Abstract:
Nowadays, the plastic industry has a very high potential to grow up. So the plastic resins industry will be growing also. This thesis is conducted to design a new warehouse for Polymer Marketing and Trading Co., Ltd, the plastic resins trading company to cover 1000 tons per month sales expectation. At the beginning of this thesis, the theory of warehouse design and the characteristics of each plastics resins type were studied. Then the existing warehouse of a plastic resins trading company was studied as an example. And the requirements of warehouse design were studied and forecasted. The warehouse design started off with designing the operation procedure of the warehouse from receiving to shipping. Then the material handling equipments and material handling employees were designed. Lastly, the physical warehouse was designed. From the designed warehouse, the size inside the warehouse is 55 m. wide, 42.2 m. long, and 6 m. high. While, the size outside the warehouse is 57 m. wide and 39 m. long. The designed warehouse can cover the 1000 tons per month sales expectation and can store 2100 tons of plastic resins. From the warehouse validation by walking through the operational procedure design, it can be seen that the design is appropriate to the operation of the warehouse. The procedure of the operation can flow continuously without any obstacles. The material handling system and physical design can support the operational procedure design well. From cost evaluation, the cost per unit of the sales 1000 tons per month of using the designed warehouse is more than the cost of using the existing system. However, the designed warehouse can store 2100 tons of plastic resins. So the cost per unit of the inventory 2100 tons of using the designed warehouse is less than the cost of using the existing system. So the designed warehouse can be used for storing the plastic resins of the company in the future.
