摘要:

We consider the nth power metric facility location problem with linear penalties ((MFLPLP)-F-n) in this work, extending both the nth power metric facility location problem ((MFLP)-F-n) and the metric facility location problem with linear penalties (MFLPLP). We present an LP-rounding based approximation algorithm to the (MFLPLP)-F-n with bi-factor approximation ratio (gamma(f), gamma(c)), where gamma(f) and gamma(c) are the ratios corresponding to facility, and connection and penalty costs respectively. Finally we show that the bi-factor curve is close to the lower bound (gamma(f), 1+(3(n) - 1) e(-gamma f)) when the facility factor gamma(f) > 2 for theM(2)FLPLP.
