Of the car profitability-Q his useful return-Horse maolum period inside spendRto the amount ratio according to is determined.
Q=
(3)
General in case spend amount consisting of the following finds:En- energyspending, Mt - materialand zagatovkas, In -instrument equipment,Tr-to operators pay a fee, Ob - technicianservice show,Rm- repair,Nk-sexes,cash registers andfactoryexpenses,Am-amortization spend:
R=En+In+Mt+Tr+Ob+Rm+Nk+Am(4)
Q-sizefrom 1big to be need,reflection in casecarto the detriment works and such of the car existence own loses its logic.
Economical effect. Carfrom working coming yearly effect(yearly benefit)
, (5)
this on the ground, Horse -yearly i'm back,amount/year; R-exploitative spend amount,amount/year
Cover term-Pearthe same service duration like is determined such economic effectcarfor the price equal to will be.
S=Pear  benefit.(Horse-R) Am(6)
This on the groundR-yearlyexploitationexpenses,
Yearly exploitative spend to the following equal to:
R=En+Mt+In+Tr+Ob+Nk
Cover term fordepreciationexpenses the following expression through is found:
(7)
this on the groundN is a carservice term,
(6)in the expression Amthevalue from putting after this expression to the following equal to will be.
(8)
Exploitative expenses coefficient. Exploitative expenses coefficient K that of the car whole work period during expenses of the amountcarat the cost of ratio we say:
(9)
Uin case(5)the equation the following in appearance to write possible:
(10)
Machine recognizedprice coefficient (carof the cost expenses to the amount relatively with interest ratio)
(11)
(9)from the expression apparently as it stands,exploitative expenses coefficient of the car away of endurance increase with together grow up goes andDof big in their values50-100 hareach possible.So,of expenses common in the amountcarof the cost share decreased goes.
