The INFORMS Optimization Section was formed in the fall of 1995 and became a Society in 2004.

The Optimization Society has two goals:

  1. to promote the development and application of optimization methods and software tools for the solution of problems in Operations Research/Management Science, and
  2. to encourage the exchange of information among practitioners and scholars in the optimization area.
