The interactions between deviations of process variables can be flexibly represented in the new model 利用該模型,可以靈活地表達(dá)危險(xiǎn)和可操作性分析中的各種過程變量偏離之間的相互作用關(guān)系。
As an extension of the traditional signed digraph model , layered digraph models make hazard and operability analysis more thorough and systematic , which improves the capability of the expert system in identification of the potential safety hazards in the chemical processes 它拓展了傳統(tǒng)的有向圖模型,從而使危險(xiǎn)和可操作性分析的結(jié)果更全面、更系統(tǒng),提高了專家系統(tǒng)全面挖掘化工過程中潛在的安全危險(xiǎn)問題的能力。
To overcome the knowledge representation limitations of the traditional signed digraph model based expert systems for hazard and operability analysis , a novel layered digraph model for automating process hazard and operability analysis is proposed based on the graphical theory by decoupling the two dimensional signed digraph models in the three dimensional space 摘要為克服傳統(tǒng)的基于有向圖模型的危險(xiǎn)和可操作性分析專家系統(tǒng)在知識(shí)表達(dá)方面的局限性,通過將二維的有向圖模型在三維空間的解耦,采用圖論的方法,提出了一個(gè)可以用于危險(xiǎn)和可操作性分析自動(dòng)化的有向架模型。
