基于设计结构矩阵的产品多域需求表达合理性研究

摘要/Abstract

摘要： 需求节点之间存在约束关系及时序关联，造成需求节点矛盾冲突，为此，提出一种基于设计结构矩阵(DSM)的客户需求表达方法。该方法通过建立客户需求模板、建立约束规则、优化客户需求表达过程DSM、进行约束检验、计算需求合理度5个步骤，实现产品需求的多域协同，为需求节点时序合理性及需求表达合理性提供量化判定依据。最后以AGV小车为例说明方法的实用性。

关键词: 客户需求, 约束规则, 设计结构矩阵, 需求表达合理性

Abstract: Facing to the conflict problems of customer requirement nodes due to constraints and node sequences, an expression method of customer requirements was proposed based on DSM. This method was composed of five steps: building customer requirement templates, building constraint rules, optimizing the DSM of customer requirements expression processes, checking the constraint rules, calculating the rationality of customer requirements. The multi domain collaboration of product requirements was realized and quantitative basis for judging the rationality of requirement node sequences and requirement expressions was provided. Finally, the practicality of the method was illustrated by automatic guided vehicle(AGV).

Key words: customer requirement, constraint rule, design structure matrix（DSM）, rationality of requirement expression
