Course Description

Provide motivation and introduction to equilibrium models involving economics and engineering. We will concentrate on models involving markets (Nash-Cournot, etc.), those wherein the activities are spatially diverse, and those involving energy activities or traffic flow. Areas that will be covered include:

  • Review of relevant optimization theory
  • Module 1:
    -Presentation of the mixed complementarity problem (MCP) and variational inequality problem (VIP) formats to solve equilibrium problems as well as introduction to existence and uniqueness results
    - Review of relevant game theory notions
    - Presentation of specific models for market, spatial, energy, and traffic equilibrium problems
    - Presentations for algorithms to solve these equilibrium problems
  • Module 2:
    - Presentation of mixed integer nonlinear programming (MINLP) problems in engineering
    -Two-level optimization problems (mathematical programs with equilibrium constraints) as a special case
    -More general MINLP
    -Algorithms to solve MINLP

Course Objectives:

  • Provide understanding for studying problems that involve equilibrium concepts or MINLPs in settings that involve engineering and economics
  • Learn about various equilibrium/MINLP formulations relevant to engineering and economic settings
  • Present theory for solutions to such problems
  • Present algorithms to solve these problems

Grading is based on comprehension and mastery of the material.

  • Major topic homeworks (1/3 of course grade)
  • Take-home exam #1 (1/3 of course grade)
  • Take-home exam #2 (1/3 of course grade)

Course Policies:

Students are encouraged to attend all lectures since the take-home exam and the homeworks will be closely related to material discussed in lectures. In addition, class participation is taken into account as part of the homework grade.

It is assumed that students will complete the homeworks and exams by themselves.

The University of Maryland, College Park has a nationally recognized Code of Academic Integrity, administered by the Student Honor Council. The course is subject to this Code of Academic Integrity which sets standards for academic integrity at Maryland for all
undergraduate and graduate students. As a student you are responsible for upholding these standards for this course. It is very important for you to be aware of the consequences of cheating, fabrication, facilitation, and plagiarism.  For more information on the Code of Academic Integrity or the Student Honor Council, please visit the website.

The University has a legal obligation to provide appropriate accommodations for students with disabilities. Please inform Dr. Gabriel of any accommodations needed relative to disabilities. Also, University of Maryland policy states that students should not be penalized due to observances of their religious beliefs. Please inform Dr. Gabriel of such instances well in advance so that appropriate steps can be taken.
