TY - JOUR PY - 2014// TI - A safety analysis model for industrial robots (Markov chain approach) (case study: Haierplast Company ) JO - Journal of applied environmental and biological sciences A1 - Gerami, Farzad A1 - Ebrahimi, Fatemah A1 - Naderi, Mohammad-Reza A1 - Aghaei, Mir Emad SP - 160 EP - 168 VL - 4 IS - 8 N2 - The growing application of industrial robots in some of the industries and the nature of their activities (vast work environment, unpredictable movements, and the nature of controlling its computer program) will create a unique challenge in occupational safety. An industrial robot must be safe and reliable so that it does not lead to unsafe situations and high maintenance expenses. Consecutive failures of a robot will cause an industry to suffer from great expenses. This study seeks to develop a safety analysis model for industrial robots. The main aims of the research are, identifying potential risks for industrial robots and the definition of hazard rate at different states for a robot system. Due to the importance of this issue and the dearth of studies done in this regard, this study intended to develop a safety analysis model for industrial robots based on Markov chain. Then, this model was applied to the robots in Haierplast Company; and finally, the results were analyzed. The findings of this study include the computation of danger rate, probabilities, reliability, the average of failure time, and the repair rate of the safety system of robots.
