Research on Ship Maintenance Level Determination Method Based on Improved TOPSIS Method
As the traditional maintenance level determination excessively depends on the objective judgment of the experts and lacks the research on the structural characteristics of ship equipment,a algorithm for determining maintenance levels in ships based on an improved Technique for Order of Preference by Similarity to Ideal Solution(TOPSIS)method is proposed.This algorithm conducts level classification for such factors such as operational activity,maintenance environment level,human resource levels,etc.and determination modes.The maintenance level determination indicators system is constructed,and a gray relational analysis-based improved TOPSIS evaluation method is introduced to calculate relative correlation degree as a basis for determining maintenance levels.The feasibility of the maintenance level determination algorithm in a virtual environment is further validated through the development and construction of a software module with CATIA.The results indicate that determination results by the algorithm are reliable,reasonable,and consistent with the actual situations,the guiding proposal is provided for ship equipment maintenance work,structure design,and maintenance.
