Flow Modelling of the Educational System Using Dynamo Method
This article proposes to model and identify the educational system using modelling dynamo in the stock-flow approach initiated by Forrester. The method is to model a level of schooling and determine its step and impulse responses. Model of one cycle is obtained by cascading levels which make it up. The system model is obtained by the cascading of the cycles which make up. For analyzing the impulse response of a school level, a known number of students is injected into the corresponding tank as initial value. The simulation process allows seeing how the level of the tank evolves with respect to time. During this simulation, Inflow is maintained disabled. For the step response is the inflow which is maintained at a constant value. Tank is initially empty. The flow parameters used in modelling are: the promotion rate, repetition rate, and dropout rate. In reality, these parameters depend on time and on some other factors. To simplify the analysis and identification, it's the average values of these parameters that are taken in the simulation process. After cascading, the overall model allows to visualize the response of the system in respect of different values of the flow parameters, so that makes it possible to explore by simulation the behaviour of the system in response to a given policy decision.
