摘要
作为产品开发过程中的一项重要活动,工程变更会不同程度地延长产品开发时间,增加开发成本,对工程变更进行有效管理的能力反映了企业的敏捷性。由于变更传播的复杂性,工程变更管理研究中缺乏工程变更影响分析的有效方法。基于设计结构矩阵,建立工程变更影响分析模型,提出对工程变更的直接与间接影响进行分析的具体方法;综合变更的可能性影响和风险,并结合相关的变更影响计算方法实现了分析工程变更影响程度的预测手段。通过一个摩托车发动机变更设计的实例验证了所提出的计算模型的可行性。
Product development involves massive engineering changes. Engineering changes will prolong the time of product development and increase product cost more or less. The ability to manage engineering changes efficiently reflects the agility of an enterprise. Up to date there is a lack of effective methods to analyze and evaluate the impacts of the engineering change owing to the complexity of change propagation. Based on design structure matrix, an analytical model is set up, and the concrete method for analyzing direct and indirect engineering change impacts is proposed. Considering the probability and risk of engineering change, a mathematical model is presented to predict the comprehensive impact of engineering change. A motorcycle engine case study validates the feasibility of the proposed model.
