Drools Compound OR rule in Excel sheet

Question

I have thousands of rules written in excel sheets so I can't easily move away from that unless there is a good reason. Also using version 5 of Drools and cannot easily upgrade. Using Drools Guvnor for managing and compiling rules.

I have the need to write a massive compound rule and I am struggling on how to do it.

Facts: width, length, part number

Rule need to be written:

   for a specific part number
        outside of dim range w1 x l1 then can't use Adaptor1
        outside of dim range w2 x l2 then can't use Adaptor2
        outside of dim range w3 x l3 then can't use Adaptor2
        outside of dim range w4 x l4 then can't use Adaptor3
        if no adaptor can be used then you can't use Base1

I need to know which Adaptors are not allowed and which Bases are not allowed.

Any ideas on how this can be written in an excel sheet.
