Detailed Description

TIM file reader - the stage information for a stochastic programming instance in SMPS format.

Author

Stephen J. Maher

This is a reader for the time file of a stochastic programming instance in SMPS format. The three files that must be read are:

• .cor
• .tim
• .sto

Alternatively, it is possible to create a .smps file with the relative path to the .cor, .tim and .sto files. A file reader is available for the .smps file.

Details regarding the SMPS file format can be found at: Birge, J. R.; Dempster, M. A.; Gassmann, H. I.; Gunn, E.; King, A. J. & Wallace, S. W. A standard input format for multiperiod stochastic linear programs IIASA, Laxenburg, Austria, WP-87-118, 1987
