| Abstract: | When a water aerodrome and a navigation channel coexist on a same water surface, seaplanes and ships may encounter each other, which may influence the takeoff, landing, and taxiing of seaplanes, and the navigation safety of vessels in nearby waters. To ensure the safety of seaplanes and vessels, it is extremely important to evaluate the rationality and the safety of water aerodrome site. A method for site evaluation of water aerodrome based on a combined weighting method and a cloud model is proposed. An evaluation system is developed in order to appropriately evaluate the appropriateness of the site of water aerodrome, which include four first-level and 11 second-level indicators from the following aspects: meteorological, hydrological, navigable, and airspace environment. An improved analytic hierarchy process and an entropy weight method are used to obtain the subjective and objective weights of the evaluation indicators, respectively. Then, a gaming model is used to determine the optimal linear combination coefficients of these subjective and objective weights by minimizing the deviation, in order to find the combined weights. A synthetic evaluation model based on combined weighting and a cloud model is developed. Taking Dalu water aerodrome in the City of Zhenjiang as a case study, study results show that the evaluation result of the site of water aerodrome is good. There hasn't been no accident since the water aerodrome is under operation. The evaluation result is consistent with observed safety condition of the airport. The cloud model used can well address the uncertainty in the selection of the membership function by balancing the randomness and fuzziness of data in the evaluation process of any evaluation method using fuzzy mathematics, which further increases the reliability of the evaluation results from the proposed method. Study results show that the evaluation outcomes from the proposed method are similar to those from the classical fuzzy comprehensive evaluation method, which verifies the validity as well as the practicability of the model. The proposed model can be applied for the site selection of the water aerodromes to be built, and also for the evaluation of the safety of existing water aerodromes. |
