Before base logistics management and process were reengineered, sample statistics were obtained to identify and analyze the critical success factors (CSFs), which were then employed as evaluation criteria. The analytic hierarchy process was employed and 13 professionals and specialized managers at various levels (with an average experience of 22 years) were invited to nominate and rank 14 CSFs according to priority. The questionnaire results showed that 5 CSFs, specifically the people responsible (14.1%), issue priority (10.5%), organizational culture (10.1%), standard protocol (10.0%), and executors (9.8%), had the highest weights. To verify the feasibility of the proposed method, a field experiment was conducted with 1,036 samples obtained from second priorities and regular demands before and after process reengineering. A paired sample t test was conducted using SPSS 20.0. All results were significant, which indicates a substantial difference before and after the process reengineering. Subsequently, the results showed that the internal supply time for the second priority base decreased from 6 days 10 hours 4 minutes to 3 days 5 hours 11 minutes, reflecting a reduction of 49.8%. The off-base supply time decreased from 26 days 2 hours 12 minutes to 7 days 9 hours 38 minutes, reflecting a reduction of 70.4%. In contrast, the internal supply time for the regular-demand base decreased from 6 days 12 hours 42 minutes to 4 days 5 hours 11 minutes, representing a reduction of 36.9%. Lastly, the off-base supply time decreased from 16 days 2 hours 43 minutes to 7 days 40 minutes, which is a reduction of 56.5%. These results verify that the proposed method effectively enhances the effects of process reengineering.
