The outdoor lighting environment was evaluated by using fuzzy mathematical model 摘要借助于模糊數(shù)學(xué)模型對居住區(qū)室外光環(huán)境的質(zhì)量進行評價。
Improvement and application of a fuzzy mathematical model for assessment of heavy metal pollution in soil 針對土壤重金屬污染評價的模糊數(shù)學(xué)模型的改進及應(yīng)用
In the process of the system study , the knowledge in the domain of ship collision avoidance is analyzed and the collision mechanism , process and the tactic are studied firstly . and then , using the fuzzy mathematics theory , the fuzzy mathematical model of judging collision risk is built , which take into account of the factors such as ship maneuverability , visibility and so on . in addition , based on the expert system theory , a design method of ship intelligent collision avoidance expert system is put forward , and the frame of ship intelligent collision avoidance expert system is built 在系統(tǒng)的研究過程中,首先對船舶避碰領(lǐng)域知識進行分析,并研究了船舶碰撞的原理、過程及對策;然后運用模糊數(shù)學(xué)理論,建立了一種評判碰撞危險度的模糊數(shù)學(xué)模型,該模型考慮了船舶的操縱性能、能見度等多種因素;接著根據(jù)專家系統(tǒng)理論,提出了一種船舶智能避碰專家系統(tǒng)的設(shè)計思路,并構(gòu)建了一種船舶智能避碰專家系統(tǒng)的框架;最后以visualbasic6 . 0作為軟件開發(fā)平臺,設(shè)計了一種具有良好的可視化人機交互界面的船舶智能避碰專家系統(tǒng)軟件。
( 5 ) establishing the measuring metallographic expert database with multi - modes express , obverse - contrary deduce method , fuzzy mathematical model pattern matching based on regulations . its reliability , accuracy and reappearance can satisfy requirement of quantitative analysis of metallographic microstructure . the system has great theoretical and practical significance in setting up quantitative relation among the composition , microstructure and mechanical property , selecting appropriate material , customizing suitable process and developing quantitative metallographic 廣東工業(yè)大學(xué)工學(xué)碩士學(xué)位論文利用本系統(tǒng)對金相組織自動分析的可靠性、準(zhǔn)確性能滿足一般定量金相分析的要求;它對于建立金屬材料成分、組織與性能之間的定量關(guān)系、合理地選擇金屬材料、制定合適的加工工藝、發(fā)展定量金相都具有重要的理論意義和使用價值。
