摘要：It is shown that there are many mathematical models (MM) of ship power plants for various purposes. Such MM are integrated into decision support systems (DSS) and used in the design and power optimization of ship power plants (SPP) of various constructional configurations. Experimental research and scientific literature analysis prove that such integrated MM into DSS are not always adequate to real physical processes in some modes, for example, dynamic ship positioning.That is why integrated MM SPP into DSS need clarification as well as the existing DSS need further development.The approach for the creation of specialized DSS SPP of the ship combined propulsive complexes (CPC) is proposed, which allows predicting the number and type of thrusters (T), pods, power system, and does not require the application of similarity criteria, allows a multiple analysis of the structure at minimal initial data.The designed DSS applies the principles of the construction of DMI-models ships and methods of implementation of characteristic spatial vectors of power processes, gives a possibility to synthesize recommendations to T designers, controllers and power systems for ships operating in the dynamic positioning modes. Created DSS can be used practically for any type of vessels and adapted for the modes of dynamic ship positioning.It is established for a given rotation speed of the pods, traction, torque and stepper ratio with the help of created DSS, that traction coefficient grows with the change in mutual location of T relative to each another and diametrical plane of the vessel. It is proved that the interelation of thrusts coefficients are correlated better with the power coefficients than with the stepping pods coefficients, allowing increasing energy efficiency of SPP CPC in the dynamic positioning modes.The results of the research can be implemented into data bases of similar DSS and provide researchers with verified information needed for creation of new concepts of SPP CPC design for modification of existing systems.
