520 _aThe main purpose of this study is to find a optimal solution for a specific formulation of the warehouse design by using SIMPLE++ simulation software for Thai Airways International Cargo Terminal. In This formulation, three types of cost are considered: costs associated construction and handling facilities costs, a shortage cost and storage policy Cost. The design configuration with eight rows, 26 columns and six stacker aisles are found the optimum in using three class-based assignment policy for this case. Furthermore, this study calculate the framework of the dual command continuous travel time model under class-based assignment. The model develop is for square in time system and the ABC dtribution is combined into the mode as the inventory turnover function. The evaluation of the continuous improvements of class-based assignment over random storage policy with various turnover functions are also calculated. On the comparison of the efficiency of the class-based assignment random assignment under dual command cycle, the percentage improvements grow as the number of class increases. The first class items occupy at least 25% of the storage rack is better to apply for a more general representation in the continuous warehouse model. Finally, it is concluded that a three class assignment policy is adequate for a highly skew inventory.
