The deposited silt will not only influence its routine assignments but also decrease its strategic advantages. There are several military harbors in the Navy, yet we could not dredge them effectively in the past due to less experience and capability. Therefore, it becomes an important issue for Navy to investigate the problems and to develop an evaluation model for effective dredging cycle. In this study, Fuzzy Delphi Method was firstly used to choose 15 important dredging factors from literatures, regulations, and results of the experts’ interviews and questionnaire. We separate these 15 factors into 4 criteria (Engineering economy, Risk management, Engineering technique, and Environmental impact) to establish a complete analytical structure, and then we use Fuzzy Analytic Hierarchy Process (FAHP) method to evaluate the weight of each criterion. At last, the best dredging cycle is calculated after summing the weights of all criteria by using Simple Weight Method. Besides the above results, another important findings show that the experts with different background have different suggestions about dredging factors. And these findings provide useful secondary information for future dredging plan. In the end of this research, a case study about the dredging cycle evaluation is investigated for a particular military harbor in southern Taiwan. We use the evaluated process proposed in this study to estimate the best dredging cycle successfully. It proves the developed model’s validity and applicability.
