摘要：The purpose of this artcle is the analysis of the system dynamics model validaton illustrated by the example of a model of the manufacturing resource allocaton. In the frst part of the artcle the authors present an overview of the defnitons of validaton and verifcaton that can be found in the reference literature. Also, they emphasize the role which validaton and verifcaton play in the modeling process. Furthermore, they discuss the techniques of system dynamics model validaton with partcular focus on tests of the model structure, behavior and policy implicatons. The second part of the artcle contains an example of the validaton process of a system dynamics model simulatng manufacturing resource allocaton in an electronic company. The purpose of the model is to assess the long-term effect of assigning workers to individual tasks on such producton process parameters as efciency or effectve work tme. The authors focus their partcular atenton on that part of the model which deals with a storehouse, one of the company producton units. They conduct tests of its structure and behavior. When validatng the structure the authors make use of the informaton obtained in a series of interviews with the company staff. They also refer to the generally accepted knowledge found in the reference literature. The results generated by the model in the course of the behavior tests are compared with the real data. The authors evaluate both the logic of the system behavior and the level of accuracy of the output data in reference to the real system.
