Embodiment Construction

[0065] The technical solutions of the present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0066] combine Figure 1 to Figure 3 As shown, the process of aquaculture input-output prediction method based on grey system theory is given, and the specific steps are as follows:

[0067]Step 1: Establish an economic input-output model during the reporting period, and obtain input and output coefficients. The data used are the actual data during the reporting period, reflecting the comprehensive balance of input and output during the reporting period.

[0068] Specifically, under the following constraints:

[0069] ( E - A ) X ≥ ⊗ ( Y )

[0070] ⊗ ( A ) A ≤ ⊗ ...

Abstract

The invention relates to an aquaculture input-output prediction method based on the grey system theory. The method comprises the steps that firstly, an economic input-output model in the report period is built, input-output coefficients are obtained, and a GM (1,1) model is utilized for predicating the final demanded aquaculture quantity ( the upper limit and the lower limit) and the resource guarantee degree (the maximum amount and the minimum amount); through qualitative analysis and quantitative study, the input-output coefficients in the future stages are corrected, and the gray input-output optimization model can be designed; finally, model calculating is performed to obtain a plurality of optional optimization schemes, the comprehensive argument evaluation is performed, and the most satisfactory scheme is determined. According to the method, method complementation is achieved, solving is easy, and grey target decision is facilitated.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a method for predicting input and output of aquaculture based on grey system theory. Background technique [0002] Aquaculture is an important part of my country's fishery, and it is also the main growth point of fishery development. The focus of my country's fishery development has shifted from "fishing-based" to "farming-based", which has led to great changes in the aquaculture industry. Various high-yield aquaculture methods such as factory fish farming, cage fish farming, and flowing water fish farming, ecological fishery with three-dimensional utilization of waters, combined production of water and land, and efficient utilization of energy have been widely used to maintain fishery resources. The production technology that reuses water resources and water resources to achieve sustainable development has also been increasingly accepted and mastered by producers. At the s...
