DecisionTools Suite 8.9 is the complete Excel-based risk and decision-analytics bundle: seven complementary tools that turn spreadsheets into full quantitative analysis environments. Whether you are modelling reservoir uncertainty, optimizing well-completion designs, or building decision trees for capital investment, this Suite gives you the full toolkit in one installation – Industrial edition, no size limits on models or iterations.
What’s Inside – 7 Complete Tools
@RISK – Monte Carlo simulation. Replace uncertain single-point estimates with 90+ probability distributions; run thousands of iterations to reveal every possible outcome and its likelihood.
PrecisionTree – Decision-tree analysis. Model sequential decisions and chance events graphically, then compute expected value, risk profile, and the optimal strategy.
TopRank – Automated what-if / sensitivity analysis. Instantly find which model inputs matter most, without writing a single formula.
