Abstract
Super-projects are built by investing large amounts of money, time and manpower. These irreversible projects have a profound impact on the market price and are very difficult to manage because the definition of objectives by decision makers at each level of the super-project is so different. In this paper, the author tries to develop an optimization model which is based on cost-benefit-analysis and risk-analysis for super-project decision makers on procurement management with due consideration of the hierarchical organization of the construction industry.
