The case study company of Mahachai branch, an import for selling a forklift. The company has to pre-purchase during the year 2017-2018. The company experienced problems with more than 10 remaining forklifts per year, which causes losses. Due to the depreciation and maintenance cost which is more than 1,000,000 baht. From that, there has been reduced the purchasing budget from 165,000,000 to less than 120,000,000 baths per year. For the above reason, the objective of this research is to find a purchasing policy in order to reduce the cost of remaining forklift, by applying the inventory model called Newsvendor in order to find the order quantity that provides the highest profit margin while consistent with the reduced purchase budget. Data analysis in the year 2017 to 2018, it was found that the monthly demand was normally distributed so it can calculate the Newsvendor order quantity and find the answer by using the suitable method under the limited budget. When applying the policies from the proposed model to the year 2018, found that the company would gain approximately 2,800,000 baht or 43.25% per year.
