摘要
建立了基于灰色系统理论的投入产出优化模型,并将其运用于水产养殖的投入产出分析。在获得投入、产出系数后,利用GM(1,1)模型预测最终水产养殖的需求量(上下限)、资源保证程度(最高量和最低量);然后通过定性分析与定量研究,对未来各阶段投入产出系数进行修正和设计灰色投入产出优化模型;最后进行模型计算,取得多种可供选择的优化方案并进行综合论证评价后确定最满意方案。该模型做到了方法互补、求解比较容易而且便于灰靶决策。
Based on grey system,this paper established an input-output optimization model,and the modelwas used to analyze the input-output of aquaculture.After gotten the coefficients of inputs and outputs ofaquaculture,using GM(1,1) model we could predict the final demand for aquaculture(upper and lower),theresource level of assurance(maximum-minimum volume);then through qualitative analysis and quantitativeresearch,the future input-output coefficients for each phase was revised and the grey input-output modelwould be designed.Finally,using model calculations,we could obtain various options.After the comprehensivedemonstration,we could get the most satisfactory solution.From the numerical results,the model couldcomplement each other,quick to solve and make grey target decision easily.
