International Transactions in Operational Research, EarlyView.Abstract We address the scheduling conflicting jobs on parallel identical machines problem with makespan minimization, a classical and computationally challenging variant of parallel machine scheduling. We develop and evaluate three distinct solution methodologies: a novel constraint programming (CP) formulation, and two metaheuristics: a multi ...

A polynomial algorithm for special case of the one-machine scheduling problem with time-lags [PDF]
The standard one-machine scheduling problem consists in scheduling a set of jobs in one machine which can handle only one job at a time, minimizing the maximum lateness.

Optimization of structural assembly scheduling in the aeronautics industry
International Transactions in Operational Research, EarlyView.Abstract In the aeronautical industry, structural assembly refers to the stage in which parts, subassemblies, and main aircraft structures are fitted together, forming aerostructures. Aircraft structural assembly requires many complex activities to be performed over an intricate precedence network and is subject to interactions among the various ...

Deep Cutting Plane Inequalities for Stochastic Non-Preemptive Single Machine Scheduling Problem
American Journal of Operations Research, 2015 We study the classical single machine scheduling problem but with uncertainty. A robust optimization model is presented, and an effective deep cut is derived. Numerical experiments show effectiveness of the derived cut.

A genetic algorithm for scheduling an automated machine cell with tool and pallet–fixture setups
International Transactions in Operational Research, EarlyView.Abstract This paper solves the scheduling problem of identical parallel machines with tooling and pallet–fixture constraints in a high‐mix, low‐volume, high‐complexity manufacturing environment. The machines are connected through an automated material handling device and in‐between buffer places that allow for autonomous production.

Efficient exact formulations for the flexible job shop scheduling with flexible maintenance
International Transactions in Operational Research, EarlyView.Abstract In modern manufacturing systems, integrating preventive maintenance into production scheduling is essential to ensure operational efficiency and equipment reliability. This paper addresses the flexible job shop scheduling problem under machine unavailability constraints caused by non‐fixed maintenance tasks.

Genomic variation drives plant flavor diversification
Journal of Integrative Plant Biology, EarlyView.This review explains how genomic variation shapes plant flavor by altering the biosynthetic and regulatory pathways of key attributes like sweetness, acidity, bitterness, piquancy, astringency, and aroma. It also discusses how multi‐omics, AI‐assisted breeding, and gene editing can translate this knowledge into plants with improved flavor, nutrition ...

An Exact Approach to Early/Tardy Scheduling with Release Dates [PDF]
In this paper we consider the single machine earliness/tardiness scheduling problem with di?erent release dates and no unforced idle time. The problem is decomposed into a weighted earliness subproblem and a weighted tardiness subproblem.

Autoimmunity and Periodontitis
Journal of Periodontal Research, EarlyView.In a microbe‐driven inflammatory environment, peptidyl‐arginine deiminase (PAD) enzymes from neutrophils and Porphyromonas gingivalis citrullinate both microbial and self‐antigens. B cell presentation of citrullinated or self‐mimicking epitopes activates T cells that assist B cells in antibody isotype switching, affinity maturation, epitope spreading ...
