1. Introduction Rolling bearings are intricately integrated into the framework of shipbuilding and manufacturing technologies, performing a vital role in a myriad of applications, from marine steam turbines and aft power compartments to connecting pipelines and propulsion shaft systems. Within the ship propulsion system, the bearings endure a variety of stressors including vibration [1], torsion [2], and coupled axial [3] and lateral [4] loads.

5.3. Comparison of Different Approaches Different approaches are compared in this section to verify the effectiveness of the QL-CNP algorithm. The proposed QL-CNP algorithm was used to solve the MADP in this study. Furthermore, the general contract net algorithm (CNA) and Dijkstra algorithm were also compared to conduct performance analysis of different approaches. Dijkstra is a classical shortest-path algorithm that is usually used to find optimal routes [44].
