GrafCompounder Tutorial and Literature

Program Description

GrafCompounder is a software, which enables you to create recipes for Rubber, TPE, TP and other compounds from an unorganized recipe & property database.

A multiple linear iteration method [MLI] is used by the GrafCompounder to calculate a compound recipe.

The GrafCompounder enables you to analyze your database and identify faulty compound data, because it allows you to identify each compound recipe and its ratio your calculated compound is composed off. This program feature is extremly helpful, if your confirmation experiment will result a difference with the compound properties calculated larger than the 95% confindence interval.

With a database, which has a sufficient high amount of compounds, you are able to use the GrafCompounder like a compound simulation tool.

The latest Version 2.004 has features, which are explained in datail in its tutorial. The program allows to store the data in its own file format: ____.gc, but the export in a table calculation program is possible as well via copy & paste.
Two new columns are added in the working screen of the program:

  • The first column shows the minimum values of each row, whether it is an ingredient or property,
  • the second column shows the maximum value in each row.
This information prevent a calculation, which is not supported by the database.
The figure below shows a screen shot of the Grafcompounder 2.004 with a recipe dataset in the left screen, the "criteria" window with the maximum and minimum columns and in the "output" window a sample recipe calculation according to the performance criteria shown.

Minimum hardware and software requirements

The GrafCompounder software runs on Windows® XP or Windows® Vista with at least 512 MB RAM.

With Windows® 7 / Windows® 8 / Windows® 10 at least 1 GB RAM is needed.

Literature / Presentations

For the first time a whole design of experiment [DoE] is simulated with the GrafCompounder Software. The results are published at the Tire Tech 2015, 10.-12. February 2015 in Cologne under the title: CARD - Computer Aided Recipe Development in the session: "Smart Tire Factory."
A second publication is printed in RFP 04/2016 under the title:
Simulation of a statistical experimental design with a new solftware tool.
