Philosophy and terminologySince the 1950s, engineers have paid much attention to the study of complex, dynamic systems. Their successes inspired biologists to apply similar techniques in their disciplines. The approach is characterized by the terms: system, model and simulation.

A simulation language: Continuous System Modeling Program IIICSMP stands for Continuous System Modeling Program, version III. It has been extensively described in the Program Reference Manual by IBM Corporation, 1975. In this chapter only the essentials of CSMP will be discussed. However, these essentials enable us to solve many problems.

Mass flow, numerical dispersion and diffusionibuted around the 20. day. The shape of the cumulative curve of germinated seeds versus time, will be similar to the breakthrough curve. (Compare for example the curves in Figure 8.8.) The distribution of the germination periods can, in principle, be explained by variation in the ambient conditions
