当前较大规模的功能树组合求解方法存在解空间庞大、冲突定位困难的问题,对此提出了一种基于功能集族的功能求解方法。在布尔代数理论基础上,把功能树结构映射为功能函数,通过求解功能函数的功能集族来对功能树进行求解。给出了从功能树生成功能集族的实现算法。实践证明,该方法可有效地提高设计者进行概念设计的效率。
Combination is widely used in conceptual design, but two problems are met: the solving space is too big for designers to solve and the conflict is difficult to orient. A new function solving method based on function family is given by mapping the functional tree with the performance function. The new method is proved to enhance the designers' work efficiency with the instance.
