Influence of Vehicle Procurement on the Vehicle Fleet Energy Efficiency

“…(McDaniel et al, 2009) emphasize the vehicles compatibility, reliability, fuel efficiency, environmental level of the vehicle, warranty, procurement costs determined by state cont rac ts, veh icle l i fet i me, relationship with vehicle manufacturer (does the manufacturer provide good customer support), development and availability of sales network and the value of the used vehicles. (Vujanović et al, 2010) state that managers should take into consideration the criterion "adaptability of the vehicle's cargo space to transport requirements" in order to increase the utilization of the vehicles useful load capacity, which increasing the vehicle fleet energy efficiency.…”

“…In order to maximize their profit, the companies aim to realize all planned transport tasks during observed period, with lowest total transport and maintenance costs. To achieve the defined goal, the managers in the observed companies are trying to increase the energy efficiency of the vehicle fleet (Vujanović et al, 2010). One way to increase energy efficiency is the application of integrated fleet maintenance management (Vujanović et al, 2017).…”

Economical driving in the function of increasing the efficency of road transport companies

“…Različitim merama se utiče na proizvođače drumskih vozila da proizvode energetski efikasnija vozila, sa manjom emisijom izduvnih gasova. Istovremeno, postoje pokušaji da se deluje u oblasti upravljanja radom voznih parkova (za javne i za sopstvene potrebe) kako bi bili energetski efikasniji [2].…”

“…Konkretno, u polju B, dobijaju se podaci o uštedi goriva po vozilu/voznom parku, uštedi novca po vozilu/voznom parku (shodno uštedi u potrošnji goriva), kao i emisiji CO2 koja će biti eliminisana za posmatrani period po vozilu/voznom parku. Za izračunavanje podataka o emisiji CO2 za dizel motore 1 koristi se formula (2): CO2 = 26,66 x prosečna potrošnja goriva (g/km) (2) U polju C dobijaju se podaci koji su iz ugla kompanije možda i najbitniji, a tiču se broja pređenih kilometara, odnosno broja meseci nakon kojih će kompanija povratiti novac uložen u obuku vozača. U te svrhe za izračunavanje broja kilometara nakon kojih če kompanija povratiti uloženi novac koristi se formula (3):…”

Assessment of the overall effectiveness of the transport process

“…Istovremeno, postoje pokušaji da se deluje u oblasti upravljanja radom voznih parkova (za javne i za sopstvene potrebe) kako bi bili energetski efikasniji [7]. Održivi razvoj, između ostalog, podrazumeva i razvoj metoda za merenje ukupne efektivnosti transportnog procesa, odnosno efektivnosti drumskih vozila, vozača i kvaliteta pružene usluge što je i predmet ovog rada.…”
