A new concept of so - called " constraint degree " is introduced for a multi - objective programming problems , on the basis of which the compatibility of the programming problems is described by all sequences of the constraint degree 摘要对于多目标规划问题,提出了约束度的概念,基于此概念利用各个约束度序列可以刻划该规划系统的相容性。
In chapter 2 , by defining some concepts , such as constraint unit , constraint aggregate , constraint relation , constraint method , constraint chain , constraint degree and associate constraint sub _ aggregate etc . the basic constraint factors that affect the complex pipeline system packing are fully analyzed in the first . in the following , a mathematical modelling method used for complex pipeline system " optimization packing design is brought forth based on the optimization target decomposing , then a mode of generalized proposal field of the complex pipeline system packing design is constructed . finally , a variant genetic algorithm for the solution of the mode mentioned above is derived 第二章,通过定义约束元、约束集、约束关系、约束方法、约束链、约束度、关联约束子集等概念,对影响复杂管线系统规划布置的基本约束因素进行了较为全面、系统的分析;探讨了基于目标分解的复杂管线系统优化布置问题的数学描述方法,建立了面向复杂管线系统布置的广义布置方案场模型,并在此基础上设计了求解该模型的变异遗传算法。
The notion of explicitly geometric shape feature position of primitive is introduced , and the classification of explicitly geometric shape feature position is studied carefully . secondly , taken the combining principle of combined entity as the basis , the notion of explicitly geometric shape feature position constraint of combined entity is introduced . the classification - the explicitly reductive capacity to location dimension , constraint degree , dividing constraint level of explicitly geometric shape feature position constraint are systematically studied 其次,对组合体的组合机理进行了分析,并在此基础上,引入了组合体的隐式几何形状特征位的概念,系统的讨论了组合体的隐式几何形状特征位约束的分类、组合体的隐式几何形状特征位约束对定位尺寸隐含性缩减的性质、组合体的隐式几何形状特征位约束的约束度、隐式几何形状特征位约束的优先级别划分。
