OR/MS Today - LINEAR PROGRAMMING SOFTWARE SURVEY

OR/MS Today

2007 LINEAR PROGRAMMING
SOFTWARE SURVEY

The information in this survey was provided by the vendors in response to a questionnaire developed by Robert Fourer. The survey should not be considered as comprehensive, but rather as a representation of available Linear Programming packages.

Questionnaires were sent to vendors drawn from previous survey participants, the OR/MS Today database and other sources. It includes the products of those vendors who responded by the deadline. If you know of a Linear Programming package that is not in this survey, please contact Patton McGinley at (770) 431-0867, ext. 214 or e-mail them to patton@lionhrtpub.com (please include vendor contact information). They will be included in the online version.

The survey is broken down into twelve separate tables (plus a vendor contact list) for easier downloading and viewing:
