Abstract

The case study is a company that manufactures and provides electrical installation services with production patterns under the customer's orders. From the cooperative internship, the project starts to explore the problem of parts storage. It was found that warehouse 4, which stores only parts for low-voltage switchgear cabinets, there is a mix of various types of parts, unused parts are collected from the previous projects, and limited storage space causes some products to be stored in random location or combined various product types. These problems have an effect to order picking process that operators cannot find parts. Therefore a fishbone diagram is used to analyze the cause of the problem and the ways to improve storage location are proposed by the theory of product grouping by ABC and FSN analysis. The new layouts of warehouse 4 are designed and also determine. The result of original and purpose layouts are compared with measuring the average total time of order picking process is 7.80 minutes per transaction and the average distance is 25.50 meters per transaction. For the original layouts for the new warehouse, by estimating result an average total time is 4.89 minutes per transaction and the average total distance is 23.45 meters per transaction. These results account for 37.31% reduced in time and for 8.03% reduced in distance.
