Upoređivanje tehničko-ekonoskih parametra mašina u različitim vrstamama biljne proizvodnje

The present study is a comprehensive survey covering the analysis of the development of the machine stock and the use of the machines of field crop producing, field vegetable growing and plantation cultivating farms by the application of the means of computer-guided modelling. The characteristics of the machines demanded by the production of different plants are taken into account and special attention is paid to the application of machines with reasonable capacity and technical level in respect of cost by different farm sizes. Our aim is to stipulate the range of farm size under which the development and operation of an own machine stock is not even with additional machine cost offering worth in the branches surveyed. By this the farm size limit under which the use of the logistically more defenceless lease work is reasonable in order to keep the cost of machine work at an acceptable rate will be defined. This limit varies from branch to branch. This way the fact that the mechanization of the individual branches is highly dependent from the farm size and the diversity of parameters effecting mechanization can be pointed out.Određivanje najefikasnijeg sastava mehanizacije za svaku farmu je vrlo značajno u današnje vreme. Neophodno je izraditi matematičke modele za planiranje sastava mehanizacije za male, sradnje i veće veličine farmi za ratarsku, povratarsku i vinogradrsku proizvodnje. Određivanje strukture i iskorišćenost mašina koje se može primeniti na farmama različite veličine, utiče na ekonomske informacije vezane uz mahanizaciju proizvodnje. Uzimajući u obzir sadašnju fragmentiranu strukturu farmi, postavljen je cilj da se odredi najefikasnija kombinacija mašina, koja bi se koristila različitim vrstamama biljne proizvodnje a različitim farmskim veličinama. Pored toga, pokušali smo da označimo tu farmsku veličinu u rataskoj, povratarskoj i vinogradrskoj proizvodnji ispod kojeg izgradnja spostvenog mašinskog sistema ekonomski nije opravdano
