| Abstract | The main objective of this study is to propose new assembly lines for the Siam Automotive Industry Co., Ltd. First, investigation of existing assembly lines was made. All relevant data were collected directly and continuously along assembly lines. Then precedence diagrams were developed corresponding to work element times and precedence restrictions. Finally, optimal solutions could be achieved by applying COMSOAL technique and HOFFMAN technique with the aid of computer. Computer programs for both techniques were written in FORTRAN IV. A total of four separate lines namely Rear-Metal line, Cab-Metal line, Trim Line, and Chassis-Final line were investigated. The results of the study reveal that there are no significant deference's between the results achieved by both techniques. A set of production rate curves for each line was constructed in order to help management make decisions on the number of work stations required for a specified production rate. For cycle time of 405 seconds, using proposed assembly lines, the number of work stations could be reduced from 23 stations to 17 stations for Rear-Metal line, from 20 stations to 15 stations for Cab-Metal line, from 13 stations to 9 stations for Trim line, and from 27 stations to 19 stations for Chassis-Final line with approximately 28 percent reduction in unit labour cost for all lines. |
