This was a study of a man controlled assembly operation with Poisson arrivals. The height for the work surface, relative to the seated operator, was varied for nine operators with production time, queue length, outgoing quality, and the distribution of service times being observed. The work surface height did not affect, significantly, any of the dependent variables. The general trend indicated that the optimal height in terms of production time and queue length seems to be the height with the elbow two inches above the work surface. Also, it was found that a significant interaction between work surface heights and subjects indicates that, in terms of quality, different subjects perform better at different heights. Subjects did have a significant affect on all these variables. Within the limits of this research, 98.1 percent of the 108 service time distributions were skewed positively and were more peaked than the normal distribution. In addition, there was a high positive correlation between skewness and kurtosis. Author
