**6. Conclusions**

This study found that the purpose of uncertainty analysis, and sensitivity analysis is to determine the potential directions for waste management decision support systems under uncertainty, because this technique accounts for uncertainties in the assumptions, and to introduce the sensitivity analysis

Because all of the parameters of the economic model are independent, the using of the SRC is shown to be extremely satisfactory.

Cost risk analysis can answer some questions that the traditional estimating method cannot. Included are:


Uncertainty reduction in the project is performed during the planning phase of the project using the software package SimLab® for project risk management.

In summary, integrating risk analysis into waste to energy pyrolysis facility project management processes may be useful for the project managers. In this study the most likely Total Project Cost values are about 2.53563E+007 USD and 2.663226E+007 USD for the analyzed Scenario. Every manager has a different degree of aversion to risk.
