In this study, two heuristic assembly line balancing techniques known as the "Ranked Positional Weight Technique", developed by Helgeson and Birnie, and the "Probabilistic Line Balancing Technique", developed by El-Sayed and Boucher, were applied to solve the problem of multi-model assembly line balancing in a clothing company for two models. Information about definitions and solution methods related to assembly line balancing problems is given. The aim of this article is the comparison of the efficiencies of two different procedures applied for the first time to solve line balancing in a clothing company. By using both methods, different restrictions are taken into consideration and two different line balancing results are reached. The balancing results are compared with each other.
