Optimal tilt lifting of beams as a min-max problem
This paper considers the problem of finding the optimal pickup points for a beam that is to be tilt lifted by a system of slings attached to a crane. Under the assumptions of a rigid beam and inextensible cables, this task is formulated as a min-max optimization problem. As for its numerical solution, we propose an efficient and robust algorithm involving smoothing and an appropriate discretization of the objective function. A typical numerical example is provided to illustrate the approach.
