低水平目標-
Details are as follows : we deal with properties of bilevel linear programming and prove the equivalence of bilevel linear programming and optimization over the efficient set. a class of multi - objective tow level programming, i. e. the upper - level is single objective and the lower - level is linear multi - objective, is mainly discussed. it can be converted into the optimization over the efficient set with parameter and an algorithm is given with its finite termination being proved ; when the upper - level is linear function, an exact penalty function algorithm is given
分層（分級）遞階系統是社會組織管理的主要形式，多層規劃是研究這類系統優化問題的基本模型，其鮮明的實際背景和廣泛的應用前景引起了人們的廣泛關注，成為一個新興的活躍的研究領域，本論文研究了二層規劃中的若干問題，主要工作如下：討論了二層線性規劃的性質，並證明了它與零有效集上優化問題的等價性；對一類二層多目標規劃（上層為單目標規劃、下層為線性多目標規劃的問題）進行了探討，將其轉化為含參變量的有效集上的優化問題，進而給出了一種演算法，並證明了該演算法的有限終止性；當上層為線性單目標時，給出了一種罰函數方法 -
In chapter 3, the group decision - making is applied in the safety evaluation, and the credit degree is put forward to considering the experts " appraisal level. the principle of set - valued statistics and the fuzzy gravity center based decision theory are put into a new method, and are applied in the uncertain type of ahp. hence, the weights of evaluation indices that reflect the experts " level are gained. this measure, which reflects the objective of the evaluation process and the subjective of the experts, can concentrate various opinions and lower the deviation of the evaluation process. a new method of calculating weights and variable weight is presented in the safety evaluation, and it is discussed that how the method of variable weight is applied in several evaluation methods
在原有的集值統計原理的基礎上，引入對專家評判水平的評判? ?專家的權重，形成加權的集值統計原理，並與重心決策理論相結合，計算出考慮了專家水平差異的橋梁安全性評價指標的權重。這樣處理反映了評價的客觀性和參評人員的主觀性，能很方便地集中多種不同意見，減少了評價過程中的隨機誤差。在橋梁安全性評價中，為了反映橋梁狀態發展的不均衡性，使評價過程更趨于合理，評價結果更可靠，將變權原理應用於橋梁安全性評價，探討變權原理在多種評價方法中的運用。 -
Though the expression level of bl21 ( de3 ) / pt221 - hyuh was lower than that of m15 / pqe60 - hyuh, the target protein of bl21 ( de3 ) / pt221 - hyuh was principally in soluble form while the objective protein of m15 / pqe60 - hyuh was principally in insoluble form. both of the products in the two strains showed biological activity, but the former is 2 times higher than the latter. the hyuc dna fragment was inserted into ppic3. 5k plasmid to construct the ppic3. 5k - hyuc recombinant plasmid which was then transduced into pichia pastoris gs115 cells after being linearized by bgl ii digestion
結果表明， sds - page分析在50kd處有一較強的表達帶，融合有分子伴侶的重組菌株bl21 （ de3 ） pt221 - hyuh與非融合表達的重組菌株m15 pqe60 - hyuh相比，乙內酰脲水解酶的表達量低一些，但其表達蛋白主要以可溶性形式存在，而m15 pqe60 - hyuh中表達蛋白則主要以包含體形式存在，且前者的酶活性是後者的2倍多。 -
After introducing fuzzy goals for objective functions, a fuzzy interactive decision making methed is presented to derive a satisfactory solution for decision makers by consulting the ratios of satisfaction between the leader at the upper level and the follower at the lower level
在引人目標函數的模糊目標，並充分考慮上層與下層決策者的滿意度后，構造了一個模糊互動式決策方法，從而使得上下層決策者對最後的求解結果都能滿意。
