WSEIAC Model and Its Extension for System Effectiveness Analysis
用于系统效能分析的WSEIAC模型及其扩展

In the paper, WSEIAC model suited to the system finishes multi\|mission in single stage is inferred mathematically, and is extended to case in which the system finishes multi\|mission in multi\|stage. Of which, it is introduced how to express system effectiveness as single numerical quote in WSEIAC model, and their use condition also.
