B.  OTHER TEACHING ACTIVITIES

 

Curriculum development

1.      ISYE 8900 – Graduate Seminar in Combinatorial Auctions: This course is co-developed by P. Keskinocak, O. Ergun, and J. Sokol in 2002 with the goals of exploring the new and exciting area of combinatorial auctions and improving the presentation skills of the participants. Focusing on advanced and up-to-date topics of interest to Ph.D. students, the course exposes students to subjects that might otherwise not be covered in their courses, and helps them acquire expertise in certain areas of combinatorial auctions. It challenges the students to dispute and deal with advanced material, typically based on original literature from the forefront of current research, and helps them develop and strengthen their skills of reading and understanding original scientific articles.

2.      ISYE 6230 – Economic Decision Analysis: This course focuses on the interactions between multiple players (decision makers), such as suppliers, manufacturers, retailers, consumers, etc., and the resulting dynamics in a market environment. In particular, it focuses on the strategic behavior of the players in the market, the impact of the market (or contract) structure on the participants' actions and the overall market dynamics. P. Keskinocak taught the course in Spring 2003 and 2004 (both video taped for distance learning), by partly redesigning and adding new content to it. She also developed an extensive set of lecture notes and presentation slides. This course is now included in the required course list of the Economic Decision Analysis track.

3.      ISYE 8813 – Public Applications of OR/MS: This course focuses on the applications of Operations Research/Management Science (OR/MS) with public impact, in particular, in non-profit organizations. Course topics include humanitarian logistics, pre-positioning (preparedness) for humanitarian response, immunization scheduling, vaccine procurement, preparedness (food and vaccination plan) for pandemic response, and infection control at hospitals. Students participating in this course worked on real-world projects with non-profit organizations.

4.      ISYE 8803 – Health and Humanitarian Applications of OR/MS: Similar to ISYE8813, this course focuses on the applications of OR/MS with health and humanitarian impact. Course topics include patient flow optimization, evaluating the cost effectiveness of methane from landfills as a source of renewable energy, modeling the spread of measles and evaluating the effectiveness of different vaccination strategies, and prepositioning supplies for emergency response. Students participating in this course worked on real-world projects with government or non-profit organizations including CDC, Children’s Healthcare of Atlanta, Magee Women’s Hospital, University of Pittsburgh Medical Center, and Heart to Heart International.

 

Teaching materials

1.      P. Keskinocak and S. Tayur, “Managing Operations in the Time-shared Jet Business,” teaching case. (This case was the winner of the 2000 INFORMS Best Teaching Case Award).

Among important decisions for time-shared jet companies are 1) deciding on the size and the mix of the fleet and the crew, and 2) routing/scheduling of the jets to meet the service requirements while minimizing costs. This case focuses on the day-to-day operational activity of routing/scheduling and briefly touches upon the strategic decisions on fleet and crew size and mix. It has been successfully used at several universities in graduate and undergraduate courses in computer science, industrial engineering and business administration, including CS 635-Tools and Environments for Optimization (Fall 1998, Fall 2002, University of Wisconsin-Madison), Modeling for Management Science Applications (Summer 1998, 1999, Carnegie Mellon University), 45-865 Sequencing and Scheduling (Spring 2000, Carnegie Mellon University), 46-766 Supply Chain Management (Fall 1999, Carnegie Mellon University), MGTSC 467 Analytical Techniques for Management Consulting (Fall 2003, University of Alberta, Canada) and ISYE 4231-Engineering Optimization (Spring 2001, Georgia Institute of Technology).

2.      W. Elmaghraby and P. Keskinocak, “Technology for Transportation Bidding at the Home Depot,” teaching case. (This case was a finalist for the 2002 INFORMS Best Teaching Case Award)

This case is based on The Home Depot's Internet-based application of combinatorial bidding in selecting carriers for its transportation needs. It discusses bidding and bid selection issues, and the challenges faced in implementing a mechanism that addresses various technological issues and the need for educating the bidders. The case has been used in several classes at a number of universities, including ISYE 8800-The Economics of E-Commerce (Fall 2000, Georgia Tech), ISYE 6230-Economic Decision Analysis (Fall 2001, Georgia Tech), E-Commerce (Fall 2000) and Information Technology (Spring 2001) in Georgia Tech’s Executive Masters for International Logistics (EMIL) program, OIM 640-Transportation and Business Logistics (Spring 2002, University of Wisconsin-Madison), MGMT 298D: E-Business and Supply Chains (Fall 2000, University of California-Los Angeles).

3.      F. Erhun and P. Keskinocak, “Game Theory in Business Applications,” lecture notes.

With an emphasis on the applications of game-theoretic concepts in practice, these lecture notes discuss the difference between game theory and decision analysis, provide the basic building blocks of a game, followed by static and dynamic games of complete information, discuss the application of  complete information games to general market settings and supply chains, games of incomplete information and their applications within the principal-agent framework. The notes have been used in MS&E 365-Game Theoretic Models in Operations Management (Fall 2003, Stanford University) and ISYE 6230-Economic Decision Analysis (Spring 2004, Georgia Tech).

4.      M. Drake, O. Ergun, G. Karakus, P. Kerl, P. Keskinocak, J. Swann, M. Villarreal, “Humanitarian Response Planning at the Home Depot,” teaching case (in progress).

5.      O. Ergun, J. Heier, P. Keskinocak, J. Swann, “Planning for Hurricanes at Waffle House,” teaching case (in progress).

6.      P. Keskinocak, S. Xia, “Interactive Supply Chain Game,” classroom game (in progress). The primary goal of this game is to investigate the interplay between the supplier’s inventory allocation mechanism and the customers’ demand forecast and orders, i.e., to determine how customers revise their forecasts and orders in response to the supplier’s allocation mechanism.

7.      O. Ergun, G. Karakus, P. Keskinocak, J. Swann, M. Villarreal. “Big Depot Hurricane Planning,” classroom game (in progress). This game provides a synthesis between contracting and allocating inventory under demand uncertainty. It has a table-top structure, starting with general information about the supply chain setting, conditions and operations; then, every step begins with some data and information that should be used to make decisions about expected issues in the exercises. Players assume roles, which may well affect their incentives and priorities, and therefore the decisions they make.
