A study on Generation and evaluation of Comprehensive Hazard Scenarios for Supporting Safety Design

(Proposal of a Hazard Scenarios Generation System using Petri Net)

Abstract

Recently, unexpected product accidents are increasing due to the multi functionalized and the globalization of products. In order to solve this matter, engineers are required to predict the hazard scenarios fully and comprehensive in product designing. Objective of our study is to develop a system that generate comprehensive hazard scenarios and evaluate them. First, we analyzed accident cases, and then picked up the factors that lead to the product accident. Then, we studied a method how to explain causal relations that bring on state transition such as products contingent on factors’ status or relation by using petri net.
