An Analytica model is organized as a hierarchy of influence diagrams. They show you the big picture and let you build and navigate your model visually. Think of this as an interactive whiteboard—but with all the details, calculations, and numbers underneath.

**Drill down, up or sideways.** Analytica’s influence diagrams are your model’s visual roadmap. With a hierarchy of nested modules, you always know where you are and can quickly move to any desired level or module.

**Build, navigate, present and explain your
model’s structure with speed and confidence.** Never again hunt down and decipher arcane row-and-column coordinates or formulas. Dispense with building separate summary models and reports in order to present and support your results. Your Analytica model is all you need.

“With a little practice, you can link elements to build a model almost as fast as you can think.”

—MacWorld

“An Analytica diagram is worth a thousand spreadsheet cells.”

—Rich Brenner, The Brenner Group LLC

“My sincere congratulations for the development of a very fine program. I really like it. It is very easy to use when setting up models and especially in modifying them.”

—Naval Postgraduate School

“Analytica is very easy to learn. ... Once the software has been learned, it is delightful to use. The number of mouse-clicks and key strokes required to produce desired results is minimal, yet the process to follow is obvious.”

—Cox & Associates

“Analytica makes an excellent replacement for a spreadsheet since models can be constructed directly from relationships without being constrained by the row and column paradigm of a spreadsheet.”

—David Neiger, Australian Engineer magazine

“I estimate that the time I spend writing Analytica models is one quarter to one half of that devoted to similarly complex spreadsheets.”

—ORMS Today

Although the influence diagram appears as simple, it scales up to handle complex, multidimensional problems—effortlessly. Don’t worry about the rows-and-columns layout of your model. You create, change, or extent dimension, and Analytica cares about the rest.

**Forget about the rows-and-column restriction of Excel.** Analytica’s proprietary Intelligent Arrays™ provide the power to scale up your models to handle multidimensional problems with ease—for instance, sales over many time periods, products, and regions, as a function of alternative prices and marketing budgets. Each dimension becomes a simple index.

- Write and store each formula only once, not one for each cell in a table.
- Choose the most meaningful views in tables and graphs by interchanging rows, columns, and higher dimensions.
- Extend existing dimensions or add new ones—the model expands automatically without the manual work required with Excel.
- Reduce the time and effort to build, verify, and audit large models at an order of magnitude.

“Analytica is like a multidimensional spreadsheet, only much friendlier.”

“Development using other tools would have been a lot slower and provided less capability. The way Analytica handles multidimensional arrays is a huge advantage over spreadsheets. We are so pleased with Analytica that we're recommending it for several other major projects at Bechtel SAIC.”

—Jim Nail, Project Leader, Bechtel SAIC, LLC

“What had taken 39 spreadsheet workbooks and 9MB of disk space was now in one Analytica file, all of which takes up less than 100KB. This simulation intensive model took over 5 hours to run in spreadsheet form but only 1 1/2 hours with Analytica.”

You can easily replace any variable in your model by a probability distribution. Analytica generates sample values based on this and let you see and analyze the effects on every “downstream” variable in the model. With no special statistical expertise required.

Risk and uncertainty are facts of life, which are more easily managed with Analytica. Understand and manage uncertainty explicitly, using probabilities—without requiring special statistical expertise:

- Express uncertainty by selecting the appropriate probability distribution in Analytica’s graphical browser.
- Propagate uncertainties throughout your model—with ease and efficiency—using Latin Hypercube or Monte Carlo sampling.
- Display uncertain results in any form: as probability bands around the median, probability density functions, cumulative probability functions, or standard statistics.

“We also liked the way we could use probability distributions to be explicit about uncertainties. It can flexibly display simple point estimates or entire probability density plots, according to the interest of the user.”

—Eric Pan, MD., Center for Information Technology Leadership, Boston, Massachusetts

“Once clients see the effects of uncertainty on payback and profit illustrated graphically as Analytica models, they become much less intimidated by the data, and ultimately, more profitable decision makers.”

—Robert Brown, Partner, Decision Strategies, Inc.

“Analytica beats other decision analysis software packages we have used hands down as a general purpose decision modeling tool.”

—Tony Cox, Cox and Associates

“The Last Word: If you have any professional responsibility for decisions involving money, buy Analytica and learn to use it. Once you understand Analytica modeling, you'll see why common spreadsheet single-number predictions in business are so often useless and misleading.”

—Charles Seiter, MacWorld
