Value port

A willingness to provide or request value objects.

Name. Unique name of the value port.
Role. In or out. Derived value.
Occurrences. Positive integer indicating the number of times a value port is triggered in a market scenario. Derived value.
Cardinality. Positive integer that indicates the number of copies of a value object that is transferred when the port is triggered. Default value is undefined. During model analysis it is checked that the cardinality of at most one port of each value transfer is defined.
Valuation. The value assigned by the actor to the value object passing through this port. Default value is undefined.
If you set the valuation of a port in a diagram, it must be connected to a transfer. If this is a money transfer, then the valuation of the port at the other end of the value transfer must be undefined. If it is a non-money transfer, then both ports may have a valuation and these valuations may be different.
Expenses. Variable expenses made in one occurrence of the port. Default is 0.
