Course Text: Operations Research , by Wayne L. Winston, 4th edition.
Tests: one mid-term and a (non-cumulative) final. The final is Friday,
Dec. 19th, 11:15am-1:45pm in regular classroom. Tests will be closed book
but a one-page sheet of notes will be permitted for the final. The mid-term counts 35% of the grade and the final 50% of the grade.
Homework: There will be 9 homework assignments, due approximately weekly. They will count about 15% of the grade.
Homework will be submitted through Blackboard and graded with scores of 5,4,3,2,1,0.
Software: LP's can be solved by many software programs. The textbook
uses Lindo and you can download 'classic' Lindo free at www.lindo.com

psychological, medical or learning disability that may impact your
course work, please contact Disability Support Services,

any, are necessary and appropriate. All information and documentation
Academic Integrity: Each student must pursue his or her academic
goals honestly and be personally accountable for all submitted work.
Representing another person's work as your own is always wrong.
Faculty is required to report any suspected instances of academic
dishonesty to the Academic Judiciary. Faculty in the Health Sciences
Center (School of Health Technology & Management, Nursing, Social
Welfare, Dental Medicine) and School of Medicine are required to
follow their school-specific procedures. For more comprehensive
information on academic integrity, including categories of academic
dishonesty please refer to the academic judiciary website at
Critical Incident Management: Stony Brook University expects students
to respect the rights, privileges, and property of other people.
Faculty are required to report to the Office of University Community
Standards any disruptive behavior that interrupts their ability to
teach, compromises the safety of the learning environment, or
inhibits students' ability to learn.
COURSE OUTLINE: The following topics will be covered: (Background
recommended reading Chapters 1-2), LP formulations (Chapter 3), The Simplex
method (Chapter 4), Sensitivity analysis (Chapter 5 Sections
1-3) Duality, (Chapter 6, Sections 4-8), Transportation and Assignment problems
(Chapter 7 Sections 1-3, 5), Integer programming (Chapter 9 Sections 1-4, 8)
and Dynamic Programming (Chapter 13, Sections 1-2, 4-5).
1.Become familiar with the many optimization problems arising in diverse settings that can modeled as linear programs, and
gain experience in constructing mathematical models for an array of such optimization problems.
* Maximizing income subject to supply constraints;
* Minimizing costs subject to minimum requirements;
* Scheduling problems;
* short-term and long-term financial planning problems;
* blending problems;
* multi-period planning problems.
2.Learn to solve linear programs geometrically and with the simplex algorithm.
* putting linear programs in standard form with slack and excess variables;
* finding an initial basic feasible solution (using big M or two-phase simplex for min problems);
* choosing which variable enters and which variable leaves the basis;
* handling unbounded and infeasible problems.
3.Understand sensitivity analysis and its connection with the theory of dual linear programs.
* shadow prices and reduced costs;
* range for objective function coefficients and right-hand sides;
* connections to the dual linear programs and complementary slackness.
4.Learn specialized algorithms for solving network problems, such as transportation problems and critical path problems.
* traansportation problem;
* assignment problems;
* critical path problem.
5.Model discrete optimization problems with integer programs and solve using a branch-and-bound strategy.
* model various discrete optimization problems as integer programs;
* solve integer problems using a branch-and-bound strategy.
6.Solve simple dynamic programming problems.
* model a class of discrete optimization problems as dynamic programs;
* solve simple dynamic programs using a squential solution technique
