Service-Oriented Architecture (SOA) is a software architecture design pattern based on discrete pieces of software providing application functionality as services to other applications. Before application of SOA, if a model of problem is drawn and analyzed, then possible flaws in architecture implementation phase could be prevented. This paper presents a method for evaluating SOA based on formal models. To achieve this goal, products of C4ISR framework are calculated and then are marked on UML diagrams to get the real model. For this purpose, the UML elements should be indexed according to efficiency.
