Sequencing jobs on a bottleneck machine

Description
Sequencing jobs on a bottleneck machine: consecutive solving with 3 different objectives;
  • linear and 'element' constraints; branching strategy for variables (b4seq_ka.mos).
  • Alternative formulation using 'disjunctive' constraint, branching over variables and constraints (b4seq2_ka.mos).
  • Third formulation as disjunctive scheduling / sequencing problem, modeled with task and resource objects (b4seq3_ka.mos).
Further explanation of this example: 'Xpress Kalis User Guide', Section 3.5 element: Sequencing jobs on a single machine
