A new approach for mixed model assembly line balancing and worker assignment problem

In this study, an assembly line was considered which has workforce effect in addition to simple balancing problem. The problem which is defined as assembly line balancing and worker assignment problem, was tested two example problems and was applied a problem been in literature which has 58 operations. The problem was defined for an assembly line which has mixed model, deterministic operation times, known cycle time and multi skill workforce. Analytical approaches were investigated and the problems were solved by integer programming methods. For discovering behaviors of mathematical model were analyzed to scenario analysis under different conditions. Effect of cycle time length and workforce skill numbers were examined by scenario analysis.
