A Case Study in Application of Vee Model of Systems Engineering to System Dynamics Modelling of Dryland Salinity in Australia

Abstract

This paper describes an application of the Vee Model of Systems Engineering in developing a System Dynamics model of dryland salinity in the Murray Darling Basin. A modular approach was adopted. Simple modules of salt affected land were developed using Powersim Studio following decomposition, definition, integration and verification processes. Individual modules were verified, integrated and provided with options for policy testing. The use of Vee Model provides a structured way for developing computer simulation model with a top-down approach for requirements elicitation and ensures that the computer model meets requirements and limitations elicited through qualitative System Dynamics and defined at the start of the modelling exercise. It also provides rigorous verification processes. The results of this research provide an avenue for further exploration of the synergistic use of the two approaches to improve model quality.
