Scheduling jobs with position-dependent processing times
Bachman and Janiak provided a sketch of the proof that the problem 1|ri,pi(v)1⁄4 ai/v|Cmax is NP-hard in the strong sense. However, they did not show how to avoid using harmonic numbers whose encoding is not pseudo-polynomial, which makes the proof incomplete. In this corrigendum, we provide a new complete proof.

متن کاملScheduling Jobs with Equal Processing Times
Whereas the overwhelming majority of scheduling problems appears to be NP-hard, models with equal processing time jobs form a remarkable case which is still open for most problems but it intuitively looks polynomially solvable. The basic scheduling problem we are dealing with is the following. There are n jobs, each requiring an identical execution time p. There are associated a release time rj...
متن کاملScheduling jobs with position and sum-of-processing-time based processing times
The paper is devoted to some single-machine scheduling problems with variable job processing times. The objectives are to minimize the makespan (i.e., the maximum completion time of all jobs), and to minimize the total completion time. For some special cases, we show that these problems can be solved in polynomial time. For some another special cases of the makespan and the total completion tim...
متن کاملSingle-machine scheduling problems with past-sequence-dependent delivery times and position-dependent processing times
We consider single-machine scheduling problems with past-sequence-dependent (p-s-d) job delivery times. The p-s-d delivery time is needed to remove any waiting time-induced adverse effects on the job’s condition (prior to delivering the job to the customer) and it is therefore proportional to the job’s waiting time. We show that single-machine scheduling problems with p-s-d delivery times and w...
متن کاملScheduling jobs on parallel machines with sequence-dependent setup times
The study considers the scheduling problem of identical parallel machines subject to minimization of the maximumcompletion time and the maximum tardiness expressed in a linear convex objective function. The maximum completiontime or makespan is the date when the last job to be completed leaves the system. The maximum tardiness is indicated bythe job that is completed with the lo...
