NEW HEURISTIC FOR THREE DIMENSIONAL STRIP PACKING PROBLEM Ha 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). Wascher et al. (2007) Three-dimensional cuboids open-dimension-problem

Literature Review Each heuristic suitable for some cases Constructive heuristic is more important than search method Addition Constraints: Orientation constraint Weight distribution Loading stability
Currently Used Heuristic Max Surround Touching Min Rotation Score Min Volume Percentage Max Contact Area & Max Volume (S. Allen E. K. Burke G. Kendall)
Max Surround Touching Touching top of the box
Max Surround Touching
Touching top of the box
Min Rotation Score Box with less rotation is harder to pack Packing box with min rotation score Rotation Score (Number Possible Rotation * Number Box)/ Total Number Box
Min Rotation Score No Rotation
Min Rotation Score No Rotation
Min Rotation Score No Rotation
Min Rotation Score No Rotation
Min Rotation Score No Rotation
Min Volume Percentage Optimal Volume/ Actual Volume
Min Volume Percentage
Tested Result BR dataset – OR Library BR10 – 87.2% (Best 87.6) Viewer created by Sam Allen
Conclusion & Future Work New heuristic particular good in some cases Multiple heuristic run Different data set Application hyper-heuristic
