Advanced Operations Research: Stochastic Programming

Course content

This course introduces the students to optimization under uncertainty by means of stochastic programming. In many real-life problems input data is often uncertain, noisy, imprecise. For these problems, the course illustrates different problem formulations, discusses how uncertain parameters can be transfortmed into "scenarios", discusses specific properties of stochastic programs, and shows how to exploit these properties in various solution methods. Furthermore, the students of this course will independently handle practical problems in project work. The content can be summarized as follows.

A. Stochastic programming problems:

  • A1. Formulations of stochastic programming problems.
  • A2. Examples.
  • A3. Implementation and solution of mathematical programming problems using state-of-the-art optimization software (e.g., GAMS, AMPL, Cplex or the like).
  • A4. Analysis of the solution.

 

B. Scenario generation:

  • B1. Moment matching.
  • B2. Sampling.
  • B3. Scenario tree construction.
  • B4. The quality of scenario generation methods.

 

C. Properties of stochastic programming problems:

  • C1. The value of stochastic programming: EVPI and EEV.
  • C2. Structural properties of stochastic programs.

 

D. Solution methods:

  • D1. L-shaped decomposition.
  • D2. Integer L-shaped decomposition.
  • D3. Dual decomposition.

 

E. Practical aspects and applications:

  • E1. Implementation of a real-life problem using optimization software.
  • E2. Implementation of a solution method using optimization software.
  • E3. Case studies from e.g., Energy planning, Finance, Transportation.
