  • A decision support system for assembly line balancing problem 

    Authors:Ringim, İbrahim Uba
    Publisher and Date:(Kadir Has University, 2015)
    Assembly line balancing problems are generally considered to be complicated in real life. Like most complicated real life assembly line balancing problems obtaining a good solution is much easier than finding an optimal solution especially with big size problems. As a result, many heuristic approaches have been developed to find good optimal solutions to those problems. In this study, we develop a decision support system that solves a deterministic assembly line balancing problem using three ...
