Value of Control


About the Skill Module

This skill module introduces value of control and covers the following topics:

  • Decision Trees – Expanded: Decision trees are the most recognizable feature of decision analysis. So, many people think these are synonymous.
  • Value of Control I: Investing to reduce project and operations risk are typical value of control (VOC) problems. Improving "control" means taking action to improve the probability and/or outcomes of a chance event.
  • Value of Control II: An oil tanker has a heightened risk of collision accidents and oil spills if it loses its steering or propulsion power system. This exercise is to develop a decision model to decide whether to spend additional money on maintaining the tanker's steering and propulsion systems.
