Operations Management (33:623:386) -- Spring 2010, Professor Eckstein

Study Guide for Midterm 2

The exam will cover material from the classes of February 23 (class 11) through
April 1 (Class 20). Material from the classes of April 6 and 8 (classes
21-22) may be covered on
the final exam, but not on this midterm. Regarding the exam format:

- There will be one algebra question about integer programming modeling.
- There will one spreadsheet question on simulation (YASAI) modeling
- There will
*not* be a spreadsheet question about using Solver on this
midterm.

You should study the following material:

- Examples covered in class and/or class notes from February 23 through
April 1. This material includes:
- Integer programming
- Binary and general integer variables
- Assignment problems and "grids" of binary variables
- Set covering constraints
- Set partitioning constraints
- Logic constraints (this or that, if this then than, etc.)
- "Fixed charge" models: modeling setup costs and related disjunctions

- Basic simulation modeling with YASAI and discrete (whole-number) random
variables
- Empirical probability distributions (GENTABLE)
- Independence, binomial distributions
- Poisson distributions, and when they should be used
- Simple continuous distributions: normal and uniform
- PARAMETER function in YASAI, including testing multiple parameters
- When to use SIMOUTPUT

- Homework assignments 6-9, including the solutions
available on Sakai
- Solutions to assignments 1-7 are already posted. The solution to
assignments 8 and 9 will be posted before the exam.

- Practice problems from the back of the coursepack (solutions to
all the practice problems may be found in the coursepack immediately after the
problems; if you have an older edition of the coursepack, add 3 to each page
number below):
- Choosing a class schedule, p. 261
- Hiring consultants, p. 264
- Producing trucks, part (d) only, pp. 264-265
- Fruit of the month, pp. 265-266
- Online auction, p. 269
- Selling dresses, p. 275
- Semiconductor fabrication, p. 277
- Miniature locomotives, pp. 278-279
- Staffing an office, pp. 280-281
- Chickens and eggs, pp. 282-283

The following are actually *final* exam practice problems, but similar
to questions you might encounter on this midterm
- Bouquets, pp. 312-313
- Preparing reports, pp. 327-328
