Abstract

Safety is increasingly recognised as an important property of a software system. The safety of a decision support system is a property that ensures that actions recommended by the system will have minimal undesirable consequences. The objective of this paper is to proposes a logical formalism for reasoning about the external safety of a decision support system. The proposed logical language makes provision for representing time, preferences, actions and also deontic and safety related operators such as “obligation”, “safety” and “authorisation”.
