Uncertainty during production processes has an important influence on the product quality as well as production costs. For multilevel process chains with serially connected processes, additional uncertainty can be caused by the previous step. The manufacturing of precision holes by drilling and reaming is an important multilevel process chain. The interactions between machine, tool and pre-drilled hole cause process errors during the quality determinant final reaming process. In this paper, a systematic approach for the identification and control of uncertainty during the reaming process is presented. Thus, the influence of key aspects like skewness of pre-drilled hole or the influences of material strength gradients are analyzed. Further, simulation models for the consideration of these uncertainties are presented.

Business decisions, transport organizations are guide by the principles of maximizing economic efficiency, reducing costs, and corporate social responsibility. Nevertheless, in the production and economic activities of transport enterprises, there are non-productive costs associated with their environmental activities: payment for excess and permissible pollution, costs of eliminating the consequences, accumulated damage, etc. To minimize this type of costs, it is propose to build a model of the activity of transport organizations from the standpoint of a systematic approach, which includes production processes, elements of production processes, management functions, and components of transport impact and aspects of corporate and social liability. The developed model can find its application in planning organizational and technical measures during their formation. The article presents information on unproductive excess costs of the transport industry of the Russian Federation in the period 2013-2016 y.o. The components of transport impact in transport organizations are considered. A model of production and economic activity of transport organizations from the standpoint of a systematic approach is proposed.
