The article discusses some statistical techniques applied as confirmatory tools to the System Dynamics modelling and analysis of Blood Bank Inventory Management systems. Instead of using arbitrary means, problem definition and statements are corroborated with statistical mehods of correlation and formulation of adjacency matrices. This is extended to the estimation of some of the parameters of the system. Numerical Performance Measures (NPM) used to evaluate the system response to various inputs are discussed. The response of the system is illustrated primarily as time series plots. System trajectories or phase plane plots are presented with statistical inferences in relation to the model. It is concluded that for SD model refinement and analysis statistical techniques can be used judiciously as a confirmatory tool in unison with judgmental evaluation of the system.
