Proposition of psyche entropy analysis and its application
Along with the continuous improvement on the reliability of machinery and electronic devices,system safety increasingly depends on human behavior.When people are in poor mental state,they may be out of control to make certain unexpected mistakes which will result in accidents possibly.Therefore,to analyse the unconscious human errors and bring forward the measures which will improve the situation can promote the safety level of the whole system as well as decrease the risk of the accidents.The concept of psyche entropy analysis was proposed in the paper as a method to figure out the above issue.Based on safety principles,psychology and safety ergonomics,six indicators for the calculation of entropy method were put forward.The method was implemented before the workers were on duty.The workers evaluated themselves by giving the score of the six indicators and calculated the total score they finally gain which was the representation of the their psychological state.Then the manager may enquire about the low-scoring items according to some principles to find the questions and their solutions.Finally we can reduce and control the risk of the accidents caused by unconscious human errors.
