A COMPUTER DESIGN MODEL FOR OPTIMIZING FISHING VESSEL DESIGNS BASED ON TECHNO-ECONOMIC ANALYSIS

A computer design model is developed for the preliminary design of fishing vessels for the given fishery in question using techno- economic calculations to achieve operational benefits. The model can analyze five types of commercially important fishing methods: bottom trawling, pelagic trawling, gillnetting, longlining and purse seining. Analysis of a vessel engaged in single fishery or multi- fisheries adopting more than one fishing technique during diferent seasons in its annual operation can be made. The model contains the relationship/submodels for determining the main dimension of capacities, propeller calculations, installed engine power, fish catching power, supplies required for a given trip, econmic freerunning speed, fuel consumption, investment calculations, operation budget, and seasonal account. The optimum vessel can be determined by varying decision variables and determining the capital recovery factor as the economic criteria. Fish hold volume, which is related to the vessel's main dimensions, is the main decision variable considered in the model. The economic analysis for the existing fishery and for the future fishery is suggested. The performance of the model under the selected constraints is detailed.
