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
Americans with Disabilities Act: If you have a physical, psychological, medical or learning disability that may impact your course work, please contact Disability Support Services, ECC(Educational Communications Center) Building, Room 128, (631)632-6748. They will determine with you what accommodations, if any, are necessary and appropriate. All information and documentation is confidential.
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).
