基于CAIV 的机械产品设计方案费效权衡优化

针对民用机械产品设计方案选择时,既要考虑客户对产品的功能需求,又要符合企业费用目标约束的问题,采用基于以费用为独立变量(CAIV)的费效权衡优化方法,以混凝土泵车系列产品为研究对象,运用主成分回归和层次分析(AHP)方法分别构建生命周期费用和效能模型,并以费效比为优化目标权衡得到最优方案.研究表明,采用CAIV费效权衡方法选择的设计方案,可以实现产品全生命周期成本目标的有效控制.

Mechanical product design cost-effective trade-off based on CAIV

Aiming at the decision optimization problem of the civil mechanical product design scheme which needs to consider the customer demand of products function, but also consider cost constraints, the study is made on the concrete pump truck series performance-cost trade-offs and decision-making using cost as an independent variable(CAIV) method. The life-cycle costs and performance models are built by using principal component regression and analytical hierarchy process(AHP) methods respectively. Then the optimal solution is obtained with cost-effective ratio. The results show that the product life cycle cost targets can be controlled effectively by using the design program traded-off with CIAV.
