Analytica was designed from the start to combine several key decision-technologies into fully integrated, easy-to-use package. They include: 

  • Visual influence diagrams to define and organize complex models into comprehensible modules.
  • Intelligent arrays™ to make it easy to manage models with multiple dimensions.
  • Monte Carlo simulation to analyze uncertainty and risk with speed and simplicity
  • Optimization, including linear and nonlinear programming.

The technology underlying Analytica is based on a decade of research by decision analysts, computer scientists, and user-interface designers at Carnegie Mellon University, with support from the National Science Foundation.

See below for more details on each technology:

Simple influence diagram


An influence diagram is an intuitive visual display of a decision problem. It depicts the key elements, including decisions, uncertainties, and objectives, and how they influence each other. »more


Monte Carlo simulation is a simple and efficient way to represent and analyze risk and uncertainty. It generates a random sample of values from each input probability distribution and a corresponding sample… »more


The spreadsheet was the first "killer app", the application which led to millions of people buying their first personal computers in the early 1980s. Spreadsheets were a brilliant innovation… »more


  Whether you are developing strategic plans or making day-to-day decisions, you often need to use estimates made by others.  We are all aware that nearly every estimate is laced with uncertainties,… »more
