Abstract. During the last few decades of the 20th century, there have been intensive efforts to study human errors as an essential element of quality and safe functioning of complex systems. To perform a human error analysis, it is necessary to provide adequate data, to process the data properly, to connect different databases, and to select adequate methods for human error identification and quantification. Therefore, human error analysis and identification is the most important part of human reliability assessment. Human error analysis considers the role of humans in the occurrence of hazards or risk. It usually pertains not only to human error identification, but also to the preliminary identification of error reduction measures. This paper presents the procedure of human error identification and modeling in the Electric Power Company of Serbia by means of an event tree analysis. The paper particularly focuses on the primary causes of accidents in electric power distribution companies and emphasizes the importance of understanding the effects of human errors on occupational and environmental quality.
Key Words: human factor, human error analysis, human error probability, event tree analysis

PRIMENA STABLA DOGAĐAJA ZA ANALIZU LJUDSKIH GREŠAKA U ELEKTROPRIVREDI SRBIJE
Poslednjih decenija XX veka intenzivno se radi na proučavanju ljudskih grešaka kao važnog elementa kvaliteta i bezbednosti funkcionisanja kompleksnih sistema. Za analizu ljudskih grešaka potrebno je obezbediti adekvatne podatke, kvalitetnu obradu informacija, izvršiti povezivanje različitih baza podataka i napraviti odgovarajući izbor metoda za identifikaciju i kvantifikaciju ljudskih grešaka. Zbog toga je analiza i identifikacija ljudskih grešaka značajan segment u proceni ljudske pouzdanosti. Analiza ljudskih grešaka razmatra ljudski udeo u nastanku neke opasnosti i rizika. Ona se obično odnosi ne samo na identifikaciju ljudskih grešaka nego i na preliminarnu identifikaciju mera za redukciju grešaka. U ovom radu prikazan je postupak identifikacije i modelovanja ljudskih grešaka u Elektroprivredi Srbije primenom analize stabla događaja. Poseban akcenat dat je razmatranju osnovnih uzroka akcidenata u preduzećima za distribuciju električne energije i ukazano je na značaj razumevanja efekata grešaka čoveka na kvalitet radne i životne sredine.
