An efficient Pareto approach for solving the multi-objective flexible job-shop scheduling problem with regular criteria
(Journal article; Peer reviewed, 2019)In this paper, a general local search approach for the Multi-Objective Flexible Job-shop Scheduling Problem (MOFJSP) is proposed to determine a Pareto front for any combination of regular criteria. The approach is based ... -
Dynamic dispatching and preventive maintenance for parallel machines with dispatching-dependent deterioration
(Journal article; Peer reviewed, 2020)A dynamic decision model that coordinates dispatching and preventive maintenance decisions for failure- prone parallel machines in make-to-order (MTO) production environments is developed in this research. The primary ... -
A lexicographic optimization approach for a bi-objective parallel-machine scheduling problem minimizing total quality loss and total tardiness
(Peer reviewed; Journal article, 2023)In wafer fabrication, production quality is a key performance index and is subject to machine condition deterioration. This paper studies a parallel-machine scheduling problem that can typically be found in the photolithography ... -
Maximizing the service level on the makespan in the stochastic flexible job-shop scheduling problem
(Peer reviewed; Journal article, 2023)This paper considers the flexible job-shop scheduling problem with stochastic processing times. To find a sequence insensitive to shop floor disturbances, the available probabilistic information related to the variability ... -
Minimizing the sum of completion times on a single machine with health index and flexible maintenance operations
(Peer reviewed; Journal article, 2022)This paper is motivated by the development of Industry 4.0 and the need to better integrate production and maintenance decisions. Our problem considers a single machine on which jobs of different families are scheduled to ... -
Optimizing multiple qualifications of products on non-identical parallel machines
(Peer reviewed; Journal article, 2022)In some manufacturing contexts, such as semiconductor manufacturing, machines must be qualified, or eligible, to process a product, and machines cannot be qualified for all products. This paper investigates the problem of ... -
Parallel Machine Scheduling with Time Constraints on Machine Qualifications
(Journal article; Peer reviewed, 2019)This paper studies the scheduling of jobs of different families on parallel machines, where not all machines are qualified (eligible) to process all job families. Originating from semiconductor manufacturing, an important ... -
A queue‐based aggregation approach for performance evaluation of a production system with an AMHS
(Journal article; Peer reviewed, 2020)Production planning optimization remains a major challenge in almost all industries, particularly in high-tech manufacturing. A critical task to support such optimization is performance evaluation, wherein an accurate ...
