title: [Functional modeling for risk analysis in radiotherapy].
abstract: OBJECTIVE
  This document presents a systematic and structured approach for functional modeling for risk analysis in radiotherapy, aiming to reconcile the need, on one hand, for a method that can be applied generally and, on the other hand, for a method that provides a highly precise model.
  
  
  METHODS
  The approach relies on new functional structuring patterns and flux analysis, derived from system engineering and knowledge engineering.
  
  
  RESULTS
  The method affords strong support for the development of detailed models of the patient's process through a department of radiotherapy. Lack of structure of the actual process in a particular department may be easily identified leading to the development of specific procedures for the improvement of security.
  
  
  CONCLUSIONS
  Modeling approach derived from engineering may be used for functional modeling for risk analysis in radiotherapy.
