This paper proposes a modelling and formalizing approach to fieldwork-collected data in order to develop a set of tools to both direct and increase industrial production. The OCP (“Cherifian Office of Phosphate”) provided authentic data for the construction and use of an inductive approach. This approach enabled us not only to give details about the problems encountered but also to have the necessary level of granularity required for a number of ex ante management decisions. Several instances of the suggested modelling applications are given in the real context of the OCP’s supply chain reengineering. They equally allow the reader to obtain a feedback on the implementation of a twofold modelling generated by a unique collection of knowledge.
