Testing Methods on System Dynamics: A Model of Reliability, Average Reliability, and Demand of Service

As a model used to simulate policies by creating scenarios, system dynamics must have similarities with real systems. Therefore, the system dynamics model should test so declare as the right model and representing the behaviour of a system. Thus, in this article, we propose three test methods to ensure the system dynamics model have appropriate structure, correct value according to the specified equation, and can use to establish the parameter of the model. We study articles to propose the testing methods (the structural testing, algorithms testing, and behavioural testing) and present the case study about reliability, average reliability, and its affected demands. In this article, we prove that the testing methods can be used to show the system dynamics model appropriates and represents the real system, all computation generated by the simulation output is proper to the specified equation and can use to choose the best parameter.
