Abstract: The main role of lean production is to save money, produce production rate, and decrease all kinds of wastes [1]. Now a days all industries are trying to produce a good quality product, increases productivity so they are use lean tool and keep a float in market [2]. Single Piece Flow means that transporting parts during process from one step to next step is done without WORKIN-PROCESS (WIP) involved in between single piece or a small batch at a time [3]. The main purpose of Single

... e Flow is to improve effectiveness and increase productivity, shorter cycle time by eliminating waste and various lean methods [3] [4]. Line Balancing is essential in all the production lines but there are always some bottlenecks in theassembly line which results in a lot of wastages. Here, they discuss lean line balancing as a simple tool forthe improvement in the electronics assembly line [5]. This paper summarizes problems, models and algorithms on robust assembly line balancing and discusses further on research [6].
