The article considers the methodology of statistical modeling of reliability of printing and packaging equipment. Here is given the principal form of dependence of the reliability function on the time of operation of equipment with 4 periods. For the purposes of constructing a function describing all periods of operation, the article suggests using the life-cycle of equipment operation (LCESL). Here is constructed a generalized analytical function of the failure rate, which describes the nuances of the change in the failure rate of real printing and packaging equipment. The developed failure rate functions allowed to simulate the change in the failure rate at the decommissioning stage for printing and packaging equipment put into operation in different years. The change in the intensity of failures, despite the different regimes of discounts, is associated with different technical conditions of the equipment and shops. The analysis of operational information and functions of failure rates shows that the printing equipment is suitable for work. Packaging equipment is obsolete and requires replacement. When decommissioning, the failure rate of the ‘Linepack’ sweets packer with one-shift operation mode and the chocolate line with a two-shift operating mode decreases almost equally. Such a change in the intensity of failure, despite the different modes of operation, is associated with various technical conditions and the loading of equipment. The constructed functions of failure rates for printing and packaging equipment made it possible to show the difference in the physical and normative life of the equipment. The constructed analytical function of reliability of printing and packaging equipment allows to conduct analysis, estimation and prediction of reliability, clarification of failures, standardization of reliability indicators. On the basis of the proposed methodology, an information base on the reliability of equipment can be created, and the task of synthesizing printing, packaging machines and systems can be solved on the basis. The failure rate function allows you to analyze statistics and causes of failures, develop measures to eliminate them, and evaluate the effectiveness of measures to ensure reliability.
