THE METHOD OF JUSTIFYING THE CHOICE OF THE PARAMETERS OF MINING VESSELS
The article describes the method of justifying the choice of the parameters of mining vessels. It is proposed a system of independent variables, including technical features of the fishing vessels; technical and production characteristics of the technological equipment of the vessel; technical and production characteristics of fish cleaning area; operational and production characteristics of vessels; economic indicators. The layout of the design economy of the vessel is given. The system of indicators of independent variables is developed. As a criterion for the selection of indicators of independent variables is proposed the maximization of the vessels’ profitability. Methods for calculating income, costs, and construction value of the vessel are provided. The system of simulation models based on computer modeling and the expediency of their use are proposed. Determining the construction cost of the vessel is proposed on the basis of the cost of a prototype. If projected vessel does not coincide with it, it’s offered to adjust its value based on the new project. Given market that prices can change, it’s invited to vary them within reasonable limits. This also applies for determining the value of the vessel and in the calculation of income and expenses. At the first stage the calculation of profitability is made on a vessel-prototype. In a subsequent variation of the price calculations are repeated for the second and each subsequent iteration and compares the obtained values of the objective function and determined by its maximum value during iterations. The calculation is terminated after determining the stability of the decide.
