What is “Process Simulation”?
Q: What does the word “simulate” mean?
Building a process model Predicting how a process would actually behave Performing an experiment (on computer)
Incentives: Highly cost effective Reasonably accurate Proactive approach
IDEA GENERATIONProject Screening, Strategic Planning

The Role of Process Simulation and Scheduling Tools inProduct Development and Commercialization
Sequential modular approachSequential modular approach Individual equipment blocks may require
iterative solution algorithms
Overall process solution is sequential & not iterative
