When the inventory is too much, it will result in a backlog of funds, inventory expired, inventory damaged, and inventory storage costs increase. However, when the inventory is too little, it may cause out of stock, so that the factory production is interrupted or products cannot be delivered on time. The Ministry of Interior (MOI) of Taiwan amended the public hazardous substances and flammable pressurized gases establishment standards and safety control regulations on May 2nd, 2016. In this amendment, the range of the public hazardous substances has been expanded to include a new item, the combustible liquid, whose flash point is between 200 degree and 250 degree. However, the storage capacity of the public hazardous materials warehouse of the chemical company E, is limited. In order to comply with this new regulation, the chemical company E cannot store the new combustible liquid chemicals in its own warehouse when the quantity of the chemicals is greater than the storage capacity of the own warehouse. But building a new own warehouse or expanding the existing warehouse capacity is not in time from the aspect of the current operations. The study formulates the mathematical model and algorithm to determine the appropriate replenishment time and replenishment quantity for public hazardous material. At the same time, the model can manage the storage quantity in the own warehouse and rented warehouse to meet the chemical company E production requirements, and also compliance with the relevant law and regulation to minimize the total cost of the planning periods. Then, this study provides an effective assessment method to analyze the demand of the rented warehouse and economic benefits for public hazardous material under the conditions of the two suppliers and two warehouses.
