A tableau for use in the Simplex method.
Example:
W | Z | x1 | x2 | x- | s1 | s2 | a1 | RHS --------------------------------------------------- -1 0 0 0 0 0 0 1 0 <= phase 1 objective 0 1 -15 -10 0 0 0 0 0 <= phase 2 objective 0 0 1 0 0 1 0 0 2 <= constraint 1 0 0 0 1 0 0 1 0 3 <= constraint 2 0 0 1 1 0 0 0 1 4 <= constraint 3
W: Phase 1 objective function Z: Phase 2 objective function x1 & x2: Decision variables x-: Extra decision variable to allow for negative values s1 & s2: Slack/Surplus variables a1: Artificial variable RHS: Right hand side
