An exact approach for the multicommodity network optimization problem with a step cost function
( EDP Sciences , 2019 , Article)We investigate the Multicommodity Network Optimization Problem with a Step Cost Function (MNOP-SCF) where the available facilities to be installed on the edges have discrete step-increasing cost and capacity functions. ... -
Exact solution methods for a generalized assignment problem with location/allocation considerations
( INFORMS Inst.for Operations Res.and the Management Sciences , 2016 , Article)We investigate modeling approaches and exact solution methods for a generalized assignment problem with location/allocation (GAPLA) considerations. In contrast with classical generalized assignment problems, each knapsack ... -
