Upon increasing application of unified modeling language diagrams for description of enterprise architecture and importance of evaluating the non-functional requirements in the enterprise architecture, establishing an executable model of these diagrams is necessary. On the other side, unified modeling language diagrams have not the capability of evaluating the non-functional requirements of system directly. The simplicity and characteristics of these diagrams must be reserved and the capability of evaluating these requirements to be incorporated thereto. To achieve this goal, an executable model of these diagrams to be Created. In this paper, it is assumed that architecture of a system has been described by two use case and collaboration diagrams of unified modeling language. The role of these diagrams in evaluation of reliability and annotations related thereto has been examined and extended by a algorithm to an executable model means colored Petri net. In this study, the procedure of establishing an executable model that can analyze the reliability of artifacts in C4ISR framework. According to the results obtained from simulation of this model and their analysis, we could identify the problems in planning phase and improve out artifacts in order to avoid the extreme time and economic costs of implementation.
