Abstract

Prilikom odabira modela planova pokusa, što je važna faza u većini znanstvenih istraživanja, potrebno je voditi računa o adekvatnosti modela, obliku rezultata koji se žele dobiti, te preciznosti modela odnosno pogrešci koja se nužno pojavljuje. Budući da se područje planova pokusa počelo razvijati, pa tako i uporabljati, u vrijeme kada je njihovom uporabom ostvarena velika ušteda u resursima, nije se dovoljno istražila mogućnost minimiziranja ostalih parametara eksperimentiranja kao što su cijena, utrošeno vrijeme i sl. Općenito se može reći da se vrlo malo istraživanja u literaturi odnosi na spomenuti problem. Istraživanje će se, u ovom radu, odnositi na razvoj metodologije i modela koji će biti potpora pri izboru i konačnom oblikovanju planova pokusa. Cilj je istražiti odnos pogreške pokusa odabranog modela (preciznost), troškova realizacije pokusa, te vremena potrebnog za eksperimentiranje. \Novorazvijeni model, koji predstavlja rezultat ovih istraživanja, trebao bi omogućiti pronalaženje optimalnih planova pokusa sa stajališta novouvedenih kriterija optimalnosti.

Abstract (english)

The process of choosing the experimental design is a significant phase in scientific researches. It is important to take into consideration the adequacy, the shape of results and the imprecision of the model as the side effect of error of estimation. In general, the result of using the design of experiments provides the significance benefits and cost saving. Due to limited resources like time, costs and complexity of design points realization we must take these facts in account when designing experiments. The scope of this research is to maximize the precision of model using multi-criteria approach. The study refers to research and development of the new model which will be a support in the design of experiments. The objective of study is to examine and understand the relation between prediction of variance (model precision), experiment costs, time expenditure. The new-developed model will provide a possibility of designing optimal experiments with respect to new added criteria.
