UML2SAN: Toward A New Software Performance Engineering Approachijseajournal
Software Performance Engineering (SPE) has recently considered as an important issue in the software
development process. It consists on evaluate the performance of a system during the design phase. We have
recently proposed a new methodology to generate a Stochastic Automata Network (SAN) model from a
UML model, to consequently obtain performance predications from UML specifications. In this paper, we
expand our idea to cover more complex UML models taking in advantage the modularity of SAN in
modeling large systems. A formal description of the generation process is presented. The new extension
gives rise to a serious approach in SPE that we call UML2SAN.

Ver. 1.0 Slide 11 of 26
12. Object-Oriented Analysis and Design Using UML
Stubbed and Complex Transitions (Contd.)
Complex transitions have more than one source or target
state.
If the source of the transition is concurrent substates, then a
join is used to depict the transition.
If the target state is a concurrent state, then a fork is used to
depict the transition.
If the source and target states are concurrent states, then
their joining represents a synchronization of the parallel
threads of control.

Editor's Notes
Initiate the session by explaining the session objectives to the students.
Explain what state diagrams are. Also explain the components of a state diagram.
Explain the concept of state machines, state, initial state, and final state by using the example of Inventory Management System given in the student guide. Explain the concept of an event and the various types of events.
Explain the concept of a transition and the various parts of a transition (source state, event trigger, guard condition, action, and target state). Also explain the advanced features of a state machine by using the examples given in the student guide. When you discuss guard conditions, you need to emphasize the factors that affect the specification of guard conditions. A transition that leaves a branch represents the if- condition. A guard condition shown on a transition represents the definition of the if-condition. The guidelines that you should keep in mind when you design the guard conditions are: * Each transition that leaves a branch element must have a guard condition. It ensures that you have mentioned all the if-conditions that you have thought through all the possibilities for that decision point. * Guard conditions on the transitions that leave the same branch should not overlap. For example, guard conditions, such as x < 0, x = 0, and x > 0, do not overlap as opposed to guard conditions, such as x <= 0 and x >= 0, which overlap. The system will not be able to decide the control flow path when x=0 becomes true. * Guard conditions on the transitions that leave the same branch must form a complete set. For example, if there are only two transitions with the guard conditions, x < 0 and x >0, the system will be unable to respond when x=0 becomes true. * An activity invariant is a condition that is always true when your system processes an activity. A guard condition should not overlap with the invariant conditions and the exit conditions of the activity. Otherwise, it could effect the actions of the activity.
Explain the concept of a composite state. Explain sequential substates and concurrent substates in a composite state.
Explain that the creation of state machine diagrams involves modeling the reactive objects of the software system. Reactive objects are the objects that respond to events by exhibiting a change in the state. The various elements that are essential to model reactive objects are states (simple and composite), transitions, events, actions. Explain the guidelines for creating state machine diagrams.
Explain the concept of submachines and submachine reference states by using the example given on the slide.
