Abstract
The study aimed to examine the process of warehouse department in order to find error minimization methods and to reduce picking time for a general warehouse. The problem found was that there was no categorization for storage, resulting in waiting and the redundancy in picking process due to neither brand tags nor tastes adhering to shelves. Besides, unpatterned storage also caused picking errors. For the solution guidelines by cause analysis using a fishbone diagram, the researcher categorized types of products based on ABC Analysis to organize the warehouse layout in accordance with the theory of storage adjustment strategies. A flow process chart was brought to analyze the steps of picking process. The errors were fixed by using the theories of ECRS and visual control in order to improve operational methods for easier, to reduce the redundancy of operational time, and to minimize a chance of operational errors. Thus, the researcher studied related theories and used the tools for problem solving so that employees could pick products more quickly and more efficiently. The findings revealed 123 pre-improvement errors in October, November, and December 2022. It was found that there were 0 post-improvement error in January 2023. The findings were calculated as 100% in the delayed picking process due to the operational redundancy, resulting in the pre-improvement time for 85.2 minutes / 1 order form. The post-improvement time took 61 minutes / 1 order form, reduced by 28.4% on average.
