Abstract

Mathematical and computer semi-Markov models of operational reliability management in complex recoverable gas-analytical systems of chemical pollution monitoring were developed. The models are distinguished by taking into account the structural redundancy and the process of transition of states of elements of the system (faultless operation, diagnostics, and repair) to ensure emergency recovery by maintenance using spare parts, tools, and accessories. The developed semi-Markov model enables one to solve the problems of optimal management of the operational reliability of a wide range of complex recoverable chemical engineering systems by emergency recovery during operation, specifically, by optimization of the list and size of spare parts, tools, and accessories for replacement of failed elements.

化学污染控制复杂气体分析系统中运行可靠性管理的计算机半马尔可夫模型

摘要

开发了化学污染监测复杂可回收气体分析系统中运行可靠性管理的数学和计算机半马尔可夫模型。模型的区分考虑了系统元素（无故障运行、诊断和修复）的结构冗余和状态转换过程，以确保通过使用备件、工具和附件进行维护的紧急恢复。开发的半马尔可夫模型使人们能够通过运行期间的紧急恢复，特别是通过优化备件、工具、工具的清单和大小，解决对各种复杂的可恢复化学工程系统的运行可靠性进行优化管理的问题。和用于更换故障元件的配件。
