Smoothing Procedures for an Integrated Approach for Multi-Level Lot Sizing and Detailed Scheduling

Abstract : The integration of production planning and scheduling decisions represents an important challenge in production management. Typical Enterprise Resource Planning (ERP) systems, using Manufacturing Resource Planning (MRP-II) technique for capacity management, cannot guarantee feasible procurement and production plans at the operational level (short term planning horizon). In this paper we study the integrated multi-level lot-sizing and job-shop scheduling problem. We analyze various smoothing procedures that "repair" the relaxed capacity and Bill-Of-Materials (BOM) constraints in the Lagrangian heuristic of a recent approach.
