| PT. Global Metal Technology was a company engaging in manufacturing moldings products. The three main products of PT. Global Metal Technology were mandrel, insert cup, and bottle mold. PT. Global Metal Technology had plans to re-layout or re-arrange the current production floor layout. It happened because the company believed the necessity to adjust the layout with the current production activities. Since the beginning, the placement of the machines based solely on the similarity of machine types or referred as process-layout type.For the current layout, the frequency of material movement between machines occured was not proportional to the distance. It happened because the movement of material between machines that had high frequency traveled with a long distance. Thus resulted in the increment of total distance during production activities. Therefore, the purpose of this research is to analyze the current layout and to provide a layout that could give smaller total distance on material movement, and to compare it to the existing layout. This researchis using group-technology and modular method to achieve the proposed layout. Group-technology grouped machines based on part-family, while the modular-method grouped machines based on the similarity of production sequences. Both methods were integrated with ABSMODEL 3 algorithm to minimize the material handling cost and the total distance that occured in the proposed-layout. This research resulted in modular method chosen as the proposed production floor layout. The proposed layout gave the smallest total distance, which was 518.33 meters, and reduced the number machines used. |
