The functional matching permits to eliminate web services that fail to(More)
There is a need to facilitate learning from failures in the context of natural and manmade disasters. This paper investigates the multi-faceted nature of research in disasters and the aspect of hybrid approaches in modelling within this domain. The paper applies a framework of reliability and multiple criteria decision analysis techniques to the case of the(More)
