Study On Safety And Human Reliability Analysis In Large-Scale Systems

Along with various types of equipment, processes and systems become more and more complex,large-scale and highly automated,the demands of the Human- Machines - Environment system's security and reliability become increasingly higher. So in the system the impact of human and its faults increasingly become prominent. And because of person,self has characteristics such as degeneration, nonlinearity and randoms, influencing human error factors numerous and extremely complex, involving extremely broad scope of disciplines,it is quite difficult; Plus China in this field of system late start, so in theory and in practice there are still large gaps。Based on this, this paper,in the study profits from the overseas related research results in the foundation, has made a more thorough research on the fault factors to the human, induces it into the society, the psychology, the physiology, the knowledge/skill as well as the duty (position) these five aspects。At present ,domestic is still in the situation of lacking complete accident statistics data (database) and some certain factors are difficult to quantify, in order to be advantageous for the project to make the simplification practical to certain factors,and attempt using the fuzzy evaluation method to computate the danger coefficient of human。Simultaneously the application analytic hierarchy process carries on the risk assessment to system's security, carries on the computation analysis comparison to system's each expiration factor, and determines the latent hidden danger. The paper works, although mainly aims at the preliminary discussion which because in the industrial production system's person affects launches; As it further thorough and the imperfectness, it will has profits from the function to person analyzes on system's securities and reliability design appraisal of astronautics, nuclear power station and weaponry and so on。...
