In current scenario the fashion industry (industry 4.O) needs to satisfy the various needs of customer in the aspect of quantity as well as quality of the products. In traditional methods the apparel industry used basic sewing machines for all operations with the help of man power so on that time to introduce different styles in the apparel is very difficult. In recent days the automation as well as improved techniques known as industrial engineering concepts is applicable in the field to improve productivity as well as quality to overcome the competitive market. Manufacturing of garment involves number of operations in different departments. In apparel sector to improve productivity as well as quality one must concentrate on machine, method, material and man. So the industrial engineering concepts will cover and manage the all above said factors and help to improve the productivity as well as quality of the products that will satisfies the consumer needs. This paper is going to discuss about the existing (manufacturing) methods in apparel units and help them to improve productivity by applying the one of recent techniques such as Capacity Study, Work study, Time study, Operator Performance, Follow-ups, Work-in-Progress and line balancing and they are already proven techniques to improve the productivity in different industries.

Person identification and authentication using the biological features of the person are designed and are in use all around the world. There are different types of biometric authentication system one such medium which is very new technique of the systems are vein pattern recognition system .This vein pattern recognition system can be designed using different algorithms. In this paper, the surveys of different algorithms which are implemented for vein pattern extraction are done.
