- With dependent contingencies, "low" probability events may not be so "low" probability after all.

- The methodology for solving the multi-attribute, multi-year capital budgeting problem is well-developed and available in the public domain. The recognized expert in multi-attribute decision theory is R. Keeney (see R. Keeney, Value Focused Thinking: A Path to Creative Decisionmaking). Applications of the methodology to electric utility capital budgeting are becoming more common. See, e.g., L. Merkhofer on Priority Systems. Lee Merkhofer, 2003, and S. Chapel, et al., Project Prioritization System: Methodology Summary, EPRI 2001. Both papers can be downloaded from the publications page of www.s-chapel.com.
