4. Management of sustainable production systems

4.1 Special features of sustainable systems management

While in the operating phase of a control system, the input signals and variables are identical to those of a traditional system, the particularity of a sustainable system lies in the desire to observe a maximum number of internal and output signals and variables (paradoxically inducing a non-negligible environmental cost of data capture and memorization) to determine the adequacy of the means used to the objectives set, whatever the complexity inherent in this observation. For example, CO ₂ emissions or energy consumption induced by the execution of an instruction are more complex to observe than an operating parameter such as speed, production time or number of parts manufactured....
