Abstract

Manufacturing process selection is a process of determining the most appropriate process to fabricated the automotive door panel. The early consideration of manufacturing process in the product development is important in concurrent engineering to achieve a reduction in product development time, production cost, and quality defects. However, there are several factors involved in the step of selection manufacturing process such as the desired properties, size and shape of resultant composites, processing characteristic of raw material, the production speed and the manufacturing cost need the consideration. This study focuses to select the suitable manufacturing process for natural fiber composite of the door panel by compute the process selection according to the product design specification. Determining the right manufacturing process was performed based on fuzzy analytic hierarchy process (FAHP) with extent analysis and analytic hierarchy process concepts. The AHP and FAHP with extent analysis can be obtained from crisp number and triangular fuzzy comparison matrix, meanwhile, the extent analysis in this method is referred to the consideration of the extent to which an object satisfies the objective. The results show that Injection Molding is the best selection of manufacturing process, as in AHP and FAHP with extent analysis method, to fabricated automotive door panel by considering all the criteria and sub-criteria. Lastly, the result from both methods were compared and it is showed that the similar priority ranking in AHP and FAHP with extent analysis data.
