Abstract
??
?????????????? In this research, warehouse management was carried out using the forecasting method of Chai Fah Kasetphan Company Limited. From site survey, they found a problem in the management of 9 chemical fertilizer brands, which has a sales value of more than 300 million baht per year. Therefore, historical sales data from January 2019 to December 2019 are used for 4 forecasting formulas and 2 formulas for improving the percentage weighted forecast value to compare the complete discrepancy value (MAD) with the actual sales results in January 2020 and a weighted percentage forecast improvement applied in February 2020. The results of the research revealed that the total gap of the actual sales forecast for January 2020 was -23,361 sacks. This indicates that, there are not enough chemical fertilizers for sale and no chemical fertilizer inventory. ??Therefore, the research has improved the forecast value by designing a weighted percentage to get a comparison gap (Gap) totaling 17,121 sacks. The results of this research can be used as good information for managing the company's inventory, Chaifah Kasetsart Co., Ltd.
