Abstract

Remanufacturing is one of the initiatives to sustain the waste or used products or components .This study focuses on the assembly line in remanufacturing systems in the automotive industry that aims to establish strategies to improve efficiency and optimize the control process using the Taguchi method .This study was conducted to identify the current problem, such as the unsystematic assembly line process, unpredictable processing time, and uncertainties quality of the product. By using the Arena simulation, three proposed layout model was designed that generated the Taguchi parameter. Taguchi method was performed the analysis referred the condition of smaller is better by using the parameter of proposed layout model that contributes optimal condition out put in Level 3 with the value of S/N ratio is -37.02dB, validation of 5.63%, and mean for processing time and the number of station obtained of 73.00 and 84.33. The performance of the proposed layout model was analyzed using the simulation in Arena for running 20 hours with the arrival every 7 hours. In this result obtained, the simulation layout (3) is the optimal layout that increases the number of production which is the number of parts out generated from this layout model is 273 parts, the number of the part in is 819 parts, and the work in progress (WIP) is 510.74 parts. Based on the Taguchi method and Arena simulation result, the proposed layout 3 is the optimal condition layout. As an improvement of this study is to propose this layout can be applied to another industry, to propose the new idea by using the same attributes, applying to another analysis application, and the quality of product need to be considered due to uncertainties in term of material.
