摘要

Disclosed is a risk analysis support device 100 to prevent neglect by an executor that performs a risk analysis and shorten analysis time. The risk analysis support device 100 includes: a control structure diagram input unit 111 which receives an input of a risk analysis target represented in a form of a control structure diagram that represents the risk analysis target by a block and a control showing a relationship between a block executing control and a passive block controlled by the block; a control loop search unit 121 which searches in a database 140 for a similar control structure diagram including a subset of controls that matches or is similar to a subset of controls extracted from the control structure diagram whose input is received by the input unit and acquires from the database 140 a hazard scenario including a node having a correspondence relationship with a subset of controls included in the similar control structure diagram; and a recommendation output unit 123 which outputs the acquired hazard scenario in a tree structure.
