Useful work coefficient. Useful work coefficient that maolum period insidecarreal work this is the time period to the ratio it is said.
N -the carexploitationmaking period,h-the car that's it period inside real timeExploitationperiod average use coefficient is equal to the following will be.

(1)
Ifcarhis ownmechanicresources full until it's over if it works,h-his durability D-showshein case

Calendared in mode working machines for
benefit size depends on:1)worker shiftsnumber; 2)empty time
(cardisorder,work of the discharge rhythm breakdown because of surface coming full not loading).One,two and three shift at work use coefficientbenefit =0.2; 0.4; 0.6being,yearly non-stop when workingbenefit=0.95  1 haequal to.Periodic, yesothein season working of cars use coefficient0.05 - 0.10up to pass goes.
Newmachines in creating meoplacedeterminer readiness coefficient as the most big readiness coefficient is taken. Technicianuse coefficient use in the process of the car by force stop stand up time sum in percent or unity in shares able to determine gives.Modern molding machines fortechnicaluse coefficient0.85 0.87around will be,this while this of cars level of repairability from low proof gives.
Consumertechnicaluse of the coefficient average if he knows the value,machines one year during average in how much time in good condition to be can determine.For example,if in the enterprise Ktf = 0.60has been50bench machinethere isif,this scorecarwork season during of them only average30one continuously performance possible means. Technicianuse coefficient of the car work ability coefficient like to interpretevenpossible,i.e. Ktf=0.60whencarto work that it is valid or car of time60%in works,the rest40%in whiletechnicalreasons because of does not work,that calculation possible.That's ittaohighlight should be, technicianuse of the coefficient the value of the car only reliability level not, perhapsto himtechnicalservice of showing especially the organization of repairs to be doneevenaffects.For example,the team and state in their households of cars of repairaggregatemethod current of them when donetechnicaluse coefficient much increase(in repaircarvoid standing up to reduce the length of stay)possible.
