Systems and operations management - Assignment Example The company employs more than 52,000 employees based in four countries at sixteen different sites. The four countries in which the 16 sites are set up are Germany, France, the United Kingdom and Spain. The final assembly of the aircraft is done in Toulouse (France). Also, the company has its subsidiaries in the United States, Japan, China and India. The company has built the world first commercially viable fly-by-wire airliner, the Airbus A320, and also the largest airliner, the A380. The Airbus A380 is a four engine double deck airplane is a double-deck, and is the largest airplane in the world. It took its first flight on 27 April 2005 from Toulouse, and the first commercial flight was operated on 25 October 2007 from Singapore to Sydney in alliance with the Singapore Airlines Corporation. The airplane design offers cabin size of 50% more than the Boeing 747 which is the second largest airplane in the world and provides for a seating space of 850 people as compared to only 525 in t he Boeing 727. Airbus 380 is available in both the passenger and freight models and is the first airplane to use the GTL-based fuel technology. This paper, divided into four section, will make a detailed study about the operations management of Airbus 380, use of Information technology, and soft system methodology to enhance the business and management operations of Airbus. SECTION 1 This section will study the role of operations management, the reasons behind its initiation at the company, and its effect on the business objectives. This section provides the detailed analysis of operations management at Airbus, and how it has been implemented with the help of various OM techniques to increase efficiency. The previous operations at Airbus were not in line with the new requirements of Airbus A380. The new system required higher efficiencies, with precision, and reliability of speedy data and decision making. The old manufacturing facilities were not able to support the requirements of a new and more complex engineering product. It was important that the management makes significant changes in the operational process and data handling system to improve efficiencies. Also the supply chain of the company was in dire need of modifications and up gradations to carry out all the requirements for the manufacture of airbus A380. The engineers were not able to identify the cause of frequent disruptions that usually occurred in the system, which resulted in fault decision making at most of the times. In order to cure the system of these problems, it was evident that operational management would be employed in the form of various techniques that would assist in managing the overall business in a more profitable manner. The company management decided to implement two operations management techniques in its manufacturing floors – Enterprise resource planning and SCOR. Airbus introduced a new oracle based ERP system which also consisted of integrated accounting and cos ting along with the regular purchase and inventory management, production planning, and logistics management systems. The implementation of the ERP made it mandatory that the system is centralized in nature required and the production chain assumes a â€Å"Pull type† formation instead of the existing â€Å"Push type† configuration, ( Chekland, 1981). With these two reforms in place, it became easier to share the data easily within the various manufacturing centers of Airbus and

Named data networking - Term Paper Example Named data networking is a new architecture that has been developed to revolutionize the current internet architecture. There is no doubt the network engineers have made significant development in the current network design. Indeed, current networks have many innovations that have transformed how data are shared between various computers connected to the internet. Despite these, the same network is characterized by many challenges that have hindered the transfer of data between different endpoints. However, the named data networking is a paradigm that is poised to overcome the many challenges facing current implementation of networks. The introduction of named data networking will give more emphasis on data, liberate content from providers and provide a myriad of benefits to computer users, despite having some limitations. How named data network works The development of the named data networking is based on a number of concepts that work to improve how data is shared across the inter net. These concepts shape the function of any named data network based on the principle of named data networking. In a named data networking, each piece of data has a name, which uniquely identifies the data anywhere in the network configuration. In addition, all pieces of data provide more information on what they contain rather than what they are. The change from who to what is a significant shift that defines how named data networks function (Chen, Goes, & Marsden 154). ... This is a process where data are signed with unique signature name that also secure the metadata. The specific signatures are public keys with binding enforced between names and data. Because of this, a named data network does not need a name lookup process. Named data networks also have encryption mechanism that secures packets during transit from one location to another. Naming principles are a core function that influences the functioning of named data network. In a named data network, variable length identifiers are used to name data thus categorizing them into hierarchies. Content versions and segments are used to characterize information at the lower levels of a named data network (Serpanos and Wolf 23). When in use, the named data network works by specifying how information can traverse the network. The selection process is done when a host sends an interest group. The transport strategy in named data networks entails sending of single data packets in response to each interest packet received. In some instances, network hosts can send many interest packets to ensure that flow of data is controlled in some applications. With the difficulty of flow control, network nodes learn the best strategy to send their packets to support an end-to-end communication. Content segments are also used to replace TCP sequence numbers in use. Named data networks have different routing mechanism. A named data network makes use of a mechanism that provides link advertisement between various nodes. This advertisement provides includes a named prefix. Similarly, OSPF protocols can be used to achieve intra-domain routing that includes type-label values that indicated in the protocol segment. The use of names removes the challenge of using IP architecture for routing
