Found Message
Found Message  
A found message is a kind of message where the receiver (event occurrence) is known but the sender (event occurrence) is not known. It is assumed that the sender exists but is outside the scope of the model.


A found message is a message that is received but for some reason the sender is not known or is not identified. This is typically because the sender is not of interest in the context of our model. In our everyday life messages can be received but the senders may be outside our interest for example: when we receive spam we typically are not interested in the sender. Noise in a communication system is another example of messages that are received but the sender can often not be identified. It is important to understand that while the sender may not be known the message itself may be important, for example: in devising devices to deal with noise or spam within an operational system.
