This site contains material developed for the
ECASA project by William
Silvert. Most of it deals with the possible use of a Decision Support System
(DSS) for aquaculture site selection. Here is a listing of material available
(note that the project is over and this material is not all up-to-date, and some
example programs may not work correctly):
This site is being updated in 2010 since many of these
programs have been updated or replaced by more recent work on DSS that can be
found in http://bill.silvert.org/DSS.
The ECASA project ended in 2007.
- A non-working DSS prototype showing the kind of interface that might be
appropriate. This no longer functions correctly, but the first part of it
may be interesting. Only the first couple of pages of
this demonstration have been retained.
- A link to the site
http://silvert.somee.com/ which has a very simple web-based DSS (this site
is no longer accessible).
- A downloadable DSS program based on the CSTT model
of Paul Tett and colleagues which is used to predict eutrophication effects
of fish farms. (This program requires the .NET framework)
Now updated and available at the
new DSS site.
- Another downloadable DSS prototype for shellfish
siting. This is a preliminary version and the parameter values and
conversion factors need to be corrected, but the general structure of the
program illustrates the basic idea, which was originally proposed by
McKindsey, C. W., H. Thetmeyer, T. Landry and W. Silvert. 2006.
Review of recent carrying capacity models for
bivalve culture and recommendations for research and management.
Aquaculture 261: 451–462, and incorporates some ideas of Aad Smaal of IMARES
Yerseke. Keep in mind that this version is being developed and may still
have some bugs as well as incorrect parameter values - it was last updated
on 12 December 2007. (This program requires the .NET framework)
Now updated and available at the
new DSS site.
- Several supporting documents in Adobe PDF form:
- A set of papers was prepared for my ECASA colleagues in April 2007 which
deals with the question of when to use fuzzy logic and the process of
developing Expert Systems and Decision Support Systems which use fuzzy
logic. This is a fairly technical set of reports which addresses issues that
ECASA has been dealing with (namely sustainable aquaculture in the EU), but
may be of interest to others working in the field. The Fuzzy Modelling Package is a ZIP archive of
MS Word files, which are as follows:
