  12. M R P • Diperlukan untuk pengelolaan barang yang sifatnya saling bergantung (dependent). • MPR tidak saja merupakan sistem pengendalian material tetapi juga merupakan sistem produksi dalam artian yang lebih luas. • Berupa mekanisme yang secara logika sangat rendah tapi membutuhkan persyaratan sistem informasi yang baik. (Computer Oriented Approach) Senator Nur Bahagi@

  13. MRP System Input Mechanism Out-Put JIP Netting POR Material Product Structure Lotting POR Process Inv. Status Offsetting Revised Schedule Exploding Cancel Order Senator Nur Bahagi@
