PRELIMINARY STUDY OF THE APPLICATION OF PARAMETRIC LINEAR PROGRAMMING IN FORMULATION OF SUBSTRATE MIXES
The present work shows that parametric linear programming of separate materials could be used to shorten steps, leading to selection of substrate mixtures (selection a priori).
6 substrate mixes were obtained in this way from characteristics (physical and chemical properties and processing) of 9 original materials and establishing the margin of the characteristics of the desired mix. The 6 selected substrates were reconstructed from the proportions of the separate materials obtained by linear programming.
Comparing experimental and theoretical values for the defined properties of the substrate, in all the mixes linearity was achieved to an acceptable extent in parameters such as BD, TPS, AC, EAW, and WBC; therefore, linear programming can be useful as a first approximation to a definite mix.
