The proposed model was implemented using AgenaRisk toolset [1]. AgenaRisk is a powerful tool for modelling risk and making predictions based on Bayesian Network. AgenaRisk has the following features:

• It integrates the advantages of Bayesian Networks, statistical simulation and spreadsheet analysis.

• A wide range of built-in conditional probability functions are available.

• It has the ability to build dynamic models.

• AgenaRisk is visual, simple and powerful tool.

A free licence for AgenaRisk toolset is available through the company website (http://www.agenarisk.com), but limited to 7 days.

In the next section, experiments setup will be illustrated, while the results will be provided and discussed in the following section
