Application of an MRP matrix-based hierarchical planning model to a furniture company

This paper is concerned with the definition of a feasible master schedule for operations management, obtained through an integrated planning system, using a hierarchical methodology (by means of different disaggregation stages) with an appropriate time horizon for connection with the manufacturing requirements planning unit (MRP II).
