Approximation Results for Makespan Minimization with Budgeted Uncertainty

Abstract: We study approximation algorithms for the problem of minimizing the makespan on a set of machines with uncertainty on the processing times of jobs. In the model we consider, which goes back to [3], once the schedule is defined an adversary can pick a scenario where deviation is added to some of the jobs' processing times. Given only the maximal cardinality of these jobs, and the magnitude of potential deviation for each job, the goal is to optimize the worst-case scenario. We consider both the cases of identic… Show more

“…Further, in the current paper it is proved that approximation results of standard bin packing in the form of asymptotic approximation scheme, cannot carry over (unless P = N P) to the robust counterpart with U Γ . While in previous papers [10,9] (with authors in common) we provided approximability results on robust scheduling, no such results have yet been proposed for the bin packing problem, the only previous work focusing on numerical algorithms [25]. The purpose of this paper is to fill these gaps, as we present constant-factor approximation algorithms the bin packing problem, both for U Ω and U Γ .…”

“…Interestingly, these positive results do not extend to most scheduling problems (because they involve nonlinearities) and to the bin packing problem (because it involves a non-constant numbers of robust constraints). While in previous papers [13,12] (with authors in common) we provided approximability results on robust scheduling, no such results have yet been proposed for the bin packing problem, the only previous work focusing on numerical algorithms [27]. The purpose of this paper is to fill these gaps, as we present constant-factor approximation algorithms the bin packing problem, both for U Ω and U Γ .…”

“…Sticking to U Γ , the authors of [5] prove that the robust counterpart of 1|| C j with uncertain processing times is polynomially solvable. They further provide constant factor approximations algorithms for scheduling problems with parallel machines, later improved in [4]. The related bin-packing problem has also been investigated in [3], where the authors provide constant factor approximation algorithms.…”
