A New Testability Allocation Method Based on Improved AHP

Testability allocation is one important job of testability design, for allocating relevant indexes to the lower levels of system. The traditional AHP is influenced by subjective factors, which make the final evaluation results unreasonable, and too far out of the actual condition. So the traditional AHP is optimized to make the results of testability allocation more reasonable and close to life, scale was improved, judgment matrix was modified, and expert eliminating strategy was introduced, and error caused by subjective reason was decreased and avoided, consequently testability optimization allocation method based on improved AHP was proposed. Example results show that this method is reasonable and corresponded to engineering practice.
