Abstract. Rational experiment design properly chosen for studying complex processes makes it possible to reduce amount of experimental works and to simplify experimental data processing. Purpose of the work is to study main characteristics of different design types for choosing the most suitable one depending on the main determining condition of the experiment. Classification of designs for active experiment is presented in the article, as well as main properties of various designs and their key advantages and disadvantages. Criteria are determined for proper design choosing, and procedure of the design choosing is considered on the example of studies on the temperature normalization in the preparatory workings of the deep mines. Recommendations for applying different types of designs are presented depending on the given experimental conditions. Main conditions, which influence the choice of experiment design, include: degree of the phenomenon or process study, availability of material resources and time, as well as the researcher’s preferences.
Keywords: experimental design, full factorial experiment, fractional factorial experiment, composite designs, non-positional designs.
