Optimization of ship form and fishing net of trawlers
摘要
Abstract
In the optimization and analysis of trawlers ship forms, the factors such as the ship itself, fishing ground, fishing anchorage and fishery market and fishery resources should be considered to select fishery net matching to ship fishing capacity so as to seek the optimal ship forms. In this pager, the relation of ship forms and fishing net yield of trawlers was studied, based on which, an optimization model of trawlers ship forms was designed by using index weight method with ship length, molded breadth, molded depth, block coefficient and design speed as optimized design parameters, and the net present value, fishing effect coefficient, investment payback period, tons of fish oil, tons of fish cost were selected as economic evaluation indexes of ship forms. And the technical and economic evaluations of ship forms were conducted. Taking the change-layers big trawlers operating in South America waters as a calculation case to optimize and analyze the model, the optimal ship form solution and fishing net yield were obtained, which can be referred as parameters and fishing net for the the ship form selection. The optimization method can be applied in the trawlers evaluation stage, so as to achieve the aims of optimize and analyze the ship form and fishing nets of the trawlers.关键词
