Abstract

This paper presents a subjective safety and cost based modeling approach for evaluating safety requirements specifications in the study of safety-critical software. In the approach fuzzy set modeling and evidential reasoning are combined to assess both the safety associated with and the cost incurred in each option of safety requirements specifications. Both safety and cost estimates are combined to obtain the preference degree associated with each option of safety requirements specifications for selecting the best one. An example is presented to demonstrate the proposed approach for safety based on decisionmaking in safety requirements analysis of safety critical software development. © World Scientific Publishing Company.
