Usulan Perancangan Ulang Tata Letak Lantai Produksi Menggunakan Metode Simulated Annealing dan Algoritma Corelap pada CV. Rosen Jaya

Abstract

CV. Rosen Jaya is a company operating in the wood-based furniture manufacturing sector. The furniture products produced by this company include chairs, door panels, and door frames. The company faces a common problem: failure to meet production targets within the time specified by customer demand. This issue is mainly caused by an inefficient production flow, which includes cross movement, backtracking, and by-passing, resulting in long-distance material handling. This problem can be addressed by improving the production floor layout using the Simulated Annealing Method and the CORELAP Algorithm. This study aims to design a production floor layout that minimizes distance and total material handling moment with a Line Efficiency Rate above 75%. The company’s current layout has a total material handling moment of 9246.34 m/month with a Line Efficiency Rate of 48.86%, which is considered inefficient as it does not meet the minimum threshold of 75%.The results of the study show that the Simulated Annealing Method reduces the total material handling moment to 8138.02 m/month, while the CORELAP Algorithm results in 8801.2 m/month. Based on the comparison between the current layout, Simulated Annealing Method, and CORELAP Algorithm, the best layout design is achieved using the Simulated Annealing Method, which results in the lowest total material handling moment and a Line Efficiency Rate of 84.4%, thus qualifying as an efficient layout. Furthermore, the issues of cross movement, backtracking, and by-passing can be effectively resolved.
