Implementation of Maynard Operation Sequence Technique in an Engine Manufacturing Industry: A Case Study
摘要
Maynard Operation Sequence Technique (MOST) is a predetermined motion time system that is used primarily in industrial settings to calculate the standard time in which a worker should perform a task. This technique breaks down the work into small, discrete elemental activities made up of various parameters and calculates the standard time for each activity from predetermined index data cards. MOST is a powerful analytical tool that helps increase productivity, improve methods, and facilitate planning. ABC Company produces tractor engines of various powers. But the demand for a 54 bhp engine is very high in the market. The company can assemble 70 engines in one shift, but demand varies at more than 78 engines. By implementing the MOST in the assembly shop, the standard time for the activities is calculated to be 66.31 min, whereas the actual existing average time is 71.37 min. After plotting a Pareto chart for all 128 elemental activities, it was found that there are some activities that are consuming more time because of excessive work content. After reducing these activities, the time for assembly was further reduced to 62.7 min. By achieving this standard time, 9030 man-hours will be saved annually, 10,800 US dollars. By doing so, the production will be increased from 70 to 75 engines.
