Unified Modeling Method of Heterogeneous Resources for Multi-platform Avionics System Based on AADL

Currently, single-platform avionics system modeling often uses service-oriented modeling methods to describe service-oriented architecture (SOA). However, for the multi-platform avionics system, the traditional modeling method can not represent the heterogeneous resources uniformly; and the description method of the relationship between services and resources is lacking. To solve these problems, this paper proposes a modeling method based on architecture analysis and design language (AADL). The heterogeneous resource pool model is constructed by unified description of heterogeneous resources internally and externally. In addition, a service-oriented approach is used to match function servitization with resources. This method is used to model a multi-platform avionics system. The example shows that this method can abstract heterogeneous resources in the same way, support multiple types of resources, and describe the relationship between services and resources in the task scenario.
