BEMTOOL è stato inizialmente messo a punto nel progetto MAREA
(MARE/2009/05-Lot 1; Specific contract n.4)
Aspetti generali della piattaforma BEMTOOL
Diverse flotte, diversi stock, interazioni
tecniche
MIXED FISHERIES
Aspetti biologici, di impatto e
socio-economici
Contesto multidimensionale
BEMTOOL - Approccio di simulazione
La condizione degli stock guida le misure di gestione, che sono
basate su attività e pattern di sfruttamento delle flotte…
Struttura della piattaforma BEMTOOL
in
componenti
È suddiviso
Modularità
Ogni modulo
 Biologico
 di Pressione (F, f, etc..)
 Economico
 Gestione/Harvest Rules
 Comportamento della flotta
 MultiCriteria Decision Analysis
Integrata con 6 moduli interconnessi
Moduli
BEMTOOL - componenti
I diversi moduli si articolano in componenti
•Effetti di selezione lunghezza/età specifici,
•scarti
•Performance economica a livello di fleet segment/metier
•Componente sociale
•Reference points
•Diverse misure di gestione
Il modello integra il possibile comportamento degli addetti, in termini
di investimenti o dis-investimenti, in risposta a cambiamenti nei profitti
(in assenza di specifici vincoli)
