Research of Engineering Change Analysis

An engineering change is costly and time consuming. Therefore, the research of effective methods and software is highly significant to engineering change analysis. This paper has conducted research on the engineering change analysis method and decision support environment. The characteristics of an engineering change were demonstrated; the data model was set up for supporting engineering change analysis; the method for analyzing engineering change propagation was proposed. The multi-user dynamic analysis of an engineering change and storage of the engineering change scheme with reusability were achieved in this paper. According to the results, the research shows more flexible and efficient to analyze engineering changes and further assure the completeness of changed data.
