The purpose of this site is to introduce the user to the
functionality offered by the VEDA environment to interact with the input and
output of TIMES models. Prior knowledge of modeling in general, and TIMES
modeling in particular, is necessary to actually build models using this site. Overview of the VEDA system for TIMES modeling>
Data and assumptions are fed into VEDA_FE that
provides input to the TIMES code. VEDA_FE accepts input from a variety of
Excel files with different (flexible) structures that are tailored to work
efficiently with data intensive models. The TIMES code works in the GAMS
environment and produces text output that is read by VEDA_BE. VEDA_BE produces
numerical and graphical (mainly via Excel) output for the user. Future updates
will have VEDA_FE and VEDA_BE interacting more and more. For example, it will
be possible to view the results for the processes/commodities being browsed
in VEDA_FE. Similarly, input information for the processes/commodities
selected in VEDA_BE will be a click away. Some sections include flash animations of VEDA
operation. These are available in two ways: from the “Show me”
links, and from pictures with a red border and shadow around them. If you want
local copies of the flash demos, you can use the “Download” links
beside the “Show me”. You have (limited) control on the animation
(go to the first frame, pause, next frame and previous frame) using the
controls that appear at the bottom of the frame, as shown in the picture
below.
Figure 1 Sample flash demo of VEDA functionality Overall status of the site: -
The
installation section is complete, but the flash demos are very large files.
Sizes will be much reduced in the coming weeks. -
VEDA_FE
section is about 20-25% complete; details on the VEDA_FE home page. This will
remain our top priority till it is covered beyond 80%. -
VEDA_BE
section contains only one flash demo at this point. -
Utilities
section is terse, but gives complete information on the sub-sections that
exist at this point. |
