sembly matrix, such as 3c, are being handled. Each of these elements 

 is a separate supply band. 



(6) In each element on the diagonal in the matrix, all crew sizes 

 ranging from three to ten men in combination with each possible num- 

 ber of loads were tested to determine the crew size using the least 

 amount of labor time. This is the process of seeking dominance. For 

 instance, if four loads are to be assembled, it is possible to use the fol- 

 lowing load numbers in complements: four one-load complements, two 

 two-load complements, one four-load complement, and one one-load 

 complement with one three-load complement. Each complement requires 

 only one foreman. Smaller crew sizes generally exceeded the restriction 

 of a 10-hour work day, so they were rejected as not feasible. 



(7) Labor time involved in these computations included the travel 

 time and off time for pickup labor and foremen and the loading time for 

 pickup labor, foremen, and the driver of the truck being loaded. Travel 

 time is an "overhead" time element increasing in total with size of crew 

 and distance. Loading time is a "variable" time element decreasing in 

 total with size of crew and having no relation to distance.
