Economic and Mathematic Modeling of Labour Efficiency

The article is dedicated to the author’s methodology of economic and mathematic modeling of labour efficiency indicators. Conditions and type of labour determine social and economic efficiency of labour, the increasing of which is becoming necessary for any organization. Economic and mathematic modeling makes it possible to calculate planned indicators of labour efficiency according to different parameters. The research suggests methods of building one-factor and multifactor statistic and dynamic economic and mathematical models of labour effectiveness indicators. The efficiency of labour of different categories of workers can be presented by two groups of indicators: indicators of production efficiency (labour efficiency) and indicators of economic (financial) efficiency (profitability of labour). On the basis of the analysis of the studied factors the dependence was derived which can be expressed in a deterministic or stochastic factor economic and mathematical model. Advantages of a stochastic model of efficiency of work consist is that incomplete, vague and insufficiently formalized information is also taken into account through a complex factorial function with variable structure and the changing nature of dynamics. The presented method allows a high degree of reliability in modeling planned increase in efficiency of labour. Thus, when evaluating and planning the efficiency of labour of the workers of commercial enterprises not only productivity but also profitability of labour should be taken into account.
