Papers relating to Success and Advantages of Rule Based Systems

Hi guys,
 
I am working on Jess ( A Java based rule Engine) as a rule base system
to execute the control of HVAC systems.
 
I wonder if there are any papers out there on Rule Based Systems and
their advantages which I can start reading or something. It seems to
me most modern controls are already very advanced (most HVAC
controllers have very advanced classical control hardwares which can
do the job very well) and can do the job very well.

I am hoping for any suggestions or recommended papers which can shed
some light what Rule Based Systems can do but current classical
control cannot. If it is not possible to find such advantage, perhaps
if RBS can do some slight improvement over current classical control,
it will be just as fine.

I have to justify and motivate my decision to use a Rule Based System,
if possible, specifically why Jave based Rule engines like Jess. It is
not necessary to conclusively point that RBS are better or more
superior but , hopefully I can find something that can shed some light
on their differences and merits of RBS in relation to current
classical control.


Many thanks !!
