New approaches to specifying performance of construction machinery

Abstract

Izbor strojeva za različite građevinske radove mora se temeljiti na stvarnim uvjetima i postizanju njihove maksimalne učinkovitosti. Najvažniji parametar pri izboru građevinske mehanizacije jest specifikacija tih strojeva, koja ovisi o njihovoj primjeni u određenim uvjetima. Dosadašnja istraživanja pokazuju da izbor građevinskih strojeva ovisi o nizu varijabli čije su vrijednosti stohastičke prirode. Ovo istraživanje uspoređuje deterministički i stohastički pristup u specifikaciji tehničkih i planiranih učinaka građevinskih strojeva.The use of construction machinery for various construction processes must be based on the confrontation of actual conditions with the requirements for its maximum efficiency. The most important parameter for selecting construction machinery is its performance, which varies depending on its utilisation in specific conditions. Studies conducted so far show that the selection of construction machinery depends on a number of variables whose values are stochastic in nature. The present research aims at comparing the deterministic and stochastic approaches for the specification of technical and operational performance of construction machinery
