Warehouse Management Systems
The Warehouse Management System uses a database configured to support Warehouse Management System operations, containing detail describing a variety of standard Warehouse Management System elements including:
Individual stock keeping units (SKUs) that are handled and stored, e.g., weight, dimensions, case pack, automatic ID labels (bar codes, etc.), and inventory by location with manufacture date, lot code, etc. SKUs may include basic materials, fabricated parts, assemblies, and industrial and consumer finished goods, etc.;
Warehouse Management System storage locations, e.g., individual location number, picking sequence, type of use (picking, reserve storage, etc.), type of storage (each, case, pallet), location size or capacity, storage restriction (flammable, hazardous, high value materials, outdoor, etc.
Warehouse Management System Daily management functions include
Warehouse Management System Planning – finalizing the daily plan for receiving dock activity, selecting the workload/orders to be processed in the day or shift, (this may also be done by the business system), and calculating an estimate of the labor and vehicles required to pick and ship the orders to ensure the staffing is appropriate, and carriers are notified in time to meet the daily requirements.
Warehouse Management System Organizing – sequencing the orders to be picked. Organizing orders for picking can be accomplished in many ways, meeting the needs of the user. The primary objective is to be intentional, and not pick the orders in the sequence in which they were received unless the company wants to pay a carrier make sense for transportation and delivery. The initial way of organizing was called Wave Planning or Wave Picking, with two objectives, a. to minimize need for dock staging space, by having orders arrive at the shipping dock in trailer load sequence, and b. to create an order of flow that will support monitoring the progress through the day and eliminate/reduce last minute requests for overtime or delay of carrier departure.
Warehouse Management System Staffing – assign staff to work functions and areas, by Wave, to minimize staging Warehouse Management System .
Warehouse Management System Directing – ensuring the documented processes and procedures are embedded in the WMS and are consistently applied, used and appropriate for the nature of the work and service level intentions of the company (e.g., International Standards Organization 9000 (www.iso.org). This function may also be used to divide individual orders into logical work units and the ability to assign them to separate individuals for performance, consistent throughput requirements and physical layout, e.g., separating individual case picking from each unit picking, and individual pallet load picking, to improve productivity and supporting Control.
Controlling – providing milestones for management to monitor progress through the day, providing the opportunity to respond to problems in a timely way, and report data for performance analysis.
Warehouse Management System
Warehouse management systems support warehouse staff in performing the processes required to handle all of the major and many minor warehouse tasks such as receiving, inspection and acceptance, put-away, internal replenishment to picking positions, picking, packing, order assembly on the shipping dock, documentation, and shipping (loading onto carrier vehicles). A warehouse management system also helps in directing and validating each step, Warehouse Management System capturing and recording all inventory movement and status changes to the data file Warehouse Management System.
A warehouse management system usually represents the central unit in the software structure of a warehouse. The Warehouse management systems receives orders from the overlying host system, mostly an ERP system, manages these in a database and, after appropriate optimization, supplies them to the connected conveyor systems.
This becomes clear when you look at the processes necessary for E-Commerce: as soon as a customer places an order within an online shop, the information is passed along via the business host computer (mostly an ERP system) to the WMS. All necessary steps to manage this order, pick the ordered items etc. are then processed within the Warehouse management systems. Afterwards information is sent back to the business host computer to support financial transactions, advance shipping notifications to customers, inventory management, etc.
A modern Warehouse management systems will connect to a variety of communication technologies (radio frequency), automatic ID technologies (Bar code, RFID, etc.), mobile computers, and occasionally automated material handling (conveyors and sortation) and storage equipment Warehouse Management
System (carousels, automatic storage and retrieval, etc.).
