明智的技术决策需要对成本随时间的演变有一个结构化的理解。提出了一种集成学习曲线和基于过程的成本建模的动态方法来研究制造业中的学习。该方法适用于液压成形工艺的情况下，量化的周期时间，停机时间和废品率的学习改进的成本影响。与汽车装配和拉丝的情况下的比较表明，在学习的变化是绑定到个人的过程成本结构。结果表明，总成本的演变是强烈依赖于成本结构，主要的成本要素可能不符合主要的成本改进，通过学习的机会。这些分析可用于将有意识的学习活动集中在主要的学习操作驱动因素上。
Informed technology decision-making requires a structured understanding of cost evolution over time. A dynamic approach integrating learning curves and process-based cost modeling is introduced to examine learning in manufacturing. The approach is applied to the case of a hydroforming process, and quantifies the cost impacts of learning improvements in cycle time, downtime, and reject rates. A comparison with cases of automotive assembly and wire drawing illustrates that variation in learning is tied to the individual process cost structure. The results show aggregate cost evolution is strongly dependent on cost structure and that major cost elements may not align with major cost improvement-through-learning opportunities. The analyses can be used to focus intentional learning activities on primary learning operational drivers.
