Abstract
The finished goods warehouse is one of the main factors to maximize production results as the final storage location before being shipped safely and on time. In this activity, there is still the use of the randomized storage method which causes a long warehousing time. In addition, there is a problem of obstructing the process of moving finished goods due to the discovery of backtracking and the lack of supporting warehousing facilities to reach the movement activities contained in the warehouse. This research aims to design an improved layout of the finished goods warehouse to increase the efficiency and effectiveness of the warehousing process time. This research uses promodel simulation and class-based storage method. The output variables measured are the total movement time from the production floor area to the shipping area and loading and uploading activities. The number of finished product variations to be simulated amounted to 40 variants. Building improvement scenarios are obtained from the results of warehouse layout improvements using the class-based storage method. Simulation in actual conditions obtained warehousing process time of 204.284 minutes. The proposed improvement scenarios are (1) Improvement of space requirements and storage area based on the percentage of movement frequency with a simulation time of 100.49 minutes- (2) The use of scenario 1 and equipped with additional supporting facilities in the form of material handling with a simulation time of 59.93 minutes. The second scenario was selected because it has a decrease in the percentage of warehousing time by 70.66%.
