Consider a network facility location problem where congestion arises at facilities, and is represented by delay functions that approximate the queueing process. We strive to minimize the sum of customers' transportation and waiting times, and facilities' xed and variable costs. The problem is solved using a column generation technique within a Branch-and-Bound scheme. Numerical results are repo...

We consider the floating body problem in vertical plane on a large space scale. More precisely, we are interested numerical modeling of freely water such as icebergs or wave energy converters. The fluid-solid interaction is formulated using congested shallow model for fluid and Newton’s second law motion solid. make particular focus transfer between solid since it major interest production.
