基于Logistic 增长曲线模型的大学在校学生数量发展预测 彭怀祖 （南通大学，江苏南通226007）摘要：由1983-2009年高等教育在校学生数的增长趋势图可以发现，我国高等教育规模发展表现为一种“S ”形增长，为此构建logistic 增长曲线模型，并结合1983-2009年数据对未来10年我国高等教育在校学生数进行预测。预测结果略高于《...
The logistic growth definition in population models refers to the gradual growth of the population in the beginning and then increases when the number of people grows. When does logistic growth occur? According to the logistic growth model, the population grows the most when a high number of peo...
In this paper, we develop a four-parameter generalization of the logistic growth curve, the flexible-logistic (FLOG) model. It is shown that the FLOG model is sufficiently general to locate its point of inflection anywhere between its upper and lower bounds: it can offer wide variation in ...

5. Logistic Growth Curve: When plotted on a graph with population density against time, the logistic growth model produces an S-shaped curve, which illustrates the three phases of growth: lag, log (exponential), and stationary. SummaryLogistic growth is a model that describes how populations gro...
Notwithstanding this limitation the logistic growth equation has been used to model many diverse biological systems. Carlson [2] reported the growth of yeast which is modelled well by the curve [3], [4]. Morgan [5] ingeniously used the equation to describe herding behaviour of African elephants...

Notice that the graph looks a lot like the exponential model we created in the last section for fish population until about 15 years out. Then the curve begins to flatten. Examples A forest is currently home to a population of 200 rabbits. The forest is estimated to be able to sustain a...
