This paper illustrates a subjective safety-cost based design-decision support framework using fuzzy logic and evidential reasoning approaches. The framework is divided into three parts. The first one is for safety analysis and synthesis including fuzzy rule-based safety estimation using the fuzzy rule-based evidential reasoning (FRB-ER) approach, as well as the safety synthesis using the eviden...

This paper presents a novel Human Machine Interaction (HMI) design/evaluation methodology, supporting the specification and evaluation of a new adaptive automation concept, both from a functional and an operational/safety perspective. This methodology has been advanced as part of the work requirements for the Applying Pilot Models for Safety Aircraft (A-PiMod) project, funded by the European Co...

The humidifier disinfectant disaster (HDD) was not a simple poisoning accident by biocides, but a singular disaster in history created by chemicals in household products. This disaster was a result of the failure of a system for the management of chemical and product safety. Since the management authority for chemical usage safety is different from those for chemical safety in products, many bl...

Based on the results of investigation and the suggestion from the experts, the factors influencing the college canteen food quality and safety are found and assessment system for university cafeteria food quality and safety is constructed. With the improved Analytic Hierarchy Process (AHP) to the various indexes for the empowerment and the fuzzy comprehensive evaluation method, the university c...

For any software system upon which lives depend, the most important question one can ask about it is, ‘How do we know the system is safe?’ Despite the critical importance of this question, no widely accepted, generally applicable answer exists. Instead, debate continues to rage over the question, with theorists and practitioners quarrelling with each other and amongst themselves. This paper sug...

Safety assessment of thermal power plants (TPP) is an important means to ensure the safety of production in thermal power production enterprises. Modern information technology can play an important role in TPP safety assessment. The evaluation of power plant systems relies, to a large extent, on the knowledge and experience of the experts undertaking the task. Case-based reasoning (CBR) is intr...
