Process oriented maintainability and maintenance task integrated analysis method

A process oriented integrated analysis methodology (POIAM) is presented in the paper, aiming at the imbalance between maintainability analysis (MA) and maintenance task analysis (MTA) in practical project. The paper presents the correlativity between maintainability factors and maintenance task, support resource requirement and the maintenance task, products and support resources to achieve the process oriented integrated analysis. Based on the analysis flow of MTA, an integrated analysis process is invented, which can expose design defects effectively. Besides, the methodology put forwards the composed measures for design improvement through screening key problems from analysis results.
