'T weighted allocation method.Throughintroducing the bottomTheessence ofreliability allocation isaproject unascertained information into thematrix ofweight coefficients, decision-making question whichhasstrong uncertainty. Itis theunascertained modelforthereliability allocation ofa difficult, evenunableto be described by classical spaceborne antenna deployment mechanism isbuilt. Bymeans mathematics. Thisuncertainty comesfromtwoaspects: One ofthearithmetic operation rules ofunascertained rational isthat agreat dealoffactors needtobeconsidered inthe number, theexpression ofunascertained weighting coefficient is reliability allocation, such astechnical level, complex degree, derived. Finally, thereliability allocation ofa spaceborne. ' . . .' .r antenna deployment mechanism isgiven asanexample.
