Recently, medical device industry has been developing variously according to the development of medical technology. In 2016, the domestic medical device market grew 11.5% year-on-year to 5.8 trillion won, showing an annual average growth rate of 8.2%. The medical device industry is divided into dental field, imaging equipment field, and diagnostic field. In 2016, manufacturing performance has grown by 12.0% over the previous year to 5.6 trillion won. By sector, KRW 800 billion in dental implants, KRW 400 billion in ultrasound imaging diagnosis, and KRW 180 billion in biomaterials for tissue repair etc. In addition, the localization of medical devices, which have been dependent on imports, has been on an increasing trend every year. Competition among companies to enter the market is also intensifying. Under such circumstances, medical device manufacturers can not survive if they can not supply uniform quality products at a satisfactory price to customers based on human safety. Above all, it has become necessary to continuously improve the manufacturing process in order to reduce costs and improve quality. Therefore, in this study, we intend to find a way to introduce efficient conveyor system according to the work capacity and skill level of the worker to improve the manufacturing process of A company. increasing trend every year.
