Assembly lines are traditionally arranged in a straight line, with tasks grouped into stations to maximize efficiency, a problem known as the assembly line balancing problem; however, the introduction of just-in-time production has highlighted advantages of arranging stations in a U‑line configuration over the traditional layout. The study proposes the branch and bound procedure ULINO to solve various U‑line assembly line balancing problems. ULINO is applied directly and within the framework of search methods. Experimental results show that ULINO procedures perform well and that the U‑line configuration frequently improves line efficiency compared to traditional lines.
AbstractTraditionally, assembly lines are arranged in a straight line. The design of such a line requires tasks to be grouped into stations such that the line efficiency is maximized. This problem is known as the assembly line balancing problem. However, as a consequence of introducing the just-in-time production principle, it has been recognized that arranging the stations in a U-line has several advantages over the traditional configuration. For solving different versions of the U-line assembly line balancing problem, we propose the branch and bound procedure ULINO which is applied directly and in the framework of search methods. Experimental results indicate that these procedures perform well and that the U-line configuration frequently improves the line efficiency compared to traditional lines.
