Research on The Application of Caliper Assembly Line Improvement Based on Work Study

The heavy logistics, discrete operation floor, volume work in process, high-intensity operation and informal operational standards are taken as the production problems of digital caliper assembly in the G company. According to the problems mentioned above, the improvement scheme of caliper assembly line has been proposed based on work study. By Using 5W1H questioning technique, ECRS principle, stopwatch time study and Flexsim software simulation, the improving purposes combine bottleneck process improvement, the cycle time determination and assembly line layout adjustment. The results of alternative scheme shows that the equilibrium rate has increased to 81.62% compared with the original data 69.7%, the production cycle has been slashed 46.3s, production output has been increased by 169 and operational procedures become more standardized. These improvements can provide reference and guidance for digital caliper assembly production in the G company. The combination of business case study makes perfect sense to laboratory simulation experiments.
