In designing a canal to be built or to be modified, one of the requirements for the entity to construct or modify is to submit a report to Dimar that has the entire engineering engineering specification, as well as to specify the Channel signaling. Dimar Maritime Signaling in one of its many functions must verify that this report has the most appropriate navigation aids and also be coupled to a risk analysis to navigation. In order to optimize the recommendations, a process model for risk analysis to navigation is formulated, formulating a general and specific model, resulting in the implementation of an information system according to the defined process map, including the Disciplines of design, architecture, development and deployment.
