| 1. | The applications of mathematic programming , as one important ramification of operational research , have been infiltrated through many fields 数学规划是运筹学的一个重要分支,并已被广泛应用到各种领域。 |
| 2. | All kinds of classical theories of mathematic programming are enumerated with their development in the near future ^ and typical solution , and the oil well orbit optimized theories are introduced also 本文较为全面地阐述了数学规划所涵概的各种经典规划理论以及近期研究状况和代表解法;并简要介绍油井轨道最优控制理论的工程背景和研究意义。 |
| 3. | Because there is lots of uncertain information in optimization based image reconstruction from projections , fuzzy vector mathematic programming algorithm for image reconstruction from projections is therefore proposed 由于优化图像重建过程中存在着许多不确定的随机模糊信息,因此,作者采浙江大学博士学位论文用模糊向t优化法来求解图像重建问题。 |
| 4. | The usual methods of dealing with stochastic or fuzzy chance constrained linear programming are converting the chance constraint conditions to respective definitive or clear mathematic programming problems to compute them , according to given belief level 求解随机或模糊机会约束线性规划的传统方法是根据事先给定的置信水平,把相应的机会约束转换为各自确定的或清晰的数学规划问题进行计算。 |
| 5. | In the case of complex situation , the obtained definitive or clear mathematic programming problems are usually nonlinear programming which bring complexity to computing , and even some stochastic or fuzzy problems are difficult to convert to definitive or clear problems 这是因为,对较复杂的情形,得到的确定或清晰的数学规划通常是非线性规划,给计算带来复杂性,甚至有些问题难以转化为确定或清晰的数学规划问题。 |
| 6. | In view of the fact that there is inevitably noise in actual projections , single objective ca n ' t express reconstruction characteristic accurately , so the author pays more attention to other objectives of reconstruction image to make full use of the mutual information among the incomplete projections and the vector mathematic programming is presented to solve the imaging problem 鉴于实际投影中存在不可避免的噪声,单一目标无法准确描述重建特性,为此需兼顾重建图像的其它指标,更好地挖掘不完全投影数据之间的相互信息。于此,作者提出采用向量优化法来表述成像问题。 |
| 7. | In the chapter 3 , algor feas ( also called super sap ) , a commercial fem software is introduced ; several . problems in building the finite element model of a auto frame is researched ; taking advantages of fem and mathematic programming , a strength analysis method of the frame of a series multi - spindle hydropneumatic suspension automobile is proposed ; taking the structure and load characteristic of a missile ' s frame into account , the static , eigenvalue and response analysis have been made by using super sap91 第三章简要介绍了大型有限元软件sap91 ;对车架有限元建模及分析中的若干问题进行了讨论;利用有限元法和数学规划法相结合,提出了一种串联多轴油气弹簧悬架车辆车架强度分析的方法;针对某导弹发射车车架的结构和载荷特点,利用sap91软件对其进行静力分析、特征值分析和动力响应分析。 |
