%0 Journal Article %T A MATHEMATICAL MODEL FOR PROCESS CYCLE TIME - THEORY AND CASE STUDY %A FILIP TO£¿ENOVSKY %J Quality Innovation Prosperity %D 2010 %I Technical University of Kosice %X The article focuses on derivation of a regression model which describes dependence of process cycle time on relevant factors entering the process. The analyzed processes are typical in that the coefficient of variation of times corresponding to a given level of influential factors remains stable if the level of the factors change. The derived model is subsequently applied to real industrial data which show that such a model is suitable for the description of relations.
