Information : Manufacturing Resource Planning and Production Management System
The Manufacturing Resource Planning and Production (MRP II) system at Lockheed Martin Tactical Aircraft System (LMTAS) is an electronic closed-loop system that maintains cost accountability for the material flow process. It efficiently provides the correct quantity of required materials at the needed time and place, and maintains accurate records of all material flow information. The system includes Master Scheduling, Bills of Material, Inventory Control, Shop-to-Floor Control, and Purchasing Management. Accuracy for the data maintained by this system is 99% to 100% for Master Scheduling, 99% for Bills of Material, and 98% to 99% for Inventory Control.
The Purchasing Management System which resides in the MRP II system is a user-friendly, menu-driven system used to track material purchases from the initial creation of the purchase order requisition to acceptance of the material in receiving and stock. It enables the planner to create purchase order requisitions according to system specifications, use standard text and the purchase order request to build the Request for Offer, and automatically create the purchase order from data on the Request for Offer. It also is a large repository for information related to the procurement process. Workload reports, purchase order histories, and dock-to-stock transactions are created and monitored using this system. Additionally, the system maintains an on-line vendor information resource providing such information as approval levels, certifications, delivery performance, and status of open purchase orders for each vendor.
The Purchasing Management System is a valuable asset to the MRP II System. It has reduced the levels in inventory, reduced the occurrence of shortages, promoted on-time supplier delivery schedules, induced improved pricing, shortened lead times, and provided improvement in product quality. This proven track record, combined with the accuracy shown within the other subcomponents in the MRP II system, has provided a high-confidence-level material flow tracking/cost accountability system for Lockheed.
