Abstract

This project describes an approach, based on the Analytical Hierarchy Process (AHP) that assists decision makers or manufacturing engineers to determine the most appropriate remanufacturing process to be applied in the remanufacturing of crankshaft at the early stage of product remanufactured process. Remanufacturing can be defined as a process of restoring a non-functional, discarded, or traded in product to look and function like new condition, however the process of remanufacturing of crankshaft does not have a specific procedure and is inappropriate. It will make the manufacturing industry to incur more cost and increase time of remanufacturing the crankshaft. The best way to solve this problem is by developing a new process for remanufacturing of the crankshaft. As a result, the new process will give benefits to the manufacturers themselves in terms of income, but it has major benefits to the society as a whole. The selection of critical defects before remanufacturing a crankshaft was determined in this project. The factors influenced in the process selection of manufacturing process have been identified in order to fulfill the requirement of the remanufacturing. By using AHP as a decision making tool at an early stage of the product redevelopment process, the critical defect has been identified. AHP concept can assist remanufacturing engineers to evaluate and select the best remanufacturing process based on the various factors and sub-factors of a decision. The analysis has revealed that the most critical defect before remanufacturing a crankshaft is cracked with the highest percentage is 20.14%.
