Action systems have proven their worth in the design of safetycritical systems. The approach is based on a firm mathematical foundation within which the reasoning about the correctness and behaviour of the system under development is carried out. Hazard analysis is a vital part of the development of safety-critical systems. The results of the hazard analysis are semantically different from the specification terms of the controlling software. The purpose of this paper is to show how we can incorporate the results of hazard analysis into an action system specification by encoding this information via available composition operators for action systems in order to specify robust and safe controllers.
