IEOR 4000 Production Management

Fall 05

Last Updated: 9 /12/05

Prerequisites: Calculus, deterministic models, probability and statistics. Deterministic models can be taken concurrently.

Description: Inventory control with known demands, multiple products, joint replenishment problem, economic lot scheduling problem, production planning with time-varying demand with economies and diseconomies of scale. Aggregate production planning, material requirement planning, forecasting, inventory control with random demands: style goods, base stock policies, (Q,r) and (s,S) policies. Multi-stage stochastic inventory models in series, assembly and distribution.

Grading: Assignments (15%), Midterms (40% each), and Final (45%). Midterm and Final exams are closed text and closed notes. You can bring one (1) one-sided 8.5" by 11" sheet with formulas and a calculator to the exams. All examinations and written homework are subject to the usual standards of academic honesty as described in the University's Student Handbook. There will be assigned readings to be done before class. Solutions to most of the assignments are available for download below. The solutions are available to facilitate the learning process. Students should try to solve all the problems before looking at the solutions. Students should submit complete assignments to receive full credit. There is no specific due date for the assignments, but it is a good idea to send in complete assignments to CVN within two weeks of the time the material is covered in class.

Sample Midterm exam: Students are allowed one single sided sheet of notes and a calculator: (pdf file) solution (pdf file).  

Final exam: TBA

Software requirements: Recent versions of Microsoft Excel. Access to Crystal Ball or @Risk is desirable but not essential.

Hardware requirements: Access to Pentium based or equivalent PC
