XYZ alsomanufactures their products too. For the time being, PT. XYZ in manufacturing the products have aproblem, the problem is the schedule for finishing the product is always late and not accurate on thetimeline. The purpose of this research is to prevent production schedule tardiness and improve rawmaterials requirement planning at PT. XYZ. To find the root problem, current reality tree (CRT) is used.There are several root problem collected from the CRT, but the selected root problem for this researchare poor inventory management for raw materials and poor material requirements planning. The methodused in this research is Material Requirements Planning (MRP). To create an MRP, there are severalsteps to become the input of MRP, they are aggregated forecast demand, aggregate planning, masterproduction schedule (MPS), bill of materials (BoM), and inventory records file. All those stepsmentioned before are proposed in this research too, to help PT. XYZ preventing production scheduletardiness. The result of the proposed MRP are gross requirements of materials required for certain unitof vehicle production, planned order receipt, planned order release, when and how much materialsshould be needed to produce vehicles in the planning horizon. With this MRP, PT. XYZ could plan abetter raw materials requirement, then schedule tardiness could be prevented or minimized, thus helpsPT.
