The objective of the article is to propose a design for the Socio-Technical Maintenance Network “DFMSN” of the equipment of small agri-food units in West Africa, while considering significant indicators of this network in particular, the duration of the supply, the costs and life of spare parts of similar equipment, with good operational availability. We propose guidelines similar to design rules used as design aids. A local design team has been applied to demonstrate its applicability and validation. The result feedbacks are relevant however, other similar design experiments are needed to enrich the DFMSN.
