在分析并行工程下面向制造的产品设计（ＤＦＭ）的基础上，着重阐述了产品可制造性的评价方法，认为并行工程下的可制造性评价是一个典型的多层次、多属性的决策问题。建立了评价体系和基于模糊理论的数学模型，并给出了解法。
Based on the analysis of DFM, the evaluation method of product manufacturability is given. The evaluation of manufacturability under parallel engineering is a typical multi-level and multi-attribute decision making problem. The evaluation system and mathematical model based on fuzzy theory are established and the solution is given.
