Warehouse execution system

Warehouse Execution Systems ( WES ) [1] [2] are computerized systems used in distribution operations ( Logistics ) and are functionally equivalent to a manufacturing execution system or MES. (Assembled). (1) (1) (1) (1) (1) (1) (1) (1) View Larger Map Manufacturers and Distributors

Features of both a WES and MES track and control work process. WES software organizes , sequences and synchronizes work resources necessary to complete assembly and shipment of finished product. WES works in real time to enable the control of multiple elements of the production process (eg inputs, personnel, machines and support services).

The WMS is an intermediate step between an enterprise resource planning (ERP) system, and warehouse management system . These resources include workers as well as process control systems. The WES communicates with resources to collect information and direct work effort.

WES Background

WES Emerged as a hybrid system combined That specific WMS functionality with warehouse control system (WCS) functionality for automated warehouses. WCS is the software that controls the movement of cases, boxes, totes or pallets on conveyor and sorting systems. WES adds business process logic to the almost real-time WCS data. Because WES is tightly integrated with automated systems such as conveyors, sorting, pick-to-light, etc., it has near real-time visibility into bottleneck issues.

WES also tends to be more “productized” than WCS – more WMS-type features are fully developed and often come standard. Vendors typically offer modular software solutions that together form a comprehensive WES. The modules cover WMS, conveyor control, advanced analytics / reporting, and integration functionalities. Typical WES packages contain a suite of best practice methods for warehouse operations – eg picking and packing – that users can configure based on a workflow. This product can be processed without customizing the product. [3]

Typical warehouse functionality such as replenishment and order picking take advantage of real-time conditions to optimize productivity. Whereas typical WMS functionality calls for planning and releasing orders to be picked, a WES is focused on executing these tasks based on existing facility conditions. As a result, warehouses become more flexible and agile in response.

The Purpose of WES

A WES has the ability to span across multiple areas of warehouse functionality that are traditionally managed by a variety of specialized software systems. WES can be deployed to encompass warehouse management functionality, warehouse control system functionality, material handling equipment (MHE) ERP systems. Encompassing this broad range of functionality is a distinct advantage for WES. As a result, the WES can leverage its visibility of lower level warehouse data to quickly adapt functionality for current conditions. This is especially true in facilities with automated systems. The WES can use its WCS roots to access connections to advanced picking and sorting systems thus offering an agile approach to optimizing operations in near real-time.

WES Business Intelligence Capabilities

Another benefit of this approach is the ability to provide unprecedented automated business intelligence . WES ‘access to and collection of data from various warehouses. The WES can feed data into ict business intelligence engine to be mined in near real-time so That DC operations can move beyond just being agile in response to changing circumstances, to being white proactive in making adjustments’ before changing requirements. WES data can be analyzed to identify trends and predict operational conditions. For example, WES feedback to ramp up staffing and equipment needs more efficiently to reduce overall costs. WES data can also be used to predict issues such as potential stock-outs or order fulfillment delays. Issue detection can also relate to preventative maintenance of warehouse equipment such as lift trucks, conveyor systems, etc. To illustrate this point, the WES can predict when a conveyor motor may need to be replaced or downtime. By collecting and analyzing data from various lower level warehouse points and taking proactive action,

Arguments against WES terminology

WES functionality. WES functionality. WES functionality.

“Warehouse Execution System (WES) is the most commonly used Warehouse Execution System (WES). The key to finding a way to make money is to make sure that you get the best out of your warehouse. The best system for your facility is not a flashy new name offering a combination or best of both worlds of solutions, but rather a modularized solution that allows you to define the functionality required. ” [4]

“WES, WCS, or WMS.” Warehouse Software is an industry-leading software company, You draw too many boundaries you create is another layer of interface and support. ” [5]

Counters to the arguments

Right or wrong to create a new term, the term WES is used in the material handling and distribution industry. The creation of the term arose as a “gap” was identified in the previous divisions of functionality required to operate a distribution facility. “As the demands of omni-channel distributions continue to be more efficient, many distributors are realizing that the current functionalities of WMS and WCS are insufficient to align, automate, and synchronize the necessary processes to optimally control their Order-fulfillment needs. ” [6]

A common occurrence in a broad distribution center is that there are multiple variants of large-scale equipment and work processes provided by multiple vendors. The control of These complex and intricate Sometimes functions is provided by the equipment control software is begging That Often called Expired warehouse control system or WCS software. WCS software packages running. Without a WES layer, it is possible to use the required facilities. This will require either a “Master WCS” or the WMS or ERP system to perform the function. A WES is the master WCS.

As in a MES Manufacturing Execution System the line between higher level and lower level control is blurred and not well defined, so it is with a WES. Manufacturing operations are more mature than distribution when considering lean practices. [7] This is evidenced by the total lack of a Wikipedia article on “Lean distribution”. Manufacturing operations in the production and distribution of chemicals. A special category of software was created for manufacturing to integrate the overall production and coordination of the efforts of all production resources.

WES and E-Commerce

One of the byproducts of the rise of e-commerce, is the need for software to support the complexities of omni-channel fulfillment. “The omni-channel environment places Enormous pressure is DCs to keep up with higher order volumes Including rapid processing of small e-commerce orders.” [3] The market for WES continuous solutions to grow as DC operators seek productivity and supporting a high throughput .

Emerging functionality such as waveless processing is drawing attention to WES. Waveless processing requires constantly taking care of the warehouse floor efficiently. This is in direct contrast to the typical WMS approach of batching the orders in waves. Waveless processing of the WES batch of near real-time information.
