给出了快速成型制造中关于零件制作方向的3种单目标优化模型,单目标优化分别以提高原型表面质量、减少支撑和减少制作时间为目标;单目标优化模型的解集包含了此目标意义下零件的最优和较优分层方向。在此基础上,提出了零件制作方向优化的带权-p模理想点综合决策模型。文章设计了一种经改进的混合遗传算法,并用其对零件制作方向优化的3种单目标模型及综合决策模型进行了求解。
Three kinds of single-objective optimization models for parts manufacturing direction in rapid prototyping manufacturing are given. Single-objective optimization aims at improving the surface quality of the prototype, reducing support and reducing the production time respectively. The solution set of the single-objective optimization model includes the target meaning Under the best parts and optimal stratification direction. On this basis, a comprehensive decision-making model of weighted-p-mode ideal point is proposed. In this paper, an improved hybrid genetic algorithm is designed and used to solve three kinds of single-objective models and integrated decision-making models that optimize the production direction of parts.
