Probabilistic models of the processes researching of analytical materials preparation

General schemes of processes for information and analytical materials (IAM) preparing were described. Functional and network probabilistic models were developed for the analysis of typical technological schemes for the production of IAM in computer centers built on the basis of local computer networks. Based on the theory of random processes, a mathematical apparatus was developed for the analytical research of probabilistic network models for analyzing the time characteristics of IAM preparation processes. Functional equations and calculated relationships wereobtained that make it possible to conduct a multivariate analysis of various document preparation schemes and identify bottlenecks in the main standard technologies for preparing IAM.
