Uncertainties in OSMOSE model

Dear Sir/Ma'am,
Recently we came across a document (ftp://ftp.fao.org/docrep/fao/010/a1149e/a1149e.pdf, Page 106) where it highlights about the uncertainties in OSMOSE model stucture/parameters/data. We have the following query regarding the same:
Is there a way for the end-user to deal with uncertainties associated with OSMOSE? Could you share your insights about how we can quantify these uncertainities especially when it comes to interpreting the model results?
We look forward to your response regarding the same.
Kind regards,
Tarun Joseph.
