As Smart manufacturing increasing by laps and bond, Industrial automation gains its momentum, an increase in the number of “Smart” production machines has been never seen before. Reenergize a traditional distribution value chain, enabling mass customization and a real-time information exchange between buyers and manufacturers using IoT for drug asset management possible with the help of fog computing concept. Manufacturers are slowly beginning to transform their manufacturing facility into an integrated network of Cyber-Physical Systems, also known as "Smart Factory". Additionally, technological advances in the fields of Cloud Computing, Internet of Things, and Distributed Computers have also led to produce large amount of data. In contrast, small Manufacturing facilities often fall behind when it comes to merging downstream production facilities with Cloud due to a lack of IT infrastructure and associated costs. Besides, manufacturers are concerned about data privacy and integrity when they view Cloud Manufacturing as a means of distributing and exchanging data. In such cases Fog computing is a natural alternative of cloud computing, Fog computing characteristics, compression with cloud computing detail out clearly. For improving latency time various AI method of scheduling with their benefits compression table mentioned. Fog computing is a data platform that distributes data generated in the production environment intelligently by resources in various parts of the cloud network while promoting data privacy and ownership, using the Fog Computing paradigm
