Layout Redesign Using Compiterized Relative Allocation of Facilities Techniques (CRAFT) Algorithm Method (Case Study: PCL Company)

Abstract

PCL Company is a Small -Medium Enterprises industry engaged in the printing sector in Indonesia. The PCL company's production floor's layout problem is crossing production lines. It can hinder workers from doing production, and the long-distance between machines creates an alternating current which causes time and energy to be wasted in moving materials. Workers are hampered and make long distances. This research aims to redesign the production layout to improve the production flow and minimize material handling distances in the production process in Printing. Data processing is carried out using (CRAFT). The CRAFT method is done by swapping areas in the initial layout to find a better solution based on the Activity Relationship Chart (ARC). The area exchange on the ARC will lead to a layout close to the minimum material handling distance. The result of the calculation of material handling for the prefix layout is 20,432 meters. Alternative Layout 1 has a material transfer distance of 5,849 meters, while alternative 2 has a material transfer distance of 7,095 meters. Alternative layout one was chosen as the best proposal because it has the smallest total material transfer distance. After that, the selected alternative proposed layout is used for the initial layout in the craft method processing. After processing the data using the CRAFT method, the optimal proposed layout is obtained.
