Classification of type and individual

["Rob Bodington" <rob.bodington@eurostep.com>]

Hi

In PLCS we make a distinction between a typical something and an actual something.

 

E.g

Part and product_as_realized

State_definition and State_observed

 

We are also able to classify things.

E.g.

A Part is classified as a Bicycle

A  State_definition is classified as a Fault state.

 

The question is, if I classify the typical things, do I need to classify the actual thing?

 

For example, if I classify a Part as being a bicycle, do I need to classify the Product as realised as representing my bike, as a being a bicycle, or do I just classify the Part?

 

Similarly for states.

 

If we impose a rule that you only classify the typical – not the actual, then you will always have to exchange both the typical and the actual.

Which may be overkill.

 

Any thoughts?

Regards
Rob
