TEA

Process Economics Decision Model

Named deliverable Objective-Function TEA Model

We start with the decision, the process boundary, and the resource that matters most. That may be money, mass, energy, water, yield, throughput, or another constraint. I build the material and operating logic from the evidence available, keep the assumptions visible, and test how the answer moves when those assumptions change. The model shows what drives the decision and what data would make it more reliable.

What you get

  • A written decision question and system boundary
  • The objective function and comparison cases
  • Process-flow and material-balance logic at the maturity the evidence supports
  • An assumption and source register
  • Cost, mass, energy, yield, or throughput inputs relevant to the decision
  • Sensitivity and scenario analysis
  • A model the client can inspect and update
  • A list of the assumptions most likely to reverse the conclusion
  • A continue, compare further, gather data, change the process, or stop decision memo

Who it's for

Founders and R&D leaders comparing technical routes, funding a pilot, changing a system boundary, or deciding what data to gather next
