There are many known modeling paradigm s to describe the System dynamics dynamics of system in Process oriented programming process oriented , Event based programming event based and activity based view points. Among those modeling paradigms, the activity based modeling is a natural way to represent the activity paradigm of discrete event simulation and our knowledge about a system. In activity based modeling ref http www.informs sim.org wsc97papers 1127.PDF ref , the dynamics mechanics dynamics of system is represented as an ACD activity cycle diagram which is a network model of the logic al and temporal relationships among the activities. An ACD is easily implemented with the activity scanning method of simulation execution ref http www.thesimguy.com articles simModMeth.pdf ref .

Communication diagrams represent a combination of information taken from Class diagram Class , Sequence diagram Sequence , and Use case diagram Use Case Diagrams describing both the static structure and dynamic behavior of a system. However, communication diagrams use the free form arrangement of objects and links as used in Object diagrams. In order to maintain the ordering of messages in such a free form diagram, messages are labeled with a chronological number and placed near the link the message is sent over. Reading a communication diagram involves starting at message 1.0, and following the messages from object to object. Communication diagrams show a lot of the same information as sequence diagrams, but because of how the information is presented, some of it is easier to find in one diagram than the other. Communication diagrams show which elements each one interacts with better, but sequence diagrams show the order in which the interactions take place more clearly.
