Machine scheduling problemUPMSP? 2023 Elsevier LtdThis paper proposes and evaluates a matheuristic approach for the Unrelated Parallel Machine Scheduling Problem (UPMSP). The UPMSP consists of assigning jobs to
Therefore, the unrelated parallel machines scheduling problem with sequence and machine dependent setup times, machine eligibility restrictions and rework processes to minimize the makespan is strongly NP-hard as well. Due to the complexity of problem, exact algorithms are inefficient for medium and ...

In the first phase, a mathematical model of a single machine scheduling problem, of which the objective is a weighted sum of the three objectives, is constructed. Such a model will be repeatedly solved by the CPLEX in the proposed Multi-Objective Simulated Annealing (MOSA) algorithm. In the ...
Abstract Scheduling has an immense effect on various areas of human lives, be it though its application in manufacturing and production industry, transportation, workforce allocation, or others. The unrelated parallel machines scheduling problem (UPMSP), which is one of the various problem types that...
In this paper we consider unrelated parallel machine scheduling problems that involve the minimization of regular total cost functions. We first present some properties of optimal solutions and then provide a lower bound. These mechanisms are tested on the well-known practical problem of minimizing ...
This paper considers the problem of scheduling jobs on unrelated parallel machines when machine vacations are specified. Two cases are considered, first, when the machine vacations are known apriori, and the second, when these constraints are not known apriori. Algorithms have been developed for ...
Kramer et al. (2021) also propose a B&P algorithm based on set covering (SC) formulation. Since we study unrelated parallel machine scheduling with sequence-dependent setup times, which is different from their research problems, we tailor their B&P algorithm to adapt to the problem at hand. ...

The particularity in the identical parallel machines scheduling case is that the processing time for each job j is the same for all machines. A more general case is the uniform parallel machines scheduling problem. Here, the processing time of a job j depends on the machine i, i∈M to ...
