n versus a_n plots

- use Dynamical Systems to model populations:
- (Other models):
- describe basic Queueing models,
- describe the Traveling Salesperson problem (TSP)
- describe project-scheduling models (PERT)
- describe dynamic-programming models (DP)

Here we show which chapters from the book we will probably cover, in roughly the order we will cover them. A star (*) denotes full coverage, a plus (+) denotes partial coverage, and no symbol denotes no coverage. For example, DTMCs (as cool as they are) will be covered in Math 419 rather than 319.

Ch 2:+ proportionality, similarity Ch 3:* model fitting, least-squares Ch 4:+ experimental modeling, high-order polynom, low-order polynom, splines Ch 5:+ simulation Ch 6: Discrete Time Markov Chains (DTMCs) Ch 8:+ modeling using graph theory Ch 7:+ Linear Programming (LP), one-dim. line search (and add Integer Programming?) Ch 13:* Non-Linear Programming (NLP), inventory Ch 9:+ dimensional analysis and similitude Ch 10: graphs of functions as models Ch 1:* difference equations, dynamical systems Ch 11:+ one-dim ODEs Ch 12:+ systems of ODEsSome variations in this outline are to be expected.

Regular attendance is strongly recommended. There will be material presented in class that is not in the textbook, yet will be very useful. Similarly, there are things in the textbook that are might not be covered in class, but are still very useful. If you must miss a class, arrange to get a copy of the notes from someone, and arrange for someone to ask your questions for you.

My lectures and discussions mostly use the chalkboard, along with demonstrations in Excel and other mathematical software. I do not usually have PowerPoint-like presentations, and thus cannot hand out copies of slides.

Homework will be assigned about once every week. It will sometimes be a small problem set designed to help you understand the behavior of math models. Other times, it will involve writing up a little paper on an assigned topic. All homework should be typed.

Homework papers should be submitted on-line, where they might be checked by TurnItIn.com or a similar service. This is partly to help keep you honest, and partly to help you learn acceptable ways to cite the work of others. A side benefit is that sometimes TurnItIn finds papers relevant to your work that you would not have found otherwise!

There will be no exams, unless the class demonstrates an unwillingness to be motivated any other way.

Instead of a mid-term and a final exam, you will do a mid-term and a final project. Your results will be reported in a paper and a presentation to the class. You may work by yourself or in a team of 2 people, but no groups larger than 2 will be allowed. You may switch project partners at your will. Your project grades will each be split something like this:

- 10 pct: proposal
- 80 pct: work and written report
- 10 pct: presentation

On average, students should spend a total of about 30 minutes in office hours discussing the project. Plan for this in advance!

No scores will be dropped, unless a valid medical excuse with evidence is given. In the unfortunate event of a medical need, the appropriate grade or grades will be dropped entirely, rather than giving a make-up. You are highly encouraged to still complete the relevant assignments and consult with me during office hours to ensure you know the material.

Your final score will be computed as follows:- 50 percent for all the homework together,
- 20 percent for the mid-term project, and
- 30 percent for the final project.

- 92.0 and above : A
- 88.0 to 92.0: A-
- 84.0 to 88.0: B+
- 80.0 to 84.0: B
- 76.0 to 80.0: B-
- 72.0 to 76.0: C+, etc.

- * work in groups * start the first day assignment is given * don't take too many credits w/ this class * ask a lot of questions * utilize Dr. Ross
- Do go to his office hours more than you normally would; if you have a question ask don't wait.
- See Prof. Ross in office hours and don't be afraid to email him. He is usually very helpful and approachable.
- Plan on visiting Prof. Ross during office hours in order to do well in the class. You will learn a lot in the end, but be ready to work.
- [prof ross:] add a note to the syllabus stating something to the effect of, "This class will not be like other math classes. Instead of straight-up problems or proofs, the biggest amount of work will be setting up the models, exercises, etc. and in analysing what your results mean. It will not be the mathematical work done to obtain the results that is the tricky part." But word the note better.
- attend the office hours Prof Ross is really good at explaining & helping out with the homework
- WORK TOGETHER!
- Take notes during the computer lab days and send yourself the excel sheets.
- Go to class. The computer lab days help even if you know excel well.
- Go to class. Go to office hours and pick project that you're energized about and interested in even if they're harder. It will make this math class the best one you've ever taken.
- Don't drop the class! It sounds impossible in the beginning, but stick with it.
- Don't procrastinate.
- Take differential equations close to this class, it will make more sense!
- Start projects ASAP.
- Ask questions!!! The professor will guide you along the way like Yoda.
- Talking to anyone about your projects or the homework, be it Prof. Ross or other students, is a really, really good idea.
- Never be afraid to ask for help.
- If project falls through, have backups.

I support students' right to observe religious holidays without penalty. To the best of my ability, I will schedule exams to not conflict with major religions' holidays. Students are to provide advance notice to the instructor in order to make up work, including examinations that they miss as a result of their absence from class due to observance of religious holidays. If satisfactory arrangements cannot be made, the student may appeal to the head of the department.

Academic dishonesty, including all forms of cheating and/or plagiarism, will not be tolerated in this class. Penalties for an act of academic dishonesty may range from receiving a failing grade for a particular assignment to receiving a failing grade for the entire course. In addition, you may be referred to the Office of Student Judicial Services for discipline that can result in either a suspension or permanent dismissal. The Student Conduct Code contains detailed definitions of what constitutes academic dishonesty, but if you are not sure about whether something you’re doing would be considered academic dishonesty, consult with the instructor.

Students are expected to abide by the Student Conduct Code and assist in creating an environment that is conducive to learning and protects the rights of all members of the University community. Incivility and disruptive behavior will not be tolerated and may result in a request to leave class and referral to the Office of Student Judicial Services (SJS) for discipline. Examples of inappropriate classroom conduct include repeatedly arriving late to class, using a cellular telephone, or talking while others are speaking. You may access the Code online at www.emich.edu/sjs.

If you wish to be accommodated for your disability, EMU Board of Regents policy #8.3 requires that you first register with the Access Services Office (ASO) in room 203 King Hall. You may contact ASO by telephone at (734) 487-2470. Students with disabilities are encouraged to register with ASO promptly as you will only be accommodated from the date you register with them forward. No retroactive accommodations are possible.
