WHAT IS THE DECISION TREE?
Decision tree is a decision support tool that uses a tree-like graph or model of decisions and their possible consequences, including chance event outcomes, resource costs, and utility.
Decision tree is commonly used in operations research, specifically in decision analysis, to help identify a strategy most likely to reach a goal.
Another use of decision trees is as a descriptive means for calculating conditional probabilities.

THE ADVANTAGE OF DECISION TREE Are simple to understand and interpret. Have value even with little hard data. Use a white box model. Can be combined with other decision techniques.

METHODOLOGY Identifying the work packages for risk analysis. Identifying the factors that affect the time, cost, and
quality achievement of a specific work package. Analysis the effect and determining severity of
failure Driving various alternatives responses for mitigating
the effect of risk factors. Estimating cost for each alternative Determining the probability and severity of failure of
a specific work package Forming a decision tree. Deriving expected monetary value or the cost of risk
response in this case. Selecting the best option statistical analysis.

CONCLUSION
Risk management using a combined AHP and DTA provides an effective means for managing a complex project efficiently.
Risk management makes an effect to quantify risk by modeling its probability and severity in line with the perceptions of experienced project executives subjectivity.
