چکیده
In this note, we point out two major errors in the paper “Minimizing total tardiness on parallel machines with preemptions” by Kravchenko and Werner [2010]. More precisely, they proved that both problems P |pmtn| ∑ Tj and P |rj , pj = p, pmtn| ∑ Tj are NP-Hard. We give a counterexample to their proofs, letting the complexity of these two problems open.

Minimizing total tardiness on parallel machines with preemptions
In this note, we correct a mistake which was made in the paper “Minimizing Total Tardiness on Parallel Machines with Preemptions’ (see Journal of Scheduling, Vol. 15, 2012, 193 200).
متن کاملMinimizing a Separable Convex Function on Parallel Machines with Preemptions
The basic scheduling problem we are dealing with in this paper is the following one. A set of jobs has to be scheduled on a set of parallel uniform machines. Each machine can handle at most one job at a time. All jobs have the same execution requirement. Each machine has a known speed. The processing of any job may be interrupted arbitrarily often and resumed later on any machine. The goal is t...
متن کاملFuzzy Programming for Parallel Machines Scheduling: Minimizing Weighted Tardiness/Earliness and Flow Time through Genetic Algorithm
Appropriate scheduling and sequencing of tasks on machines is one of the basic and significant problems that a shop or a factory manager encounters; this is why in recent decades extensive studies have been done on scheduling issues. One type of scheduling problems is just-in-time (JIT) scheduling and in this area, motivated by JIT manufacturing, this study investigates a mathematical model for...

متن کاملDesign of a Hybrid Genetic Algorithm for Parallel Machines Scheduling to Minimize Job Tardiness and Machine Deteriorating Costs with Deteriorating Jobs in a Batched Delivery System
This paper studies the parallel machine scheduling problem subject to machine and job deterioration in a batched delivery system. By the machine deterioration effect, we mean that each machine deteriorates over time, at a different rate. Moreover, job processing times are increasing functions of their starting times and follow a simple linear deterioration. The objective functions are minimizin...
