A novel hybrid algorithm, which combines predictor-corrector primal-dual interior point method and genetic algorithm, is presented for dynamic and static reactive optimization in this dissertation. The algorithm fully make use of the advantage of interior point method in solving successive optimization problem and the advantage of genetic algorithm in solving discrete optimization problem. The original problem is divided into three parts: total successive problem, discrete problem and successive problem.

After a further analysis based on the empirical results,a trial probe on the cognitiveprocessing mechanism of the problem representation of the word problem in two types of MLDwas made by the author.The MRD performed much poorer than the MLD only in the mostdifficult equation listing of word problem and the medium and most difficult problemrepresentation of word problem,which showed no difference in computation and comprehensionof simple meaning of the problem,but the gap between two types of MLD became wide as afunction of difficulty and cognitive loading.It indicated that the MLD only had some advantage over MRD for they used more cognitive skills to solve the problem.

基于以上实验的结果，对两类数学困难小学生的应用题问题表征的认知机制作如下推断：混合型数学困难学生仅在高难度水平的应用题列式成绩和中高难度水平应用题问题表征水平上比单纯型数学困难学生得分显著低下，表明两类数学困难小学生在计算能力与理解简单题意的能力上并无差异，但随着难度提高，认知负荷加重，两类数学困难学生在应用题解题上的差异得以突显，表明当需要运用更多的认知能力解决问题时，单纯型数学困难学生比混合型困难学生更具优势。

This will promote to the airline company improving services and enhance level of management and benefit of operation. This will advances the development of national economic and meet the requirement of people life and business activity, and increase the living quantity, and adapt to the travel industry to make use of. Everyone in the civil aviation should pay attention to.This paper analyzes the problem of development of regional aviation transport from three angles. Combining with the background of our country social economy development, and the speeding and improving service and advancing the marketing means, the compete power of three main transportation modes of regional aviation and railroad and highway in our country. From angle of tripper, a mathematical model of trip cost is established to quantitatively describe the choice behavior of passengers to select the model transportation. A

结合我国社会经济发展的背景，以及地面铁路和公路不但提速、改进服务和营销手段的现状，首先定性的分析了我国目前主要的三种客运方式支线航空运输、公路运输和铁路运输的竞争能力，然后从旅行者的角度，使用旅客出行成本模型，对成渝线、福厦线和台高线航线上不同出行方式的出行成本进行了对比研究，提出降低旅行成本，增强支线航空运输竞争能力的建议和方法；接着提出了利用层次分析法和模糊评判理论，对目前国内所采用的支线机型进行分析比较的方法，建立了选择支线机型的方法和评判标准，这给航空公司在发展支线航空选择机型时提供了一种评价选择方式；然后应用博弈论的方法、模型，分析支线航空运输航线结构变动时各种运输方式的经济行为、成因、结果及合理措施，提出航空公司发展支线航空运输的对策；最后对我国支线航空运输的现状进行了分析，并对未来支线航空运输的发展进行了预测，有针对性地提出了我国支线航空运输的发展策略。
