Abstract
The Company has a problem with inventory shortages caused by insufficient materials to meet customer needs and a lack of spare components for constructing finished goods due to the shared use of spare parts. To improve inventory management, this research employs engineering principles to create a new Material Requirement Planning (MRP). It also offers planners an option that would
provide an inventory that is more efficient than the current approach. The problem was analyzed with Cause and Effect (Fishbone Diagram), presented the structure of the Bill of Material (BOM), and used a spreadsheet program on the cloud (realtime) for material management Order Notification Program can be compatible with Microsoft Excel. This research uses ABC analysis of the high-order
Type A products of four departments. The reduction in raw material shortages from November to December 2022 resulted in a 100% reduction in delivery delays across all departments and a 66.67% reduction in the cost of warehouse management compared to the average ratio in the year 2022, leading to a cost savings of 64,180 baht
per year for warehouse management
