RFID, bar code scanners, and mobile computers may be used for automatic identification, data capture, and transmission to a central data warehouse. WMS extended functionality may include pick-to-light and voice-directed picking systems to speed up order preparation and loading.
TMS and WMS also work with customer relationship management (CRM) and order management systems (OMS) for order fulfillment. Order fulfillment entails order placement, receipt, processing, preparation, loading, and delivery.
OMS processes consist of order entry, credit checks, inventory allocation, invoice generation, and fulfillment location. A distributed order management (DOM) system is extended OMS functionality. It is used to allocate orders across a network of production, distribution, and/or retail locations to optimize cost and service levels.
A CRM stores and manages current and prospective customers’ interactions with sales, marketing, customer service, and technical support; in a single location. CRM and OMS work together to ensure relevant, current customer requirements and information are used to minimize errors, rework, and returns.
Finally, reverse logistics can be used to process returns to minimize waste. The objective is to receive, sort, stage, and determine which returns can be sent to inventory. Other items may be repaired, refurbished, remanufactured, and repackaged for secondary markets.
