The research team investiged and analyzed data related to the assembly process and detected errors in electronic circuit board manufacturing, work stations, movement øow, number of workers and real operating time of the machines during the production process. From that, calculate and determine the location of work stations, distance, area, space and build the overall plan of the system. The results of calculating the coordinates of the work stations using Lingo software are D (X1, Y1) = (10, 4)
E (X2, Y2) = (10, 3.99)
F (X3, Y3) = (9.99, 3.99) respectively. Based on the found coordinates, design and simulate the system using Tecnomatix Plant Simulation software. Simulation results using factory simulation show that the production rate on the assembly line increased by more than 11%. Comparing before and after the change, the added value is quite high at 71.6%. The initial input products of 400 products/day has increased to 440 products/day, including errors during the production process.
