Application of Work Study in Lights Assembly Line Balance

Work study is a kind of important method to improve productivity,it includes method study and work measurement. Aiming at the production line of A101 rear light at a company,the paper applies to stopwatch test method of work measurement to measure work time of every station and find out bottle-neck stations. using man-machine work analysis of method study and the 5W1H check-list,the existing problems are analyzed. According to the principles of ECRS and the theory of production line balance,a new project of production line balance is designed. Implementation of this new project makes the rate of production line balance upgrade 11.4%,the productivity is improved immensely.
