IMPROVEMENT OF EXPERIMENTAL PLANS USING MULTI-CRITERIA APPROACH

The process of designing experimental plans is based on the choice of the number and placement of design points. The question which should be answered is how to choose the design points and number of replications to achieve a more precise model. Due to the limitation of research resources like time and costs of performing certain design points, it is necessary to take these constraints into account when designing experiments. The mentioned time consumption, cost and model precision are defined as new criteria. The scope of the research is to define the procedure of maximizing model precision using multi-criteria approach. The study refers to the research and development of a new procedure which will be a support in the process of improvement of experimental plans.
