Work Time Measurement Tool "Jobtan" Implementation Case 4 at Nakayo Factory

NX総合研究所
Nakaiyo Co., Ltd. has been involved in the manufacturing of communication equipment since its founding in 1944. In recent years, leveraging its unique communication technology, the company has launched a service called "Factory NYC (Nice)" that enables remote monitoring of manufacturing sites by connecting manufacturing equipment and sensors with IoT devices. At the Maebashi factory, the company previously manufactured products using a line production system, but switched to a cell production system to accommodate a variety of products in small lots. In the line production system, products were transported on a straight conveyor belt, which fixed the movement of workers, whereas the cell production system allows small teams to move and work within U-shaped or L-shaped layouts. To improve productivity at the Maebashi factory, the company has implemented "Mizusumashi," which supplies parts, handles changeovers, and addresses initial line troubles at each cell. The term "Mizusumashi" refers to an insect that quickly darts across water, symbolizing the movement between the parts warehouse and production cells. To understand how this "Mizusumashi" operates and to implement business improvements, the company introduced "Jobtan."
