Designing and comparing schedule-based manufacturing with MRPII

Abstract

Schedule-based Manufacturing (SBM) is a paradigmatic shift in Manufacturing Planning

and Control (MPC). It is a migration from the MRPII methodology. The approach of MRPII is largely procedural and is basically top-down, however SBM aims to adopt an integrated and responsive methodology capable of meeting the ever changing and

increasing competition in market demand. Unlike MRPII, SBM merges the vertical

separation of Master Schedule (MS) and Production Schedule (PS) by directly

transforming master orders to scheduled works orders. It effectively resolves the

differences between Material Requirements Planning (MRP) and Capacity Requirement

Planning (CRP) by using the Bill of Manufacture (BOMF) instead of Bill of Materials (BOM). SBM is in fact an integrater of production planning and scheduling, it can provide an integrated solution to materials and resources for manufacturers [2].
