摘要
设计过程就是满足约束的过程。在并行设计中，需要考虑来自产品全生命周期中的各种约束。根据这种思想，提出了基于约束的产品评价方法。文中研究了约束满意度和权重的表达，从而对并行设计的评价可根据设计过程中涉及到的约束的满意程度的合成来实现。在此基础上，提出了一种基于约束的产品综合评价方法。最后，给出了基于约束的评价系统的结构和工作原理。
Concurrent design has to satisfy all constraints in the life circle of the product. Evaluationg of the quality of concurrent design can be performed by the synthesis of the degree of constraint satisfaction. So a kind of constraint based evaluation method of product is presented. Firstly the paper expands the concept of constraint by adding satisfaction degree function and fuzzy weight of constraint to it. Then a synthetic evaluatin method is introduced. finally a constraint based evaluation system is given.
