Q: 

Decision table with large number of conditions and actions

Hi all,

If the number of conditions and actions is high (in my case, 12 conditions and 13 actions respectively!), making/maintaining a decision table with hand is proving to be really tough. The number of possible rules in the case at hand is huge (Y/N for 11 conditions and a 3-way choice for the 12th) and it's freaking me out. Also, these conditions and actions cannot be collapsed/coalesced; they are all needed very much.

What could be a better alternative to a decision table? What are some popular free tools to model the same?

Thanks so much.

A: 

Have a look at ROBDDs.

Thanks...can you pls. point me to a book that explains creation and reduction of BDDs in a simple way?

The wikipedia article links to some articles and books.

By the way, why would an ROBDD be suitable for my model in question? I am not really looking at a binary 0 or 1 answer....I am looking at 8-9 possible actions to be taken based on the combinations of values of 11-12 conditions .... correct me if I am wrong, but an ROBDD doesn't seem intuitive to me here.

You can encode a condition for each action and test them efficiently with ROBDDs.

Yes, that's what I meant.

A: 

Statestep might be what you're looking for. Really powerful for dealing with large numbers of possibilities. Not normally free though, unless for education etc.
