Application of FLR• Generic

• Functions from Theory

• Key parameters (theory): q,x,shadow value,enf. cost, prob fine,f

• Case study specific

3

Team

• CEFAS: “architecture” and documentation

• IC: modules for calculating new functions (penalty prob.; enforcement cost)

• AZTI: links FLR to databases

• JRC: testing solutions for less experienced users (web access version)

4

• Requirement for development of generic code• Implement COBECOS theoretical approach on a

case-study basis• Each case-study has individual requirements• Guidance can be provided• Use simple relationships versus complex (MSE) –

depends on resources, data, linkages to other projects.

• Code for computation of (Fbiol, FLEcon)?– Derive – Monte carlo

• Other functions? (regressions etc)

• Within case study: resources required! (dedication of participants – at case study level)

• Workshop (FLR – one day at IC September)
