"The aim of the present paper is to illustrate how extremely complex patterns may be generated in a simple model of educational planning. In particular, we will show that certain dependencies of the flow rates on the teacher/student ratio imply nonlinearities which are substantial enough to generate erratic behaviour of the time paths. The main message is that chaos in educational planning may result from assumptions which are indeed qualitatively realistic but which are quantitatively exaggerated." (SUMMARY IN FRE)

依赖存量的流量如何暗示教育规划中的混乱

“本文的目的是说明如何在一个简单的教育规划模型中生成极其复杂的模式。特别是，我们将证明流量对教师/学生比例的某些依赖性意味着足够大的非线性以产生时间路径的不稳定行为。主要信息是教育规划中的混乱可能是由于假设确实在定性上现实但在定量上被夸大了。” （免费摘要）
