Open Tool Support for System-Theoretic Process Analysis

چکیده
STPA (System-Theoretic Process Analysis) is a new hazard analysis technique which builds on STAMP, a process and accident model using concepts of system and control theory. In this paper, we present A-STPA an open tool to help transform STPA to an executable STPA which automates the activities of STPA. We develop the A-STPA tool to assist safety analysts in performing STPA. Moreover, it will give the safety analysts different views on the STPA hazard analysis process. We discuss the design of the tool and illustrate its usage. So far, it is still an early version but it can already help the safety analysts in avoiding consistency defects. We are confident that A-STPA will become a powerful tool support for STPA.
