变型设计中产品尺寸的成本影响及控制规则研究

Research on Cost Effect and Control Rule of Volume Size in Variant Design

本文从分析与产品体积与尺寸有关的材料成本、加工成本、准备成本三个成本项目入手,通过定性或定量分析尺寸影响成本的原因,建立了一个量化的模型,可从原型产品的原有成本结构推导出改型产品的新的成本结构,以利于寻找成本降低的重点及控制规则,最后通过大量的统计数据总结出成本降低规则,有助于变型设计中成本控制实施。

By analyzing the size-related material costs, processing costs, preparation costs, and through qualitative or quantitative analysis of size-effeeted cost, the article establishes a quantitative model to derive the new cost structure from the cost structure of the original prototype, which facilitate the search for cost reduction focus and control. At last the cost reduction rules are summarized through the statistical data to contribute to variant design in the cost control.
