Material Requirements Planning

Your company goals for a Material Requirements Planning (MRP) system probably include reducing:

  • WIP
  • Raw Materials
  • Finished Goods Inventories
  • Order change resistance
  • Expediting
  • Delinquent Orders

In the past, software powerful enough to accomplish these goals required expensive hardware, with a less-than-user friendly operating system. JAMS introduces a new alternative.

MRP: Not Too Much Too Soon

Your company just received a large order from a new account. Initial deliveries begin in six months. The sub-assemblies on the 4th level of the Bill of Material have a 120-day lead-time on the raw material components needed to manufacture. How will the purchasing and delivery of that material affect not only your investment in inventories, but also other orders from existing customers? The answer to this and other questions is the JAMS MRP Module.

The MRP Generation Program determines which parts and sub-assemblies are required to fulfill demand. All lead, queue, manufacturing, and outside processing times are calculated for each part or sub-assembly. The beginning date for the purchasing of parts or manufacturing of sub-assemblies is calculated and made available on the various MRP screens and reports. Work orders and purchasing requirements are generated so jobs may be scheduled and all required parts ordered.

Non-MRP tracked items can be added to the respective BOM for release to the manufacturing floor. This ensures that all required parts, tools and information are available to manufacturing upon release of a work order.

MRP Regeneration

The JAMS MRP Module will support two methods to determine the resources required for manufacturing demand:

Incremental Regeneration
This method determines manufacturing requirements by updating the resource file with changes that have occurred throughout the day. The interval of the IRG is user selectable and can be time or transaction based.
Full Regeneration (FRG)
This method determines manufacturing requirements by a complete analysis of all demand. After a successful run, the old resource requirements are cleared and replaced with the newly calculated requirements.
