1 Supply Chain Execution Systems Warehouse Management Systems Lecture Resource Adapted with permission from presentations by John Hill, © 2002, 2003 John M. Hill, ESYNC

2 Supply Chain Execution Systems (SCES) Manage inventory, space, material handling equipment, labor, and transportation resources in real time to assure timely, error-free fulfillment, delivery, and visibility of order status throughout the supply chain Matching material and information flow

3 SCES Impact Areas Fulfillment Delivery Visibility Responsiveness

4 Fulfillment and Delivery Material handling and controls Right condition AutoID and data collection Right material Supply chain execution systems Right time People Necessary for all of the above

5 Responsiveness The best decision making is executed on the basis of events as or before, not after, they occur Responsive logistics systems provide discipline and control that is based not only upon plans and performance goals, but also upon the dynamics of actual operations

6 SCES Components Warehouse and Labor Management Transportation Management Yard Management International Trade Logistics Supply Chain Visibility and Event Management

8 Warehouse Management Systems Manages warehouse inventory, space, equipment, and labor resources to direct the flow of materials and information from receiving and putaway to light assembly, order picking, value-added processing and shipment

9 WMS History 1975: First WMS installed at J. C. Penney. 1986: First WMS installation in C on a UNIX platform. 1990s: Hundreds of new stock locator & WMS systems; Windows NT platform emerges. 1995: MHIA WMS product section formed. 1999: First WMS company reaches annual revenues of $100 million. 2000: Expanded suites with TMS & SCV. Today: User-configurability & scalability remain key differentiators.

38 Creating a Responsive WMS Use contemporary ADC technology and systems to assure Accurate execution of receiving, storage, and move tasks Error-free picking, replenishment, and shipping Traceability Provide seamless interfaces to other corporate systems to assure Real-time visibility of inventory availability by SKU, quantity, lot number, serial number and shelf life by location Real-time order confirmation and status for customers Event-driven exception handling Facilitate a quick match of available resources to current and expected inbound, replenishment, and outbound workload Select the best operators and equipment for tasks based upon proximity, skill sets and priority Task operators to immediately store or cross-dock receipts

39 Creating a Responsive WMS Support returns processing and reverse logistics Use task interleaving to minimize deadheading Improve order consolidation, wave planning, inventory allocation, and pick sequencing Identify consolidation opportunities to free space and reduce outside storage requirements Support bill of material, work order, and value-added processing Update inventory records as events occur Provide accuracy that allows replacement of full physicals with scheduled cycle counts Time stamp each transaction and identify the operator who performed it Provide feedback to the workforce and support performance measurement Measure supplier and carrier performance

40 WMS Trends Further industry consolidation as well as alliances with enterprise systems providers Activity based costing and management Embedded profiling tools for space use analysis to facilitate relayout and inventory slotting Object-oriented tool kits for requirements modeling and WMS development
