Regression Analysis and Modeling of the Efficiency of Construction and Installation Works in the Conditions of the North

Abstract

The article is discussed the selection and assessment of factors which gives the impact on effectiveness of construction and installation works in the northern regions. Special emphasis is given to development of planning matrix for the selection of factors and the selection of the most significant factors determined by the method of expert assessments. Based on the results of the study, definitions were given for the most significant factors, taking into account their ranking in accordance with the unified rating scale adopted to bring qualitative and quantitative assessments into one measurement scale. Based on the generalized data of expert assessments on the selected factors influence on the productivity of construction and installation works in the northern regions of Russia (as the main indicator of works efficiency), the multiple regression equation was developed, and there was made an assessment of the ability to predict work productivity based on specific conditions.
