Welcome
Dear colleagues and friends, it has now been three years since we held the first Model-IT symposium on the opposite side of the globe in The Netherlands.
We felt it was time to organise a second edition of this modelling symposium ‘down under’ to show you the extreme sides of the world.
Given the positive response, there is still a clear need to meet and exchange ideas on developing models for the Agri-Food-Chain.
The challenge for these Model-IT symposia is to provide the necessary bridges, not only between the different research disciplines, ranging from biochemistry to engineering, but also between activities in the different parts of the Agri-Food-Chain from field to table, and between the different modelling approaches applied, ranging from deductive to inductive techniques.
This is been reflected by the contributions submitted to the symposium.
Model-IT 2001 will provide you with a platform to share your ideas, exchange your expertises, and trigger new alliances.
In addition, we took up the challenge to place you again into the shoes of students by organising workshops on different modelling aspects.
However, being learned students, we expect to see a large level of interaction between you and the workshop facilitators.
Again, we tried to have the proceedings available at the symposium, which became feasible thanks to your help and the help of Kelly Wilson and Tracey Upu with the type setting.
Though an immense effort, it will also give you the satisfaction not having to wait for months or even years to see the results of your work published.

The Princess and the doll
Pol Tijskens
Once upon a time, a magician with dolls made a very fine doll, with an alabaster face and with arms and legs that could move.
He put his skills in the making of the doll.
When he saw the results of his effort, he was proud of himself and he thought: “This is such a fine doll, with nice flexible arms and legs.
I will go and give it as a present to our princess, high up in the castle.”
He packed the doll in a fine wooden box, packed his clothes, packed something to eat and started on his journey to the castle.
When he arrived at the castle, he went to the princess, and said: “My beloved princess, I am the magician with dolls, and I made specially for you a nice doll with an alabaster face and arms and legs that can move”. The princess took the doll, and was very pleased with it.
For a couple of days.
But after a couple of days she thought: “This doll is not really very amusing.
She only has an alabaster face and arms and legs that can move.
I want another doll that can do more.
Then I will be pleased”.
And she called upon the doll magician and said: ”This is a nice doll with an alabaster face and arms and legs that can move.
But there is something missing.
I am no longer pleased with the doll”.
The magician was a little bit sad that the princess did no longer like his masterpiece doll.
He took the doll back to his magic workshop, and stared at it for a couple of days.
And he said to himself: ”Let me give her face a fair complexion, like the colour of our princess’s face, and make the doll so she can walk and move her arms herself”. And so he did in his magic workshop.
He put in the making of the doll more of his skills.
When he saw the results of his effort, he was very proud of himself and he thought: “This is such a fine doll that can walk and move her arms.
I will go and give it as a present to our princess, high up in the castle.”
He packed the doll in a fine wooden box, packed his clothes, packed something to eat and started again on his journey to the castle.
When he arrived at the castle, he went to the princess, and said: “My beloved princess, I made specially for you a nice doll with a fair complexion.
She can walk and move her arms herself”. The princess took the doll, and was very pleased with it.
For a couple of days.
But after a couple of days she thought: “This doll is not really very amusing.
She has only a fair complexion and she can move her arms and legs herself.
I want another doll that can do more.
Then I will be pleased”.
And she called upon the doll magician and said: ”This is a nice doll with a fair complexion that can move her arms and legs by herself.
But there is something missing.
I am no longer pleased with the doll”.
The magician was quite sad that the princess did no longer like his masterpiece doll.
He took the doll back to his magic workshop, and stared at it for a couple of day.
And he said to himself: ”Let me give her a voice of herself, so she can speak and think for herself”. And so he did in his magic workshop.
He put in the making of the doll all of skills.
When he saw the results of his effort, he was mighty proud of himself and he thought: “This is such a fine doll that can speak and think for herself.
I will go and give it as a present to our princess, high up in the castle.”
He packed the doll in a fine wooden box, packed his clothes, packed something to eat and started once more on his journey to the castle.
When he arrived at the castle, he went to the princess, and said: “My beloved princess, I made specially for you a nice doll that can speak and think for herself.
Now I am sure you will be pleased with my doll”. And the princess took the doll, and was indeed very pleased with it.
For a couple of days.
But after a couple of days the doll said to the princess: “You are just a princess, who cannot think for herself, and who is a nuisance for everybody around you.
I am no longer please with you.
I want to go back to my magician”.
And she called upon the doll magician, and went back with him to the magic doll shop and was happy with her magician for the rest of her life.
