Automated storage and retrieval system (AS/RS) is a warehouse system that is gaining great attention today as it is a warehouse system that has a strong advantage in vertical space utilization that includes machines to store/retrieve products and rack with the same cells height. But nowadays, the warehouse does not always stored products with the same height. Thus, the traditional AS / RS systems may not be sufficient to meet several of customer’s demand and inefficient in space utilization due to the mismatch between the height of shelves and product. So, this research is interested to propose and compared the efficiency of a mini-load AS/RS with the rack of modular cells and mini-load AS / RS with the traditional rack systems by simulation of travel distance and time to storage/retrieve product of the S / R machine. The researcher collected the input data such as product data and dispatch of products from a case study warehouse that has different product sizes. The simulation results show that the AS/RS with the rack of modular cells can reduce the travel distance of the S / R machine by 424.58 meters or 3.89% and reduce the time to store/retrieve product by 242.37 seconds or 92.51% by compared with traditional warehouse and reduce the time to store/retrieve product 0.50 seconds or 2.48% by compared with the mini-load AS / RS with the traditional rack systems.
