Components can be assembled based on the Service-Oriented Architecture (SOA), which allows enterprises to specify their services in a finer granularity, thus the services can be expressed in a deeper and more comprehensive manner. This paper makes use of the formal description of the service component, the Hierarchical Automata, studies the importance factors of each component and roughly categorizes them into different rankings, which reflect different component quality criteria (i.e. availability, reliability and dependability within the scope of this discussion, refer to Section 3.2), through mapping functions, and thus the appropriate components can be selected based on their importance factors and quality parameters, and then proposes an algorithm to calculate the resulting system reliability, and finally studies a case to demonstrate the selection of components and the resulting reliability.
