constraint relation meaning in English
约束关系
Examples
- 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。 - main contents list as follows : 1 . eai communication mechanism of vrml 2 . feature based model restructure 3 . mapping algorithm of model 4 . assembly processing analysis 5 . creating mechanism of assembly model 6 . optimization of model 7 . assembly constraint relations processing prototype system of web-based interactive virtual assembly platform is developed based on studies above, and its functions, such as data management of network virtual product, definition of assembly tree structure, control of assembly, etc, are implemented and have gotten well engineering application effect
