The necessity of special automated systems creation for the effective organization of industrial enterprise processes is substantiated. The effectiveness indicators of the production planning process are defined and the criteria for their evaluation are determined. The results of an automated planning system introduction at several instrument-making enterprises are presented, according to which an improvement in all effectiveness indicators was obtained, namely: the number of mistakes in the data collection subprocess was reduced by 85%, the time of production plan creation was reduced to 1 minute, the mistakes of plan creation process were completely eliminated, the time of plan and it versions assessment was reduced by 60%, and the timing of the studied planning subprocesses was completely observed.

Analysis of production planning process was done: model of process described with applying of IDEF0 methodology, problems of production planning process listed and also risks of developed process identified. Risk assessment conducted by two methods – critical level ranking by experts and FMEA. Calculation results of Kendall coefficient of concordance and Spearmen criterion showed consistency of expert opinions and comparability of the level of assessed risks criticality. The most critical risks include risks related with mistakes in provided data and created plan and also risk of provided data unreliability. A key way of identified risks elimination is automating of studied process. After development of automated planning system and implementation of all methods for risks elimination or minimization, risk of wrong data entry into the system was assessed by HRA method.

The paper presents the experimental results of studies of the thermal conductivity and electrical conductivity of composite materials based on dimethylsiloxane SKTN A and carbon black filler. The percolation and their similarity in the processes of heat transfer and electrical conductivity are analyzed. The correspondence of experimentally observed percolation threshold values to theoretical descriptions is discussed.
