In this study, we propose a new method for extracting maintenance preconditions. Graph structures are used to represent relationship among SSCs. Maintenance preconditions are extracted by analyzing the graph structures. Furthermore, we propose an automatic maintenance scheduling method using extracted maintenance preconditions. Design issues could be extracted based on the created maintenance schedule. A simple example is presented to illustrate the proposed method.
