%D 2012 %T Functional modeling applied to HAZOP automation %C Singapore %A José Luis de la Mata San Marcos %A Manuel Rodríguez Hernández %X In this paper we present a new tool to perform guided HAZOP analyses. This tool uses a functional model of the process that merges its functional and its structural information in a natural way. The functional modeling technique used is called D-higraphs. This tool solves some of the problems and drawbacks of other existing methodologies for the automation of HAZOPs. The applicability and easy understanding of the proposed methodology is shown in an industrial case. %B Proceedings of the 11th International Symposium on Process Systems Engineering %L upm20454 %K Functional modeling; HAZOP; Risk assessment %I Elsevier %P 255-260
