Abstract: This paper investigates the benefits of deliberately unbalancing operation time means for non-automated production lines. The lines were simulated under the steady state condition, with various line lengths, buffer storage sizes, degrees of imbalance and patterns of imbalance. Output data were analysed using a set of statistical methods resulting in various conclusions being made. It was found that the best configurations are a bowl arrangement and a monotone decreasing order, with the first resulting in lower idle times and the second leading to lower average buffer levels than those of a balanced line.

Keywords: unpaced production lines; asynchronous; serial production line; coefficient of variation imbalance; service time means; simulation; efficiency; bowl arrangement; monotone decreasing order; idle times; average buffer levels. (search for similar items in EconPapers)
