Managing technology development for safety-critical systems 

Date: 11/2004 Author(s): Sachon, Marc; Paté Cornell, Marie Elisabeth Document type: Article in Journal (refereed) This paper presents a model that determines the optimal budget allocation strategy for the development of new technologies, for safety-critical systems, over multiple decision periods. The case of the development of a hypersonic passenger airplane is used as an illustration. The model takes into account both the probability of technology development ...

Delays and Safety in Airline Maintenance 

Date: 03/2000 Author(s): Sachon, Marc; Paté Cornell, Marie Elisabeth Document type: Article in Journal (refereed) Airline maintenance operations affect the potential for flight delays and can also affect flight safety if signals of technical problems are missed or misinterpreted. In this paper, we use a probabilistic risk analysis model, represented by an influence diagram, to quantify the effect of an airline's maintenance policy on delays, cancellations and ...
