NEW HEURISTIC FOR THREE DIMENSIONAL STRIP PACKING PROBLEMHa Thai Duong Supervisor: Edmund Burke, Graham Kendall

Overview Problem Definition Literature Review Currently Used Heuristic Tested Result Conclusion

Problem Definition Pack all boxes into a smallest open

container Min (Optimal Volume/Actual Volume)

Open Container

Boxes

Problem Definition Logistic

Container Storage

Cutting Material Space allocation

Problem Definition Dyckhoff (1990)

3/B/O/F, 3/B/O/M or 3/B/O/R 3: three-dimensional, B/O: one

object/container and selection of items, F: few items of different types, M: many items of many different types, R: many items of relatively few different types).

than search method Addition Constraints:

Orientation constraint Weight distribution Loading stability
