Decision Support System for Classification of Natural Risk in Maritime Construction

The objective of this paper is the prevention of workplace hazards in maritime works – ports, drilling and others – that may arise from the natural surroundings: tides, wind, visibility, rain and so on. On the basis of both historical and predicted data in certain variables, a system has been designed that uses data mining techniques to provide prior decision-making support as to whether to execute given work on a particular day. The system also yields a numerical evaluation of the risk of performing the activity according to the additional circumstances affecting it: the number of workers and the machinery involved, the estimated monetary cost of an accident and so on.
