9.9 Advanced Flow Modeling
In SysML, there is a default assumption that tokens flow at the rate dictated by the executing actions and that tokens flowing into an object node flow out in the same order and with equal probability. SysML offers constructs to deal with situations when these assumptions are not valid.
9.9.1 Modeling Flow Rates
Any streaming parameter may have a rate property attached to it that specifies the expected rate at which tokens flow into or out of a related pin or parameter node. Note that the attached rate annotation does not refer to the rate at which a node’s value changes over time. Continuous flow is a special case that indicates that the expected rate of flow is infinite, or conversely the time between token arrivals ...
