Presentation and implementation multi-objective mathematical models to balance the assembly line

E. Shadkam; F. Ghavidel

Volume 10, Issue 1 , March 2021, , Pages 56-66

  The use of assembly lines is one of the important approaches in mass production of industrial products. Imbalance of assembly lines increases cycle time and idle times, resulting in reduced production rates, line efficiency, and increased system costs, which ultimately lead to low productivity. A hybrid ...  Read More
