Abstract :
The problem of dynamic service composition of SOA systems based on QoS requirements may be framed as one of automatic generation of policies according to desirable level of QoS characteristics. In this paper, we provide a model driven approach to develop an optimal service composition policies for SOA systems with defined SLAs metrics and QoS constraints. Our work utilizes ideas from Dynamic Programming to calculate optimal policies.
