01
PROJECT INPUT
Project inputs
Country, capacity, stage, product mix, operating regime and known constraints.
SIGMAPROFESSIONAL ENGINEERING TOOLS
Calculations that continue the project instead of ending with a number.
The historical 20,000–500,000 m³/year corpus becomes a controlled digital product: inputs → assumptions → calculation → saved result → engineering action.
02
ASSUMPTIONS
Engineering assumptions
Raw materials, utilities, process configuration and validation state.
03
ENGINE
Calculation engine
Validated server-side logic; proprietary formulas stay outside the client frontend.
04
RESULT
Result
Capacity, resources, CAPEX/OPEX framework and permitted outputs.
05
SAVE
Project and version
Saved project record, assumptions, version and documents.
06
ACTION
Next step
Engineering review, C-910, configuration or RFQ.
VALIDATION GUARD
Historical formulas do not automatically become production logic.
All legacy coefficients and numeric assumptions remain SOURCE CLAIM until engineering validation.
Normalized project data
Engineering rules / evidence
Server-side logic
Saved assumptions + result
