Mixture Process Design is intended for experiments where the user is interested in the influence of varied dependent variables, materials (weight or volume percentage of each material) and processing steps, on target properties.
Mixture Process Design in Alchemy
Mixture process design in Alchemy is automatically proposed when the user inputs wt% or vol% for each material and total batch size which will be equal for all experiments from the design and processing steps.
Constraints
Required constraints for each material are:
- Lower and upper bound for varied materials
- Constant for non-varied materials (influence of this materials cannot be assessed)
Required constraints for each condition from processing step are:
- Lower and upper bound for conditions of number type
- Any of for conditions of predefined number or text (alphanumeric) type
- Set to for conditions of predefined number or text (alphanumeric) type which are not varied and
- Constant for non varied conditions (influence of this conditions of processing steps cannot be assessed)
Rules for Valid Constraints
Rules which need to be respected for properly setting the constraints:
- Sum of all lower bounds and constant materials should be lower than 100%
- Sum of all higher bounds and constant materials should be higher than 100%
