2005: Decision Support System for Fisheries Management
نویسندگان
چکیده
This paper presents a decision support system that is oriented toward fisheries policy and management decisions. The important current issues involve the development of an optimal harvesting plan for the fishing industry. A simulation optimization has been built to assist authorities in scheduling for a fleet of hundreds of vessels in terms of time and location of fishing, as well as amount and target species to be fished. Marine fisheries are highly complex and stochastic. A simulation model, therefore, is required. Simulation-based optimization utilizes the simulation model in obtaining the objective function values of a particular fishing schedule. A Genetic Algorithm is used as the optimization routine to determine the optimal fishing schedule, subject to fleet capacity and conservation requirements. The decision support system is then applied to the real situation in the Northeastern U.S.

A framework for risk analysis in fisheries decision-making
Failures in fisheries management have been linked to our inability to embrace the inherent uncertainty of fisheries systems. Fisheries decisions should be made on the basis of integrated evaluations of strategy alternatives, where comparisons of comprehensive scenarios incorporate strategic biological and socio-economic objectives and constraints, and explicitly take account of system uncertain...
متن کاملSIMPLE DECISION GUIDELINES FOR TERMINAL FISHERIES TARGETING ATNARKO RIVER, BRITISH COLUMBIA, CHINOOK SALMON (Oncorhynchus tshawytscha)
Simple decision guidelines (SDG) describe the basic components of more complex decision-support tools. These components are: (1) management objectives, (2) management options, and (3) guidelines for assessing stock status and responding accordingly. In close cooperation with the local fisheries manager, I developed SDG for terminal fisheries targeting Atnarko River chinook salmon. To describe m...

A Model-Driven Decision Support System for Software Cost Estimation (Case Study: Projects in NASA60 Dataset)
Estimating the costs of software development is one of the most important activities in software project management. Inaccuracies in such estimates may cause irreparable loss. A low estimate of the cost of projects will result in failure on delivery on time and indicates the inefficiency of the software development team. On the other hand, high estimates of resources and costs for a project wil...
