Abstract: This study is dedicated to the influence of fixation principle on the quality of working process of the “Side-by-side” linear installations for milking of goats. It was carried out an experimental assessment of the influence on the two fixation principles: “Principle of arbitrary fixation” and “Principle of arranged fixation”. The following evaluating indicators were used for the assessment of the influence: “Duration of one milking cycle”; “Relative value of the preparatory technological operations”; “Relative value of the terminative technological operations” and “Output per hour of operational working time”. The study was carried out by using of the ANOVA method. It has been found that the fixation principle causes significant influence for all of the evaluating indicators. The influence of the fixation principle on the indicator “Relative value of the preparatory technological operations” was the most expressed. On the second place was the influence on the “Output per hour of operational working time” indicator. The least expressed was the influence on the indicator “Relative value of the terminative technological operations”. The results of the study confirm the truth of the working hypothesis that the fixation principle affect significantly on the quality of working process of the “Side-by-side” linear installations for milking of goats. In compare with the “Principle of arbitrary fixation” the “Principle of arranged fixation” has a significant positive impact on the selected evaluative indicators.
