ABSTRACT
There are several advantages in using underground electricity distribution systems (e.g. safety). The increasing use of this kind of the network which is aging, lacks appropriate maintenance and suffers interference from other underground systems has generated many accidents, thus putting human life in danger, and generating consequences for society, the local distribution company and third parties. Furthermore, given the large variability in environments, and hence, there being a wide range of possible consequences when an accident scenario occurs, an approach to risk assessment under a multidimensional view is regarded as being the best suited approach for this context. Another important point is for a model on risk assessment to incorporate the decision maker’s preferences and the uncertainties inherent in this kind of context, using a multicriteria model, based on MAUT, with a view to this being used as a tool for decision-making, which can help risk management, maintenance management and help implement actions (upgrades) to improve the system.
