Gembira Houseware is a retail corporation which sells housewares in seven stores across Gorontalo. Gembira Houseware stores its goods in a central warehouse which serves as a distribution center for all the stores. The management feels that the capacity of the current warehouse will not be sufficient for future purposes. Therefore, the management has bought a plot of land to build a new warehouse. Gembira Houseware desires a warehouse with better performance compared to the current warehouse. There are several problems related to utilization in the usage of the storage area in the current warehouse. After analyzing the symptom using cause and effect diagram, several root causes are discovered, namely: small aisle size, multilevel storage area design, storage area needs doesn’t match with the projected demand, and the lack of goods allocation policy. These root causes will be the basis for designing the new storage area. Storage area design begins with the determination of its dimensions. This is done by modeling the real system using multi-level warehouse layout design resulting in a total storage area of 6,767.2 square meters. Goods allocation then determined by modeling the real system using quadratic assignment allocation model which uses association rules principle. A correlated assignment heuristic algorithm has been developed to speed up the process of determining goods allocation. The heuristic algorithm produced a storage area layout which has 5.35% better performance compared to the current storage area.
