Can i use prolog?

Hello mates,
I am stuck on a problem and was wondering if prolog could be the answer. 

The problem is that i want to use some decision making system to optimise a 
process which has a lot of control variables. Some of these variables are 
interrelated through simple equations, whereas other variables are 
qualitative in nature. 
 
 For example for a live wire,we can have a relation that 
Voltage=Current*Resistance. 
 This is a simple quantitative relation. But if this wire is hanging on a pole 
in the open then i can say if the windspeed goes up, the voltage can go down 
(i.e. cable may snap). Now this would be qualitative relationship. 

For qualitative reasons, i just want to display the results on the computer 
and not ask the computer to come up with a reasoning(we dont know the 
physics). 

My objective is to make a decision tree/table for the whole process. Can 
prolog help me?

cheers
