If you do believe that your industrial system is really complex, then

In order to evaluate the complexity of a large system, a typology proposed in 1948 by W. Weaver, (‘Science and Complexity’) suggests that we differentiate models as disorganized and as organized complexity. In order to take into account the effective role of the ‘observing system’ in the modeling process, the paper suggests to transform this typology and introduce a concept of ‘organizing complexity’. Reviewing the rich experience acquired since 1948 in modeling complex systems, it identifies two basic principles: the Principle of Intelligent Action, and the Principle of Systemic Modeling. An epistomological discussion leads the paper to reconsider the methods and the languages often used in the modeling of industrial systems and to suggest an alternative language for handling their complexity more effectively.
