Submit a textual CID-Graph and receive a Fault Tree Postscript File

To use cid2ft-Service you have to follow these steps:

If your cid file requires additional files for (safety) sub-systems, these files will be requested by the cid2ft service in another step. The names of the requested files will be displayed, It is neccessary to specify all the additional files or cid2ft will not be able to complete your request.

After processing your file(s), and if all went well, the cid2ft service will offer a Postscript[tm] file (but see below!) containing a Fault Tree diagram corresponding to the CID file(s) uploaded. Save the file to a convenient place to your hard disk and view it with a postscript viewer of your choice.

Here is a short Manual for cid2ft, describing basic features and requirements for cid files.

For a more in-depth discussion of Causal System Analysis (CSA), Causal Influence Diagrams (CID) and automatic generation of Fault Trees from CIDs, see the following papers by Prof. Dr. Peter B. Ladkin et. al.:

Textual CID-Graph:
Prepared glossary file:
(Only used if using "Use previously created glossary file")
Do not use glossary
Create glossary file
Use previously created glossary file
If you choose to use automatic label replacement using glossary files, you need to perform three steps:
  1. Choose "Create Glossary File" on the left.
    Beware that the downloaded file in that case is not a Postscript file containing the Fault Tree, but instead it is a special glossary file.
  2. Edit the downloaded glossary file. It is mostly self-explanatory, just fill in the labels that you wish to appear in the final Fault Tree instead of the automatically generated explicit pre-post-conditions.
  3. In the third step, you need to choose "Use previously created glossary file" and select (below) the file you downloaded and edited in the first and second steps.

Size of the generated Postscript Graph
A4 put the whole graph on a single landscape page
A3 combine 2 portrait pages giving an A3 sized graph
Long distribute a long narrow graph on 2 landscape pages
Large create 3 portrait pages for a large graph

Comments, bug reports and suggestions for enhancements are welcome.
