| Research Abstract |
The present situation and the trend of safety regulation system of Japan, US, and Europe were investigated and compared, and the following features were revealed for the safety regulation of each country. In US, the regulation codes and regulation guides describe function requirements, and they refer to nongovernmental technical standards, which determine concrete specifications of facilities and activities. Almost all regulatory guides in Europe (France) also describe function requirements, and it is the responsibility of operators to determine specific technical standards. In Japan, decrees and notifications include specific technical standards, and it sometimes becomes a barrier for the regulation to follow the progress of technology. As for the system of regulatory inspection, the conformity assessment program is well established for the ASME code system in US. Nongovernmental organizations certify authorized inspectors and inspection agencies. The training and certification system

of inspectors in the regulatory body is also clearly defined and organized. Such a certification system of technical abilities of inspectors has not yet been well organized in Japan. From the above findings, some proposals have been made to improve the present regulatory system of Japan.
A social simulation has been proposed next for assessment of safety regulation systems. The simulation model used is a multi-agent system where companies conduct production and evolve under given conditions. Each company allocates its business resource to production and safety management, and the reliability and the productivity of the facility are determined. Many simulations were executed varying the style of safety regulation, and then the results were compared. The following are the findings of these simulations. The penalty-based regulation, for example, can improve not only safety level but also productivity level, and specification-based regulation may have effects opposite to the expected one. Surprise inspection is effective than periodical inspection though the interval of inspection is long. These findings show that the social simulation is very useful to assess what style of safety regulation is more effective than the others. Less
