Connection of one individual to another
Two instances of subtypes of PossibleIndividual may be connected, but maybe not. Rules determining when it is possible, and technically feasible, can be defined as instances of ClassOfDirectConnection or ClassOfIndirectConnection with the appropriate cardinalities (not shown here).
The little model for that is:
Pump is directly connected to Pipe
In case you want to put on record which materials have been used for the connection, you can use the following extension of above model.
A gasket has been used to connect a two flanges
The analysis diagram for the first case is as follows.
NOTE - The diagrams also apply for indirect connections, just change the word Direct into Indirect.
