Warehouse Execution Systems (WES)〔Roberto Michel ("What Can Warehouse Execution Systems Do For Your Distribution Center Operations" ), Supply Chain 247〕〔James A. Cooke ("Warehouse execution systems: the answer for automated DCs?" )〕 are computerized systems used in distribution operations (Logistics) and are functionally equivalent to a manufacturing execution system or MES. Distribution operations are a form of a manufacturing operation that receive, store and track inbound material and then select and combine (assemble) various materials to form a finished product, order, or shipment. Features of both a WES and MES track and control work process. WES software organizes, sequences and synchronizes work resources necessary to complete the assembly and shipment of finished product. WES works in real time to enable the control of multiple elements of the production process (e.g. inputs, personnel, machines and support services) where changing conditions in one work process may require changing the directions of upstream or downstream processes (reactive). The WES is an intermediate step between an enterprise resource planning (ERP) system, warehouse management system WMS and the resources necessary to perform the various tasks. These resources include workers as well as process control systems. The WES communicates with resources to collect information and direct work effort. == Arguments against WES terminology == There are a number of voices in the material handling industry that disagree with the creation of a separate term to define WES functionality. "The new term being used by material handling software providers, integrators, and pretty much anyone associated with the warehousing industry is Warehouse Execution System (WES). According to a March article in DC Velocity, Warehouse Execution Systems can replace both the WMS and WCS by maintaining warehouse inventory records and driving the mechanization. It certainly seems like a very tasty fry sauce! What’s important to remember when exploring options for a Warehouse Execution System is that the functionality is the same functionality that has always been offered! The key to finding the best system for your facility is not a flashy new name offering a combination or best of both worlds mix of solutions, but rather a modularized solution that allows you to define the functionality required."〔Brian Reinhart ("Warehouse Execution Systems: A New Label for an Established Solution" )〕 "Why invent a new term? ... there is no such thing as a WES, WCS, or WMS. (There is) simply Warehouse Software functionality needed to suit a business requirement. If the term WES fits fine, but as soon as you draw too many boundaries you create is another layer of interface and support."〔Jay Morris ("Commenting on the Roberto Michel article" )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Warehouse execution system」の詳細全文を読む スポンサード リンク
