| Summary: | 碩士 === 國立屏東科技大學 === 工業管理系所 === 103 === This research mainly focused on constructing a mathematical model for expected total profit of the Newsboy model with single cycle multi-product under the conditions of known price, quantity discount, space and budget constraints. In addition, the demand of each product is a random variable. The purpose of this paper is to find out the optimal purchase strategy to maximum the total expected profit using by expected marginal profit algorithm (called as EM algorithm) and numerical integration technique. Then, a sensitivity analysis was conducted for each parameter to understand the relationship between optimal purchase quantity and expected total profit, furthermore, a numerical example was provided to verify the feasibility of the proposed model. Finally, four conclusions were drawn for practical applications and future studies.
