Abstract
Evaluation model for bucket wheel excavator remaining capability is analyzed in this paper. Model was formed to introduce fuzzy theory in dependability analysis regards to performances of reliability, maintainability and maintenance support, as well for synthesis of dependability from lowest to higher level of excavators’ structure. Dependability was used as the most complex performance which covers in total quality of service for specific technical system and fuzzy sets theory was introduced as a convenient mathematical model that gives mutual synergy to calculations with hybrid data. | Apstrakt
U radu se daje model procene preostalih mogućnosti rotornog bagera na bazi fazi teorije. Formirani matematički model koristi teoriju fazi skupova za sintezu performansi pouzdanosti, pogodnosti održavanja i podrške održavanju, na nivo sigurnosti funkcionisanja, kao i za sintezu ocena sigurnosti funkcionisanja sa nižih na više hijerarhijske nivoe konstrukcije bagera. Sigurnost funkcionisanja je korišćena kao performansa koja na najkompleksniji način sagledava upotrebni kvalitet određenog tehničkog sistema, a teorija fazi skupova kao pogodan matematički aparat koji daje mogućnost računanja sa hibridnim podacima uz njihov međusobni sinergetski efekat. |
