Project on Decision Analysis: Singapore Fifth NEWater Plant

This project analyzes the Singapore Fifth NEWater Plant using decision analysis techniques. It begins with a problem statement highlighting the importance of water conservation and the challenges of water scarcity, setting the objectives to evaluate the project's viability. The project outlines the construction of the fifth NEWater plant at Changi, a key component of Singapore's water management strategy. The analysis involves creating a decision tree to model the project's potential outcomes, along with an expected value analysis to assess different decision paths. Risk profiles are developed to identify and quantify uncertainties associated with the project, and the exploration of key uncertainties considers factors such as technological risks, cost overruns, and demand fluctuations. The project also examines trade-offs between multiple objectives, such as cost, environmental impact, and water quality, while addressing attitudes toward risk. The project concludes with recommendations based on the decision analysis, offering insights into the project's potential benefits and drawbacks. The project utilizes only publicly available information to simulate a consultant's perspective before the decision was made.
