AI-GEOSTATS: weighted Voronoi diagrams
- Dear List Members,
My name is Armando B. Mendes and I�m a PhD student at Technical University
in Lisbon, Portugal.
I�m analysing a problem related to forecast annual sales for food retail
In order to include demographical variables in my descriptive models I must
delimitate retail trade areas around shops.
I tried various methods and the more promising one looks like Voronoi
diagrams. Therefore, I must include store attractivity in de diagram so I�m
using weighted tessellations. But, the retail trade areas obtained look to
me too small.
So, based in the book by Atsuyuki Okabe �Spatial tessellations : concepts
and applications of Voronoi diagrams� I would like to try second order
weighted diagrams, i.e., diagrams in which the costumers frequent
simultaneously two nearby shops (or any tessellation is generated for 2
points simultaneously the near one and the second near one).
So, my question is do you know of someone who had developed any software to
calculate second-order Voronoi weighted diagrams? I would be very thankful
for any answer.
