Derivation of Stochastic Reward Net (SRN) From UML Specification Considering Cost Efficient Deployment Management of Collaborative Service Components

Performance evaluation of distributed system is always an intricate undertaking where system behavior is distributed among several components those are physically distributed. Bearing this concept in mind, the authors delineate a performance modeling framework for a distributed system that proposes a transformation process from high level UML notation to SRN model and solves the model for relevant performance metrics. To capture the system dynamics through their proposed framework, they outline a specification style that focuses on UML collaboration and activity as reusable specification building blocks, while deployment diagram identify the physical components of the system and the assignment of software artifacts to identified system components.
