DOME Pro – Decision Optimization & Modeling Environment

What — A decision analytics platform for evaluating real property investment options: as many options as a decision requires, with results viewed simultaneously. Delivered as an Excel add-in built on Office.js.

Why — Options are only meaningful when they are modelled on the same basis, over the same horizon, against the same assumptions. DOME™ holds that discipline.

How — Discounted cash flow analysis, option evaluation, sensitivity testing and Monte Carlo risk simulation, across capital, revenue, accommodations, GHG emissions and risk:

• Set your own escalation and discount rates, energy and GHG inputs, horizon dates, fees and risk variables.
• Add as many accommodations per option as needed: owned, leased or P3, with terms and rates.
• Place each capital expenditure in its horizon year with the escalator you choose.
• Capture one-time revenue, from opportunity cost to residual values.
• Run a Monte Carlo risk simulation for each option and compare the results side by side.

DOME™ evaluates the decision. ARCH™ manages what follows, because a recommendation still has to survive the funding process behind it.
