Cylinder packing efficiency

WebMay 27, 2016 · 16 Citations Metrics Abstract The paper considers an optimization problem of packing different solid spheres into containers of the following types: a cuboid, a sphere, a right circular cylinder, an annular cylinder, and a spherical layer. The radii of spheres are assumed to vary. WebThe comparative evaluation of the efficiency of the two cylinder packing algorithms, CPA-MinOSA and CPA-MaxNSA, was based on their execution time to solve the test instances. The results obtained are shown in Fig. 9. As expected, CPA-MinOSA expends considerably more time to reach the final solution than CPA-MaxNSA.
