MODELING AND FACTOR’S ANALYSIS OF INCOME TRAM-TROLLEYBUS ENTERPRISES
Abstract
Research of methods of influence crucial factors of changing income of tram-trolleybus enterprises was conducted. Multiplicative models that are required and contain technical and economic factors were determined. To asses the influence of each factor on the change of the revenue the use of phased factor analysis was suggested that is based on the index modification of the chain substitution method. The essence of such approach lays in the gradual conduction of analytical analysis of influence at first for example two factors, then three and so on. This allows in each case rather timely and precisely determine the influence on the revenue variation of the factors that at the moment are the most important from the production view.Keywords: modeling, factor’s analysis, income, factor, rolling-stock, run, regular of movement, index.
