| Summary: | 碩士 === 南台科技大學 === 工業管理研究所 === 98 === For production management and marketing of general enterprises, inventory is very important. Too many inventories will cause the problem of stand-by of the fund. However, insufficient inventories will cause the running off of the customer and damage of goodwill. Therefore, reducing of the inventory and unlikely to influence the business become the importance goals of enterprises. To draft effective inventory management policies, not only can reduce the cost of inventory but also can offer the necessary supplies of goods to make improvement of customer satisfaction, and increase competitiveness in the market.
This thesis studies how to draft the inventory model of the minimum cost under situations of normal distribution and unknown demand. By introduction of numerical analysis, we investigate the inventory model under above two situations. We solve the inventory problems to minimize the total cost with optimal parameters through the differential way and find the best inventory parameters and minimum cost. We also verify the found models to make the optimal inventory model with minimum cost become more practical for future study and industry application.
