ABSTRACT

Concern with preserving the environment has been observed in different segments of world society, given the constant changes that have been occurring all over the globe. Consequently, environmental issues are increasingly incorporated into studies and discussions in different sectors, and have received special attention in some risk management models. In this context, this paper presents a multicriteria decision model in order to evaluate natural gas pipeline sections and define actions in order to mitigate the risks involved in these transportation modes. Thus, the environmental focus is considered by incorporating the environmental dimension into the model along with two other dimensions: human and financial In this multidimensional assessment, Multi-Attribute Utility Theory (MAUT) is incorporated into the model. The analysis by the ratio of the increments of risk enables the decision maker to analyze the sections considered more consistently and thus makes it possible for him/her to structure planning actions better, as well to allocate resources better. This also provides a wider pool of information for the decision maker.
