Safety-centered Architecture Design Method for IMA Software
Chu Wenkui · 2012
Based on adaptation of architecture trade-off analysis method(ATAM),a safety-centered architecture design method was proposed for integrated modular avionics(IMA) software.Hazardous scenarios were used to evaluate the safety property of a designed IMA software architecture.Prevention,elimination or minimization actions to fateful ha-zards were derived.Contracts were used to document all the constraints which should be met in the next refined process of IMA software architecture.With the method,it will eliminate or reduce design bugs in the IMA software architecture,especially those that will contribute to hazards of the IMA system or fighters.
