A spreadsheet tool from two linked modules based on MS Excel platform was constructed, merging different mathematical deterministic programming techniques. The first module utilizes linear program for least-cost ration formulation, aiming to obtain rough estimate what magnitude of the costs might be expected. Resulting value is then considered as target value of cost goal in the second module. It is based on weighted goal programming with penalty function. Obtained results confirm benefits of applied approach. It enables formulation of least-cost ration not taking too much risk of worsening the ration's nutritive value and balance between nutrients. This is especially important when improved economicand nutritive efficiency is the primal and common aim of optimization tool"},{"@xml:lang":"sl","#text":"Prispevek izpostavlja nekatere dejavnike, ki z vidika sestavljanja krmnih obrokov lahko izboljšajo gospodarnost živinoreje. V Excelovem okolju je bilo v obliki elektronskih preglednic razvito modularno orodje, ki združuje različne tehnike determinističnega matematičnega modeliranja. Prvi modul vključuje tehniko linearnega programiranja in služi za oceno najcenejšega monega krmnega obroka. Dobljeni rezultat kot ciljna vrednost vstopa v drugi modul, ki temelji na tehtanem ciljnem programiranju, nadgrajenem s kazensko funkcijo. Pridobljeni rezultati potrjujejo prednosti uporabljenega pristopa, ki omogoča sestavljanje najcenejših krmnih obrokov, ne da bi ob tem tvegali močnejše poslabšanje hranilne vrednosti in razmerja hranil.
