Logistics automation is the application of computer software and / or automated machinery to improve the efficiency of logistics operations. Typically this refers to operations within a warehouse or distribution center, with broader tasks undertaken by supply chain management systems and enterprise resource planning systems. It has been suggested that this article or section be merged with Computer program. ...

Supply chain management (SCM) is the process of planning, implementing, and controlling the operations of the supply chain as efficiently as possible. ...
Enterprise Resource Planning systems (ERPs) integrate (or attempt to integrate) all data and processes of an organization into a unified system. ...
Logistics automation systems can powerfully complement the facilities provided by these higher level computer systems. The focus on an individual node within a wider logistics network allows systems to be highly tailored to the requirements of that node.
Components
Logistics automation systems comprise a variety of hardware and software components: - Fixed machinery
- Automated cranes (also called automated storage and retrieval systems): provide the ability to input and store a container of goods for later retrieval. Typically cranes serve a rack of locations, allowing many levels of stock to be stacked vertically, and allowing far high storage densities and better space utilisation than alternatives.
- Conveyors: automated conveyors allow the input of containers in one area of the warehouse, and either through hard coded rules or data input allow destination selection. The container will later appear at the selected destination.
- Sortation systems: similar to conveyors but typically have higher capacity and can divert containers more quickly. Typically used to distribute high volumes of small cartons to a large set of locations.
- Industrial Robots: four to six axis industrial robots, e.g. palletizing robots, are used for palletizing, depalletizing, packaging, comissioning and order picking.
- Typically all of these will automatically identify and track containers based upon barcodes, or increasingly, RFID tags
- Mobile technology
- Radio data terminals: these are hand held or truck mounted terminals which connect wirelessly to logistics automation software and provide instructions to operators moving throughout the warehouse. Many also have in-built barcode scanners to allow identification of containers.
- Software
- Integration software: this provides overall control of the automation machinery and for instance allows cranes to be connected up to conveyors for seamless stock movements.
- Operational control software: provides low-level decision making, such as where to store incoming containers, and where to retrieve them when requested.
- Business Control software: provides higher level functionality, such as identification of incoming deliveries / stock and scheduling order fulfilment, assignment of stock to outgoing trailers.

Benefits of logistics automation A typical warehouse or distribution center will receive stock of a variety of products from suppliers and store these until the receipt of orders from customers, whether individual buyers (e.g. mail order), retail branches (e.g. chain stores), or other companies (e.g. wholesalers). A logistics automation system may provide the following: Chain stores are a range of retail outlets which share a brand and central management, usually with standardised business methods and practices. ...
Wholesaling consists of the sale of goods/merchandise to retailers, to industrial, commercial, institutional, or other professional business users or to other wholesalers and related subordinated services. ...
- Automated goods in processes: Incoming goods can be marked with barcodes and the automation system notified of the expected stock. On arrival, the goods can be scanned and thereby identified, and taken via conveyors, sortation systems, and automated cranes into an automatically assigned storage location.
- Automated Goods Retrieval for Orders: On receipt of orders, the automation system is able to immediately locate goods and retrieve them to a pickface location.
- Automated despatch processing: Combining knowledge of all orders placed at the warehouse the automation system can assign picked goods into despatch units and then into outbound loads. Sortation systems and conveyors can then move these onto the outgoing trailers.
A complete warehouse automation system can drastically reduce the workforce required to run a facility, with human input required only for a few tasks, such as picking units of product from a bulk packed case. Even here, assistance can be provided with equipment such as pick-to-light units. Smaller systems may only be required to handle part of the process. Examples include automated storage and retrieval systems, which simply use cranes to store and retrieve identified cases or pallets, typically into a highbay storage system which would be unfeasible to access using fork-lift trucks or any other means. |
