229. Definition. Logistics is the art of plannin and
carrying o m i t n r y movement , evacuction and supp1y.f Tagiatical
factors, as discussed in this chapter, are t!,ose factors
dealing with the most important phase of sup_nly -- the
comautation of requirements.
230. Types of ZoRistical Factors.
'a. There are three methods of expressing petro-
leum, oil, and lubricant logistical factors for coqmtation
of large soale renuirements:
(1) Pounds per man per day.
(2) Gallons per .mn per day.
(3) mpresslon of reouirements of HT-80 gasoline
by either of t%se first two methods,
and recluirements of allied products as
percentages of ?!T-80,
b. There is easentiallg no differenoe in either
of the three metbods of expressing petrolem, oil and lubricant
logistical faotora. The use of "Pounds per LW per
day"*is desirable whon requirements are to be stated in
tons, and ",qallons per luau per day:' (greases excepted) is
desirable when requirements are to be expressed in total
gallons or barrels.
231. Eethods of Determinatim. There are.two gener-
ally accepted methods of detsmining petroI.eun, oil and
lubricant logistical factors:
a. The vehicular raethod , in which the average
daily reauirenents of any unit or nimber or units can be
determined by computing from experience the average numScr
of niles to be traveled daily by all ~6hhleSinvolvod,
nultipljjing the average nunbar of miles to be travclcd by
the total number of each type vehicle involved, and crithar
multiplying tho result VJ the avornge oonmnn?tlon rate (increased
by safety faotora) in Gallons pormllo for each
type vehicle (taken from Ff 9-2600) , or dividing thb result
by the averace consum2tqon .rate in :lilca por .pallon for
each typo mhicle involvcd. Norr~~lly, the total requirements
of msoline for potmr oqulo"t, coolcinq, hoatinc,
lightina: and other miscellaneous needs arG figurcd nt twenty
porcont of the gasoline reouiromcnts for the vehicles. The
total figure can be dlvid6.d 5y the irlachine records unit
etrenRth or by tho ration strmqth to ohtdn the rcauironats
in eallons mr 3811pr day. O i l and lubricants aro rlso
normally dotomined as percentaces of t_otalfuLl rquirementa.
rcrccntagea usually used are: .,nqinc oil - 34'. of
total fuel rcouirmcnts; gaar oil - J$ of'total ruol requirements:
and grease - 1.5$ of total fuel roauirmonts.
