the basic type of assembly line balancing (alb) problem is the allocation of work elements to a set of production work stations considering cycle time, precedence constraints, and assembly diagram to achieve predefined performance criteria such as line efficiency and smoothness index. in this paper, a mixed integer programming model for solving multiple product alb problems with processing time...

BACKGROUND The aim of the present study was to assess plantar pressure distribution and musculoskeletal symptoms following the use of customized insoles among female assembly line workers. METHODS The study included 29 female assembly line workers (age, 29.76 ± 5.79 years; weight, 63.79 ± 12.11 kg) with musculoskeletal symptoms who work predominantly while standing. The Nordic Musculoskeletal...

Abstract Currently, the largest percentage of employed workforce in manufacturing industry is involved assembly process, making ergonomics a key factor when dealing with assembly-related problems. During these processes, repetitive tasks and heavy component handling are frequent for workers, who may result overloaded from an energetic point view, thus affecting several aspects not only relating...

We explore judges’ approaches to asylum court appeals based on the issue of conversion from Islam Christianity. Our ethnography in Germany and Austria 2018 2019 provides an insight into how such claims are discussed during appeals. At time, they were increasingly common, especially concerning Iranians Afghans involved ‘free churches’ (e.g. Evangelical, Pentecostal or charismatic). show rumours,...

Workers scheduling in not highly automated production lines is an important task, especially when in a production line the number of operators is less than the number of workstations. Finding an optimal distribution plan can increase the line throughput, managing the workforce and the workload in a better way. This work focuses on the operator-scheduling problem for an electromechanical assembl...

This paper describes a study of using the concept of augmented reality for supporting assembly line workers in carrying out their task optimally. By overlaying virtual information on real world objects – and thereby enhance the human’s perception of reality – augmented reality makes it possible to improve the visual guidance to the workers. In the study, a prototype system is developed based on...

In this paper we consider the programming of job rotation in the Assembly Line Worker Assignment and Balancing Problem. The motivation for this study comes from the designing of assembly lines in sheltered work centers for the disabled, where workers have different task execution times. In this context, the well-known training aspects associated with job rotation are particularly desired. We pr...
