摘要

The design of a simple production line in which serially arranged workers can work independently of one another assuming inventory is presented. Traditional thought indicates that the output of such a line is determined by the slowest station. Traditional thought maintains that a balanced line is best, Goldratt (1984) says that a balanced line is inefficient because of statistical fluctuations and dependent resources. The present study presents a simulation of a 10-station line in which the capacity of station 10 is held constant while additional capacity is gradually added to stations 1-9. Station 10 is thus called the constraint, while stations 1-9 are non-constraints. The shape of the extra (or protective) capacity at non-constraints was varied from a flat pattern to patterns that increased from 1 to 9 and decreased from 1 to 9. Four random patterns were also tested. It was found that increasing non-constraint capacity increased the output of the line, and that the flat protective capacity pattern slightly bettered the performance of the other patterns.
