Using inheritance to derive non-conflicting survivability strategies

Interoperable survivable systems need to be specified taking into account a total systems perspective. A survivability strategy can be described by enumerating its objectives, which are modeled as the properties (or attributes) of a survivable system specification class. These properties represent different aspects of a fault-tolerant communications system. A survivability specification class specifies a particular technology family such as a class of centralized control architectures. Classification allows common features of a survivable system to be packaged in a class, and new technology requirements, which adds new capabilities, to be specialized from the common class
