Optimize Unrelated Parallel Machines Scheduling Problems With Multiple Limited Additional Resources, Sequence-Dependent Setup Times and Release Date Constraints

open access: yesIEEE Access, 2019
This paper considers the problem of scheduling a set of jobs on unrelated parallel machines subject to several constraints which are non-zero arbitrary release dates, limited additional resources, and non-anticipatory sequence-dependent setup times.

On parallelism in turing machines [PDF]

open access: yes17th Annual Symposium on Foundations of Computer Science (sfcs 1976), 1976
A model of parallel computation based on a generalization of nondeterminism in Turing machines is introduced. Complexity classes //T(n)-TIME, //L(n)-SPACE, //LOGSPACE, //PTIME, etc. are defined for these machines in a way analogous to T(n)-TIME, L(n)-SPACE, LOGSPACE, PTIME, etc. for deterministic machines.

Uniform Parallel-Machine Scheduling for Minimizing Total Resource Consumption With a Bounded Makespan

open access: yesIEEE Access, 2017
This paper examines the uniform parallel-machine scheduling problem in which the objective aims to minimize the total resource consumption (TRC) with a bounded makespan. A matheuristic is proposed to deal with this strongly NP-hard problem.

Abstract And-Parallel Machines.

open access: yesComput. Artif. Intell., 2000
Several abstract models of fine-grained parallelism, suited to symbolic programming languages, are suggested. The first, the  and-parallel Turing machine, can be viewed as a generalization of the deterministic Turing machine in which the infinite tape is replaced by an infinite tree-like tape on which processors work in parallel.

A Combinatorial Approximation Algorithm for the Vector Scheduling with Submodular Penalties on Parallel Machines

open access: yesJournal of Mathematics, 2023
In this paper, we focus on solving the vector scheduling problem with submodular penalties on parallel machines. We are given n jobs and m parallel machines, where each job is associated with a d-dimensional vector.

Resource constraint scheduling on two dedicated machines: Application to avionics

open access: yesEURO Journal on Computational Optimization
In civil aircraft, two partially redundant hydraulic circuits typically power various systems. During assembly, a critical phase involves simultaneously rinsing and purging these hydraulic circuits using loops.
