Seaway is important for supply chain management in order to be carried for manufactured products and logistics activities. However, this logistics process does not only consist of transportation. Storing transported goods temporarily or permanently in ports according to an appropriate plan is vital in order to whole process is carried on properly. This paper describes the storage location assignment problem for outbound containers in a maritime terminal and hybrid sequence stacking algorithm (HSSA) which is used to solve this problem. In this problem; yard bay consists of 6 horizontally and 4 vertically units long (6x4) totally 24 units of squares. 18 containers which are come in random weight and sequence are wanted to be placed into these slots optimal. Considering the fact that ships are loaded first with the heaviest containers and then with lighter containers; the presence of lightweight containers in the upper spaces necessitates a rehandle operation for the lightweight containers above to reach heavy containers. The main purpose of our method is to minimize the number of rehandle operations. For this purpose, according to the basic logic of HSSA algorithm; the heaviest containers are tried to be placed on the top and leftmost slots, on the other hand the lightest containers are tried to be placed on the bottom and rightmost slots as much as possible. However, the fact that incoming containers come at different weights in a different number and in a previously unknown sequence is the biggest obstacle to this method always achieving the best solution. At this point, although the method is a heuristic algorithm, it is important that it gives satisfactory results. In this study, a sample was solved by using HSSA and the results were presented in the study. These results show that the proposed algorithm is effective and efficient in solving the storage location assignment problem.
