The models that I am trying to develop and run have a lot of indexes from 3 to 6 sets, or more. Forest Management models have thousands of variables and constraints. It is multiperiod model from 1 to 100 year time period. It is even hard to interpret the result in glance without creating graphs. The constraints are non-declining yield, no death in the plantation, etc. The results needs to be formatted in various forms for the graphs and output as csv files. I have to run the model several times to get a realistic outcome. I am trying to mimic this software - Spatial Woodstock http://www.remsoft.com/forestrySoftware.php One features of this software are: * easy to model - themes - set or indexes, I have developed a model with 10 indexes using this software * read dbf file or shapefiles for the area (I have done this in MathProg already) * creates interactive graphs for easy interpretation of the run. * expensive - > $25, 0000 for suite initial license - Not my liking :-). Company pays for this license. The woodstock model runs in minutes to 1 hour depending on the size of the model. I have not yet replicated my woodstock model to GLPK/MathProg yet. Graphing in Excel is not option while running this big model. Takes a lot of time to do the graphs in Excel. I am trying to configure GUSEK to run GNU Plot. I started tweaking / creating gnuplot.properties for GUSEK and learning GNU Plot. I asked Luis for help and sent a copy of the draft gnuplot.properties. I think GUSEK can run GNU Plot Noli > I think one of the glpk examples demonstrates generaring gnuplot commands as > it output. _______________________________________________ Help-glpk mailing list [email protected] http://lists.gnu.org/mailman/listinfo/help-glpk
