APPLICATION OF LEAN MANUFACTURING USING SIMULATION
Keywords:
Simulation, lean manufacturing, value stream mapping, WITNESS, case study.Abstract
This study involves the use of simulation to improve the efficiency of the production line. The simulation model imitates a real production system so that improvement alternatives can be evaluated without disrupting actual production. The production process at an automotive components manufacturing is used as a case study. A value stream mapping is constructed to portray the system flow. A simulation based on the current value stream mapping (VSM) data of the production line is built using the WITNESS simulation software. Four alternative solutions are proposed to increase the productivity of the production line: (1) eliminating the idle machine; (2) reducing the number of operators at selected machine; and (3) combination of alternative (1) and (2). Analysis results show the capability of these tools to formulate effective solutions for the case study system.References
