NEW APPROACH TO ASPECTS
How to interpret double aspect in the reference designation

=A1-K1/+P1
1983:
=A1+P1-K1

NEW APPROACH TO ASPECTS
How to interpret double aspect in the reference designation
Pros:
o Fits with most old IT systems
o Recognized by electrical engineers
2009:
=A1=B1-K1/+P1
Cons:
1996:
=A1-K1/+P1
o Focus on electrical engineering
o Not applicable in other engineering fields
1983:
=A1+P1-K1
o Does not support system thinking
o Reinforces idea about object individual and not
object occurrence
