Production Planning systems balance demand forecasts, material availability, and resource capacity to generate optimized production schedules across facilities. Core capabilities include master production scheduling (MPS), material requirements planning (MRP), capacity planning, work order management, shop floor scheduling, demand-supply balancing, and integration with ERP, inventory, and procurement systems. The category spans enterprise planning modules within ERP suites (SAP PP, Oracle Manufacturing Cloud) and dedicated production planning tools (Opcenter/Siemens, Plex, DELMIA Ortems) that serve discrete, process, and mixed-mode manufacturers.
