SOFTWARE PROJECTS

TYPE OF PROJECT

VUMA 2008

VUMA-network 3.3

VUMA-network 3.3 is a significant upgrade to version 3.0. This version includes improvement to the reporter facility, full Vista compliancy, updated look and feel, better program stability, updated help files and refinements to the solver routines.

VUMA 2006

VUMA-network 3.0

Major upgrade from Version 2.5 especially in 2-D and 3-D graphics which allows rapid navigating and viewing of the network. Visualization of the results uses colour coded display and users are now able to customise the min-max display range to focus on specific results. The new version will be introduced to the market in mid 2006.

VUMA 2005

VUMA-network 2.5

Significant improvements over Version 2.0 are in the areas of interface graphics, solver routines, reporting, stability and changes to the data structure. The new version will be introduced to the market in mid 2005.
