CDEPD-class: Class '"CDEPD"'

Description Objects from the Class Slots Methods Author(s) See Also Examples

Description

Class for the definition of the Deterministic Equivalent Problem

Objects from the Class

Objects can be created by calls of the form new("CDEPD", ...), or more conveniently by the generator function DEP().

Slots

MP:

"CLPD": The master or first-stage LP.

q:

"matrix": The objective(s) in the second-stage (per row for each scenario).

W:

"matrix": The recourse-matrix.

h:

"matrix": The absolute values of the rhs-constraints (per row for each scenario).

Tech:

"list": The technology matrices combined in a list object.

SubDir:

"character": The relational operators to be used in the second stage.

prob:

"vector": The probability for each scenario.

K:

"integer": The count of scenarios.
