The presented study is in the field of the decision-making aid for the monitoring and the diagnosis of complex systems such as chemical processes. Our work permitted to design a methodology allowing placing the most relevant sensors on a process for its diagnosis from the analysis of historical data. This methodology is based on the association of methods used for measurement of information quantity (Shannon's entropy) delivered by signals coming from a system and for the classification of data. From time evolution data of sensors (constituting the set of all possible sensors) following scenarios of failure (for example simulated on a dynamic simulator), it is possible to identify the most relevant sensors in the set of the possible sensors...
