Many real-world scheduling problems are solved
to obtain optimal solutions in term of processing time, cost,
and quality as optimization objectives. Currently, energyefficiency
is also taken into consideration in these ...
In this work a genetic algorithm is presented for the unrelated parallel machine scheduling problem in which machine and job sequence dependent setup times are considered. The proposed genetic algorithm includes a fast ...
[EN] The manufacturer industry is characterized by the presence of highly repetitive movements, which is a major risk factor associated with work musculoskeletal disorders (WMSDs). Moreover, this risk factor worsens when ...
[EN] Purpose: This paper reviews current literature and contributes a set of findings that capture the
current state-of-the-art of the topic of lot streaming in a flow-shop.
Design/methodology/approach: A literature ...
This paper deals with a variant of flowshop scheduling, namely, the hybrid or flexible flowshop with sequence dependent setup times. This type of flowshop is frequently used in the batch production industry and helps reduce ...
Lot-streaming flow shops have important applications in different industries including textile, plastic,
chemical, semiconductor and many others. This paper considers an n-job m-machine lot-streaming
flow shop scheduling ...

[EN] This work presented in this paper is based on the simulation of the routing flexibility enabled manufacturing system. In this study four levels of each factor (i.e. routing flexibility, system load conditions, system ...
[EN] The traditional production scheduling problem considers performance
indicators such as processing time, cost and quality as optimization objectives in
manufacturing systems; however, it does not take energy consumption ...

[EN] This paper provides practitioners with new approaches for solving realistic scheduling problems that consider additional resources, which can be implemented on expert and intelligent systems and help decision making ...
[EN] In this paper, we study the unrelated parallel machine scheduling problem with one scarce additional resource to minimise the maximum completion time of the jobs or makespan. Several heuristics are proposed following ...
Task scheduling has a significant impact on the performance of the MapReduce computing
framework. In this paper, a scheduling problem of periodical batch jobs with makespan minimization
is considered. The problem is ...
[EN] Large manufacturing firms operate more than one production center. As a result, in relation to scheduling problems, which factory manufactures which product is an important consideration. In this paper we study an ...

[ES] En este trabajo se pretende resolver el problema de secuenciación de máquinas
paralelas no relacionadas con ajustes entre trabajos y recursos limitados adicionales.
El objetivo del problema es minimizar el tiempo ...
[EN] In this paper we analyze a parallel machine scheduling problem in which the processing of jobs on the machines requires a number of units of a scarce resource. This number depends both on the job and on the machine. ...
