System dynamics methodology has been used in many fields of study which include supply chain, project management and performance, and procurement process. The said methodology enables the researchers to identify and study the impact of the variables or factors on the outcome of the model they developed. In this paper, we showed the use of system dynamics methodology in studying the behavior of procurement process that is totally different from those mentioned in previous studies. By using a typical procurement process employed by a telecommunication company as a case study, we proposed a new one (i.e., procurement process) and developed a procurement model where we discovered that the number of days involved in completing the whole procurement process depends heavily upon the scenarios we created (especially those that exceed two months), and suggested future research undertakings.

用系统动力学方法描述的采购过程行为

系统动力学方法已用于许多研究领域，包括供应链，项目管理和绩效以及采购过程。所述方法使研究人员能够识别和研究变量或因素对他们开发的模型结果的影响。在本文中，我们展示了使用系统动力学方法来研究采购过程的行为，这与以前的研究完全不同。通过使用电信公司采用的典型采购流程作为案例研究，我们提出了一个新的流程（即采购流程），并开发了一种采购模型，在该模型中，我们发现完成整个采购过程涉及的天数在很大程度上取决于我们创建的方案（尤其是超过两个月的方案），
