Systems frecasting

Scientific prediction

Systems Forecasting is the personal consultancy of David Orrell. I am motivated by the belief that a systems approach to forecasting, which uses mathematical models, coupled with other techniques such as scenario planning, can be used to leverage existing data, make predictions, and help prepare for the future. Current projects include predicting the effects of anti-cancer drug schedules with Physiomics, and transportation forecasting with PTV NuStats.
