Development of an estimation-experimental method for estimating the preservation indicators of single-use articles

To manage the operation of modern single-use products, it is necessary to evaluate their preservation indicators as uncontrolled, non-repairable, and maintenance-free objects. Data for assessing its parameters are considered one-time censored samples with continuous monitoring, which does not correspond mode storage products during operation. Under conditions limited volumes samples, problematic identify parametric model persistence. solve this problem, a non-parametric estimation-experimental method has been devised, set models data generation, estimation function distribution period indicators. The generation represented by scheme operational tests analytical relationships between quantities tested failed articles. estimating describes process construction on generated data. Models ratios point interval estimates, functionals from restored function. Unlike well-known ones, developed implements assessment under combined censorship. can be used assess articles an error at least 7 %. At same time, lower confidence limits estimated 0.9 worse than 14 % censorship degree more 0.23. agrees well (reliability 0.9, 0.1) actual persistence degrees 0.73, acceptable solving problems managing
