decreased as the nunilDer of men in the loading crew increased. (See 

 Appendix D) . For example, the five-man crew will load a 190 crate truck 

 in 2.39 hours, while a six-man crew takes only 1.86 hours. Multiplying 

 the crew lahor time per load by the number of loads in the comple- 

 ment yields the total hours for loading. 



(3) Any crew-load complement must take less than 10 hours for 

 the round trip travel of the loading crew and for loading the number of 

 loads specified — this is the work day. The six man — two load comple- 

 ment has a 7.22 hour work day, the five man — two load complement 

 has an 8.28 hour work day, and four man — two load complement has 

 a 10.3 hour work day. This last complement must be rejected as im- 

 possible within the 10 hour day restriction — that is, not feasible. 



(4) The total quantity of labor time needed for each element of 

 the matrix in Figure 4 is determined. This includes travel time for fore- 

 man, pickup labor, and truck drivers, as well as time spent loading birds. 

 Total labor time consists of two elements: (a) the work day multiplied 

 by the crew size specified and (b) the travel time for the truck drivers. 

 Truck driver time enters these calculations in two ways: One driver is 

 always with the crew so the travel time for one truck driver and all 

 driver loading time is included when the length of work day is multi- 

 plied by the crew size. Travel time for all additional drivers is added to 

 get total man hours for loading and travel. 



The crew-load complements using the least amount of labor to 

 assemble the poultry are chosen from among those that are feasible. The 

 first step in this process is to determine the least labor use complement 

 in each column. In this case (Supply Band III), for those complements 

 which pick up only one load with one crew of men, the complement 

 which uses the least amount of labor time contains four men. For those 

 complements which pick up two loads with one crew of men, the com- 

 plement which uses the least amount of labor time contains five men, 

 and so on for the other columns. This same process of developing total 

 labor time and seeking the minimum labor use complement by columns 

 was repeated for the part load of 20 crates. 



Sets of crew-load complements sufficient to assemble the poultry 

 located in the band were then established. Assembly of these loads can 

 be accomplished with a numljer of different sets of complements as 

 shown in Table 3. Set B for instance is made up of two complements of 

 five men and two loads each plus one complement of four men and 1.05 

 loads. 



Total man hours for each of these sets of complements are shown 

 in Table 3. Sets A and B take 149.4 and 121.6 hours respectively. Sets 

 C, D, E, F, and G all take about 110 hours. However, Set H made up of 

 one complement of 9 men and 5.05 loads uses only 102.2 hours, and was 

 chosen as the least-cost Set. 



2. Travel and Loading Time 



Total labor use by crews of different sizes is a function of travel 

 time (which increases as the crew gets larger) and loading time (which 

 decreases as the crew gets larger) . The former remains fixed per man 

 regardless of the size of the crew.
