食用豆腐生产经营过程中区间决策问题的研究

The Resach about Interval Decision Making Problem for Making and Management of Tofu

研究了豆腐作坊生产经营豆腐的最优决策问题.深入的实际调研表明:随着自然环境的改变、生产条件和市场资源的变化,豆腐作坊的净收益表现出不确定性.于是豆腐作坊的最优净收益就呈现出区间的特性.以豆腐作坊最优净收益为目标,首先建立了两大区间决策模型-改变生产规模的区间决策模型和不改变生产规模的区间决策模型.其次给出了有关区间决策的基本定理及求解方法.最后对实际问题进行了求解,从而为豆腐作坊提供了最优净收益的范围—区间,并对求得的结果进行了分析,说明所给的求解方法及所得结论是正确的.

In this paper, we consider optimal decision making problem about making and management of tofu in the tofu factory. The real research in the tofu factory is： with the changing of the nature envoronment, the producting condition and market source, the wet profit of tofu in the tofu factory is not distinct. That is the wet profit of tofu in the tofu factory takes on interval character. First, we take the wet profit of tofu as the function, establish two interval decision making models-interval decision making model of changed producting scale and unchanged one. Second, we give some theorems and a method for Solving the interval decision making problem. Then, we solve the above real problem and give optimal wet 15rofit interval for the tofu factory. Finally, the result is analyzed, it proves the method is right.
