DESIGN AND ANALYSIS OF SECURE DATA ENHANCEMENT IN A DIGITAL MANUFACTURING SYSTEM

Over the recent years, information technology is transferred from the usage of mainframe computer systems to client-server models, embedding new principles, concepts and techniques. It is currently known as cloud computing. The primary motivation for embarking on cloud computing, as advocated by computer science experts, encourages users to abandon the burden of computer hardware needs, time – sharing utility demands and network system needs. It is also used to embrace the utility of commercial grid systems, which guarantee to reduce overall client – side requirements and system complexity. While being attracted to cloud computing, it is realized that there are several unchartered risks and challenges introduced along with this relocation decision. Primarily, effectiveness of the traditional protection mechanisms is deteriorated. Despite the above shortcomings of cloud computing, the utilization and attraction of cloud computing are still expanding inwardly from general to manufacturing – based cloud computing. Cloud computing aids in the creation of intelligent factory networks and prominently in crafting the features of product life- cycle services such as product design, manufacturing, testing and management. In this manufacturing- propelled cloud computing system, the traditional operating paradigm of shop-floor control system exists and it consists of material requirement planning (MRP), enterprise resource planning (ERP), master production scheduling (MPS), reorder point system (RPS), sales and operations planning (S&OP) has been abandoned. Instead, a coordinated system has all these planning and operation modules embedded into it. It has evolved directly and indirectly. This niche concept is referred as Manufacturing Execution System.
