矿井串联系统模糊可靠性理论的研究

矿井系统不仅具有随机性，而且同时也具有模糊性，在系统分析与设计过程中应同时考虑这两种不确定性因素的影响。文中提出了模糊故障、模糊功能、系统模糊运营状态和广义可靠度等概念，并在此基础上提出了求单元及串联系统的生产能力、营运费用、应急维修费用、修理时间和广义可靠度等指标的方法，建立了使系统平均生产能力最大的系统最优运营策略的数学模型。

STUDY OF FUZZY RELIABILITY THEORY OF MINE SERIES SYSTEM

The mine series system has not only randomness but also fuzziness. In system analysis and design process, these two non-determinative factors should be considered at the same time. The concepts of fuzzy trouble, fuzzy function, fuzzy operation state and generalized reliability are proposed. Based on which the methods for finding the production capacity, operation cost, emergency repair and maintenance cost, repair time and generalized reliability of a unit and series system are proposed. And mathematic model for determining optimal operation policy of system is also established.
