N2 - We study the problem of non-preemptively scheduling n jobs, each job j with a release time tj, a deadline dj, and a processing time pj, on m parallel identical machines. Cieliebak et al. (2004) considered the two constraints | dj- tj| ≤ λpj and | dj- tj| ≤ pj+ σ and showed the problem to be NP-hard for any λ> 1 and for any σ≥ 2. We complement their results by parameterized complexity studies: we show that, for any λ> 1 , the problem remains weakly NP-hard even for m= 2 and strongly W[1]-hard parameterized by m. We present a pseudo-polynomial-time algorithm for constant m and λ and a fixed-parameter tractability result for the parameter m combined with σ.
