Where are we going? The use of the Trends Integrator Procedure (TIP) for scenario generation

The Trends Integrator Procedure (TIP) is a simplified systems dynamics model for examining the interactions between sets of factors (e.g. land use, environment, congestion, population, transport, energy usage, etc.) over a defined time period (usually some years). TIP may be used to build personal of ‘eclectic’ models for use in scenario generation, problem resolution, policy formulation and decision-making. It provides a comprehensive approach to impact prediction in dynamic system with inter-realted factors and trends. The approach may be termed ‘indicative’, yielding results that are ‘roughly right, not precisely wrong’.
