## EconMult

EconMult is a meta-model where structural variables define the resolutions of an infinite number of potential models. Structural variables are set by the command EMsetup. When no arguments are provided, the default values of the structural variables are used.

In addition EconMult includes PopulationGrowth, a package including standard population models.

EconMult is a meta-model where structural variables define the resolutions of potential models. Structural variables are set by the command EMsetup. When no arguments are provided, the default values of the structural variables are used.

EMsetup[]

No biomass vector was found. Assuming single value
No fleet vector was found. Assuming single value
No period interval was found. Assuming single value

EconMult structure:
1 targeted species (pEMtargetedSpecies)
1 biounit (EMrelatedBioUnits)
1 fleet group (pEMfleetUnits)
1 simulation period per year (EMinterval)

The structural variables are given above by the three parameter values EMrelatedBioUnits, pEMfleetUnits and EMinterval.

EMrelatedBioUnits
{{1}}

and

pEMfleetUnits
1

and

EMinterval
1

and

pEMtargetedSpecies
1

Let us try another resolution

EMsetup[{{1, 2}, {3}}, 2, 4]

EconMult structure:
2 targeted species (pEMtargetedSpecies)
3 biounits (EMrelatedBioUnits)
2 fleet groups (pEMfleetUnits)
4 simulation periods per year (EMinterval)

Let us find the catch of the first period
