Assessing the Software Control Autonomy of System Functions in Safety-Critical Systems

Software Control Category (SCC) denotes the degree of control autonomy, command and authority, redundant fault tolerance software has over hazardous system functions safety-critical systems. The use SCC for determining contribution to risks is a unique feature MIL-STD-882E System Safety Standard. A lower designation means that greater autonomy functions, whereas 1 complete autonomous control. with require effort assure reliability safety. Correct assessment level crucial optimizing safety property developed under budget, schedule, resource constraints. Beyond categorical definitions provided by Standard, there little information on conducting an assessment. To close this knowledge gap, we present method. Our paper will describe in detail process rules assessing SCC. For illustration, apply our method assess several safety-significant automobile’s brake-assist system.
