Nowadays, order-picking is frequently considered as one of the most laborious and time-consuming tasks in warehouse operations. The routing of an order picker is usually a vital part of the overall operating cost. Failure to overcome the order-picking process problem may cause the risk of a long time to collect the goods. Hence, finding the optimal route for an order picker may help the management process of a warehouse become more efficient. The mathematical approach that combined the multi-criteria decision-making method (MCDM) with the shortest route algorithm has not yet been proposed into the warehouse problem. Therefore, by using this integration method, the main objective of this study contributes to fill this research gap in finding the optimal route for the Chevron warehouse. The proposed method in this study integrates the Entropy method for calculating the weightage of criteria, the Simple Additive Weighting (SAW) method for finding the weightage of alternatives, and the shortest route algorithm called Weighted Floyd Warshall Algorithm (WFWA) to find the optimal route for an order picker of a warehouse. In addition, the problem is easily solved with the help of Toolkit for Oracle (TORA) software. The results show that the proposed integration method has successfully obtained the optimal route which is the best or shortest route for the order picker. © 2024 Author(s).
