Introduction

Nichalin S. Summerfield

  • Ph.D. Candidate in Management (Operations Management), Expected December 2010.

  • Dissertation Title: Games of Decentralized Inventory Management

  • Dissertation Advisor: Dr. Moshe Dror

  • Minor: Economics

    Research Interests:

  • Game Theory (Cooperative and Non-cooperative Game)

  • Operations Management (Supply chain and inventory management)


Games of Decentralized Inventory Management


The 1st chapter: Prelim exam paper

Influential paper:

  • Anupindi, R., Y. Bassok, E. Zemel. 2001. “A general framework for the study of decentralized distribution systems,” Manufacturing Service Oper. Management 4(3) 349-368.

    • Cited: 125 times as of today according to Google Scholar

    • This paper proposes a profit sharing mechanism that is fair if all retailers are rational and play Nash equilibrium strategy.

    • Problems: Is there a unique Nash equilibrium? Will retailers always play Nash?

      My prelim exam paper answered these problems.

  • Suakkaphong, N. and Dror, M. (2010) “Managing Decentralized Inventory and Transshipment,” TOP – Journal of the Spanish Society of Statistics and Operations Research, (in press).


The 2nd chapter: Oral exam paper

  • The setting as described in Anupindi et al. (2001) is too restricted. A minor change in the setting can change the game, the model and the result.

  • Problems: What are the settings that have been studied? Is there a general framework that can be used?

    My oral exam paper addresses these.

    • Suakkaphong, N. and Dror, M. (2010) “Stochastic Programming Framework for Decentralized Inventory with Transshipment,” (In revision)


Taxonomy of Decentralized Inventory Games with Transshipment

The 3rd paper

Prelim exam paper


The 3rd chapter: In progress

  • Suakkaphong, N. and Dror, M. (2010) “Biform Game: Reflection as a Stochastic Programming Problem,” (in progress)

    • Expands beyond decentralized inventory games

    • Based on another influential paper

      • Brandenburger, A., H. W. Stuart Jr. 2007. “Biform games,” Management Science 53(4) 537-549.


Q & A

  • Developing each work

    • Discuss with my advisor to get an idea

    • Read a lot of papers

    • Pose a lot of questions and try to answer them myself

      • Most required mathematical modeling and numerical examples.

    • Write them down

  • What resources did you need and how did you get them?

    • Books from library

    • Journal papers from Google Scholar (MS, OR, MSOM, etc.)

    • Software: Latex

    • Talk to experts: Dr. Moshe Dror (MIS), Dr. Guzin Bayraksan (SIE), and Dr. Rabah Amir (Economics)
