Safety critical systems involve the tight coupling between potentially conflicting control objectives and safety constraints. As a means of creating a formal framework for controlling systems of this form, and with a view toward automotive applications, this paper develops a methodology that allows safety conditions—expressed as control barrier functions— to be unified with performance objectiv...

Purpose The purpose of this study is to establish a systematic framework characterise the safety air routes, in terms separation minima infringements (SMIs) between en-route aircraft, based on definition models known as performance functions. Design/methodology/approach Techniques with high predictive capability were selected that enable both expert knowledge and data be harnessed: Bayesian net...

safety performance is the overall performance of the organization safety management system in the operational system of safety. in the present study, the components of safety performance included visible management leadership, employee participation, training, inspection, implementation tools, and maintenance. the objectives of this study were to assess safety performance, and to analyze differ...
