本文立意在中國目前的經濟背景下，力圖通過對國內外城市建設用地政策及我國城市建設用地指標的回顧，剖析城市建設用地指標的影響因素，並根據我國的實際情況，分析技術發展對城市建設用地指標產生影響的必然性，最後，針對上海這一具體城市的技術發展和經濟狀況進行分析，對現階段上海市的城市建設用地指標提出相應的建議。 -
The confirmation theory which is one of the uncertain inferring model has been adopted to construct the inference engine, for the special knowledge in the field is uncertain and fuzzy. at the same time the knowledge on fuzzy set theory and fuzzy logic has been applied to calculate the final value about certainty factor value ( cfv ) of a rule through inputting several initial values
根據專門知識的不確定性和模糊性，運用非精確推理模型中的確定性理論，組織實現系統的推理機，在對規則可信度進行不確定性處理時，引入模糊集合論和模糊邏輯的有關知識，處理多個初始可信度的輸入，由此得出最終比較可靠的規則可信度。 -
The probabilistic approaches include the belief network, the dynamic causality diagram, the markov network, the approach used in prospector, etc. the non - probabilistic approaches include the certainty factor theory in mycin, fuzzy set logic, dempster - shafer theory, etc. the non - probabilistic approaches have reached some achievement in their respective application domain, and shown their shortage while applying
另一類是非概率的方法，包括mycin的可信度因子（ certaintyfactor ） 、模糊邏輯（ fuzzylogic ）以及dempster - shafer的證據理論等。非概率的方法雖然在各自的應用領域都取得了一定成果，但在運用過程中人們越來越意識到這類方法的不足。 -
Since traditional certainty methods have some instinct limitations, this paper comprehensively considers the uncertainty of the friction strength value between the nail and soil, the strength factor of soil, and so on. after dealing with the factors and their relation, the reliability of the soil - nail retaining structure is analyzed and its calculating formula is educed
鑒于傳統的確定性分析方法的局限性，本文綜合考慮了土釘與土體之間的界面摩阻力強度值及土體強度參數等的不確定性，經過對各參數及參數間關系的處理，對土釘支護結構的內部穩定性進行了可靠度分析，得出可靠度的計算公式。 -
This dissertation discusses and studies to surround the knowledge representation, learning, reasoning, and the main contents include : at the first chapter, some familiar uncertain knowledge representation and reasoning and the difficulties of them : evidential theory, certainty factor, fuzzy logic and fuzzy reasoning, subjective bayesian method, belief network are introduced. we present the basic knowledge, primary reasoning algorithm, complexity of reasoning algorithm, the way of dealing with some problem of causality diagram relative and the research direction in causality diagram theory particular at the second chapter
論文圍繞著因果圖的知識表達、學習、推理進行了討論和研究，主要內容包括:在扼要介紹了一些比較常見的不確定性知識的表示和推理方法:證據理論、確定性因子、模糊邏輯與模糊推理、主觀bayes方法、信度網的基本知識之後，比較詳細地闡述了因果圖的知識表達，主要的推理演算法、計算復雜度以及對一些問題的處理方式方法。 -
Secondly, the mode based on the expert system of the uncertainty reasoning in teaching methods is discussed emphasizely, and the theory of certainty factor is applied to the mode, then we develop an expert system program by using clips language. in the system, fuzzy knowledge expression and reasoning based on the production rule are realized, so that we can perferably realize the intelligent and individual property of icai
然後探討了採用基於不確定性推理的專家系統實現對教學方法的選擇的方式，將可信度理論嘗試性地運用於教學方法的選擇上，並使用clips （ clanguageintegratedproductionsystem ）語言開發了一個實際可行的教學方法選擇專家系統，實現了基於規則的模糊知識表達與推理，從而較好地實現了icai系統中的個別化和智能化教學。 -
Finally, according to the process of selecting uncertain parachute design parameters, we present the fuzzy knowledge representation combining production rule with certainty factor and possibility - distribution function. on these bases we establish a fuzzy decision model, using rule - based reasoning and synthesized fuzzy evaluation, for uncertain parameters
