Currently, it is used as constant from interval zero one. Purpose article: Considering different offer transport individual European Union (EU) countries, can be assumed that coefficient should have values because there varying level non-zero probability vehicle will load. This study therefore proposes new approach value this direction. The aims identify clusters EU for common set. Methods: Analysis Variance (ANOVA) test was verify assumption differences among means offers. Cluster analysis aforementioned groups countries. real data offers Slovakia 18 Findings & added: results other countries if significant exist reasonable conclusion valid demonstrated more appropriate with various values, dependent For companies, implementation obtained practice beneficial increase their competitiveness through precise setting prices, but optimisation price itself regard expected costs.
