MATHEMATICAL STATEMENT OF THE PROBLEM OF MARINE POWER PLANT OPTIMIZATION
The paper deals with the problems of complex optimization of thermal power plants in general and ship power plants (MPP) in particular, characteristics of parameters, limitations, optimization methods. Generalized mathematical formulation of the problems of optimizing the characteristics of MPP is to determine the maximum or minimum of a nonlinear function. The mathematical model of the MPP of the installation is a set of basic and auxiliary essentially nonlinear equations. When finding the maximum or minimum of the goal function of many variables, a complex system of equations is often obtained, the explicit differentiation of which is difficult or impossible. In most cases, you need to solve problems that have restrictions not only in the form of equalities, but also inequalities. Provides guidance on the definition of the objective function. The results of research on the possibility of using recycling absorption refrigerating machines on small vessels of the fishing fleet are considered.
