Study On The Reliability Of Nonel Detonation Network And Software Development For Reliability Evaluation

With the growing up of modern city, a demolishing means, which is higher efficient, lower expenses, safe and reliable, is widely used in city rebuilding, environment ameliorating, large quantities of infrastructure reconstruction and rebuilding. Designing a higher reliable network is the key to ensure a successful demolition. The thesis makes a study aiming at the reliability of nonel detonation network, which is widely used at present.The study concludes two main parts: one is reliability study of the nonel detonation network; the other is the design and the exploration of software of Reliability Evaluation for Nonel Detonation Network (RENDN for short).In the thesis, a structural diagram that can sum up general nonel network and can be conveniently disposed by computer. is brought forward after a thorough investigation on structure and characteristic of nonel detonation network. Using Fault Tree Analysis to analyze all the factors that can lead detonation network invalidation; According to the analysis methods of reliability for engineering system, Minimal Path-Structure Function (MP-SF for short), a method of calculating detonation network' reliability has been advanced, and it's advantages and calculation process are showed clearly in the paper. Author makes a study on the reliability of hangfire of network, and gives its' calculation methods. Using the theory of Fuzzy Evaluation comprehensively evaluation Nonel detonation network, deducing a fuzzy assessment model, with that can get subjection to classic network A. The author also gives evaluation grade, which contains A, B, C, D and E.Based on above study, RENDN software has been exploited with Visual Basic 6.0 and Object-Oriented Design on Windows XP platform. The software can automatically achieve explosive reliable degree calculation, time-lag simulation, and comprehensive evaluation of Nonel detonation network. After practical application, the results are verified that MP-SF method and the software are reliable and convenient.
