Development of heuristic methods for cutting pattern sequencing has the objectives of:

  • Minimizing the number of pallets required by a sequence
  • Minimizing the dispersion/spread index of orders across cutting patterns
  • Improving the material handling systems in order to minimize the overall order completion time
  • Metaheuristic methods as tabu search and genetic algorithms to quickly find “good” solutions

Integrating cutting stock and pattern sequencing methods through:

  • Developing heuristic methods for trim loss problems with constraints on material loading and handling
  • Limited local buffer capacities
  • Limited availability of pallets
  • Limited waiting times in the loading zone
  • Limiting the usable cutting patterns
  • Subgroup strategies
