Conventional Usage of Finite State Machine over Petri Net inWeb Service Change Management Framework

Finite state machine and Petri nets are one among the various conceptual and computational models that have been widely used in analyzing diverse web service research areas. In this paper a comparison of using finite state machine and Petri nets for modeling a web service change management framework is analyzed with experimental analysis. Though there are many existing change management approaches to satisfy the normal changes, they fail to there is no proper support for efficient change evaluation and monitoring. Also complex structure called Petri nets is used to model the overall system functionality when a change whereas simple finite state machine can be used for the same representation since the process of change management only includes emergency and minor changes. Using FSM, only a specific logic can be extracted instead of exacting the overall function as in case of Petri nets. Thus for the evaluation of changes implemented, FSM is very efficient for the representing the overall change management. In this paper, we are going to see how FSM is efficient in modeling the change management and also the evaluation of changes implemented using certain change factors when compared to Petri nets.
