- W4382564787 abstract "Linear programming is an important branch of operational research, which has been studied earlier, developed faster, applied widely, and used more mature methods. It is a mathematical theory and method to study the extreme value problem of linear objective function under linear constraint, which is widely used in economic analysis, management, engineering technology, industrial and agricultural production, etc., it provides a scientific basis for making optimal decision with limited human, material, and financial resources. Generally, under the condition of linear constraint, the problem of finding the maximum or minimum of linear objective function, the decision variable, constraint condition and objective function are the three elements of linear programming. However, there are many uncertainties in fisheries production and aquaculture, such as the impact of the global climate and marine environment on the early life histories of fish, the impact of fishing practices on target species and their ecosystems, and so on, these cannot be expressed by an exact value, so there are many uncertain and fuzzy factors in the social economic system and natural ecological environment system of fishery production, the phenomenon is always gray, and the wrong results may appear when the traditional linear programming is used to analyze and deal with the problem. The emergence of Gray system provides a way to solve this problem. Gray linear programming is a kind of dynamic linear programming, which can be used to solve the problems of conventional linear programming and achieved good results. In this chapter, the gray linear programming model and its calculation method are introduced, and the application of gray linear programming in fishery science is analyzed by taking the study on the adjustment of marine fishery structure in Shandong province as an example, the development trend of fisheries in Shandong province is forecasted scientifically, the power and composition of fishing vessels of different grades are calculated, and the suggestions for the adjustment of marine fisheries structure in Shandong province are put forward." @default.
