A control system project development model derived from System Dynamics

This paper examines established Systems Dynamics (SD) models of projects in order to simplify them. These models are highly non-linear and contain large numbers of variables, with built in decisions using empirical data. A SIMULINK version of an SD model was created and conclusions are made with respect to the main controlling factors, compared to a NASA project. Stages in simplification are described leading to a control system model. This model is then used to develop criteria to judge stability, controllability and observability of projects with use for practical decisions by project managers. All the models and the NASA data are compared to allow the reader to judge the efficacy of the simulation. The developed model is then compared with another project solution.
