| چکیده [English] | ||
| In the 17th issue of the Management Knowledge the first part of this article was published which dealt mainly with four part hierarchical model such as closed boundry, feedback loop, status variables and rate variables. In this part the phases of Systems Dynamics studies have been explained, these pahses are: 1.Conceptual. phase, 2. Quantitative phase, 3. Analysis & Evaluative phase. At the conceptual phase the backgrounds and Symptoms of the problem has been explained: * The behavior of the major variables has been designed and the objective of modeling has been cleared. The conceptual phase of modeling in a sense is the skeleton and comperehensive framework of a model in the context of a simple dinamic hypothesis. *, The behavior of the main variables is studied within the context of past, existing and desired ones which have been manifested under the execution of different policies. * At the quantitative phase the skeleton and the general framework of the model which has been designed would be drifted to ward the real phenomenon. With the determination of type and quantity of one of the variables and parameters of the problem, the model would be built and executed upon• through utilization of simulation soft-ware called Dynamo. * At the analysis and evaluation phase, the dynamic hypothesis after quantitative planning and computer execution, would be turned back again to the conceptual phase and tested through testing and evaluation. Along the article the cause/effect relationship with examples has been explained. | ||
