《华东林业调查规划情报》1984年第三期周世勤同志曾用线性规划理论对森林收获量调整作过初步的分析研究。但正如文中所说“在变量Xi增加的情况下,用手工迭代计算不能达到目的,必须依赖电子计算机来完成求最优模型解任务”;由于受计算量的限制,文章没有建立起按令级,加长调整期的具体模型,更没有对表示收获量调整结果由于条件不同有何特点加以分析。笔者认为,只按照未来的龄级分配做为条件进行收获调整是不够完善的,因此,本文试图从按令级、增加调整分期,并在目标函数中,考虑最大经济效益等方面提出一些探讨性的观点。为了了解模型的内在基本结
“East China Forestry Investigation Planning Intelligence” 1984 third period Comrade Zhou Shiqin linear programming theory has been used to adjust the amount of forest harvest made a preliminary analysis. However, as the article states, “When the variable Xi is increased, the iterative calculation can not achieve the goal by hand and we must rely on the electronic computer to complete the task of finding the optimal model.” Due to the limited amount of calculation, Order level, lengthen the adjustment period of the specific model, not to say that the results of harvest adjustments due to different conditions and what are the characteristics to be analyzed. In my opinion, only according to the future allocation of age as a condition for the adjustment of the harvest is not perfect enough, therefore, this article attempts to order from the stage, increase the adjustment of staging, and in the objective function, consider the maximum economic benefits, etc. to explore some of the the opinion of. In order to understand the model of the basic basic knot
